115-538: The leader of the attack was the Tyrant Cleisthenes of Sicyon , who used his powerful navy to blockade the city's port before using an allied Amphictionic army to besiege Kirrha. The Athenians also participated with a contingent led by Alcmaeon. On the Thessalian side, the leaders were Eurylochos and Hippias. What transpired after this is a matter of debate: the earliest, and therefore probably most reliable, account

230-542: A deme . The word tyrannos , possibly pre-Greek, Pelasgian or eastern in origin, then carried no ethical censure; it simply referred to anyone, good or bad, who obtained executive power in a polis by unconventional means. Support for the tyrants could come from fellow oligarchs, from the growing middle class or from the peasants who had no land or were in debt to the wealthy landowners. The Greek tyrants stayed in power by using mercenary soldiers from outside of their respective city-state. To mock tyranny, Thales wrote that

345-570: A gymnasium and a colonnade ( peripatos ), from which the school acquired the name Peripatetic . Aristotle conducted courses and research at the school for the next twelve years. He often lectured small groups of distinguished students and, along with some of them, such as Theophrastus , Eudemus , and Aristoxenus , Aristotle built a large library which included manuscripts, maps, and museum objects. While in Athens, his wife Pythias died and Aristotle became involved with Herpyllis of Stagira. They had

460-468: A "prince") with "tyranny", regardless of the legitimacy of that rule, in his Discourses on Livy . He also identifies liberty with republican regimes. Sometimes he calls leaders of republics "princes". He never uses the word in The Prince . He also does not share in the traditional view of tyranny, and in his Discourses he sometimes explicitly acts as an advisor to tyrants. Ancient Greeks , as well as

575-541: A "survival of the fittest" origin of living things and their organs, and ridiculed the idea that accidents could lead to orderly results. To put his views into modern terms, he nowhere says that different species can have a common ancestor , or that one kind can change into another , or that kinds can become extinct . Aristotle did not do experiments in the modern sense. He used the ancient Greek term pepeiramenoi to mean observations, or at most investigative procedures like dissection. In Generation of Animals , he finds

690-491: A bodyguard which he used to seize power. He later appeared with a woman dressed as a goddess to suggest divine sanction of his rule. The third time he used mercenaries to seize and retain power. Lengthy recommendations of methods were made to tyrants by Aristotle (in Politics for example) and Niccolò Machiavelli (in The Prince ). These are, in general, force and fraud. They include hiring bodyguards, stirring up wars to keep

805-519: A complex synthesis of the various philosophies existing prior to him. His teachings and methods of inquiry have had a significant impact across the world, and remain a subject of contemporary philosophical discussion. Aristotle's views profoundly shaped medieval scholarship . The influence of his physical science extended from late antiquity and the Early Middle Ages into the Renaissance , and

920-552: A daughter whom they also named Pythias. In 343/42 BC, Aristotle was invited to Pella by Philip II of Macedon in order to become the tutor to his thirteen-year-old son Alexander ; a choice perhaps influenced by the relationship of Aristotle's family with the Macedonian dynasty. Aristotle taught Alexander at the private school of Mieza , in the gardens of the Nymphs , the royal estate near Pella. Alexander's education probably included

1035-563: A decent resistance, the crafty tyrant submitted to the orders of the senate; and consented to receive the government of the provinces, and the general command of the Roman armies..." Emperors "humbly professed themselves the accountable ministers of the senate, whose supreme decrees they dictated and obeyed." The Roman Empire "may be defined as an absolute monarchy disguised by the forms of a commonwealth." Roman emperors were deified. Gibbons called emperors tyrants and their rule tyranny. His definitions in

1150-515: A democracy, call it anarchy..." The first part of Dante Alighieri 's The Divine Comedy describes tyrants ("who laid hold on blood and plunder") in the seventh level of Hell, where they are submerged in boiling blood. These include Alexander the Great and Attila the Hun , and share the level with highway robbers. Niccolò Machiavelli conflates all rule by a single person (whom he generally refers to as

1265-438: A fertilized hen's egg of a suitable stage and opens it to see the embryo's heart beating inside. Instead, he practiced a different style of science: systematically gathering data, discovering patterns common to whole groups of animals, and inferring possible causal explanations from these. This style is common in modern biology when large amounts of data become available in a new field, such as genomics . It does not result in

1380-497: A fluid such as air. In this system, heavy bodies in steady fall indeed travel faster than light ones (whether friction is ignored, or not ), and they do fall more slowly in a denser medium. Newton's "forced" motion corresponds to Aristotle's "violent" motion with its external agent, but Aristotle's assumption that the agent's effect stops immediately it stops acting (e.g., the ball leaves the thrower's hand) has awkward consequences: he has to suppose that surrounding fluid helps to push

1495-455: A house is the bricks, stones, timbers, etc., or whatever constitutes the potential house, while the form of the substance is the actual house, namely 'covering for bodies and chattels' or any other differentia that let us define something as a house. The formula that gives the components is the account of the matter, and the formula that gives the differentia is the account of the form. Like his teacher Plato, Aristotle's philosophy aims at

1610-462: A large amount of hellebore from Anticyra , where it was abundant. The stories of Frontinus and Polyaenus both have the same result as Thessalos's tale: the defeat of Kirrha. The last major historian to advance a new story of the siege was Pausanias , who was active in the 2nd century. In his version of events, Solon of Athens diverted the course of the River Pleistos to avoid through Kirrha but

1725-597: A linear scale, and noted various exceptions, such as that sharks had a placenta like the tetrapods. To a modern biologist, the explanation, not available to Aristotle, is convergent evolution . Philosophers of science have generally concluded that Aristotle was not interested in taxonomy, but zoologists who studied this question in the early 21st century think otherwise. He believed that purposive final causes guided all natural processes; this teleological view justified his observed data as an expression of formal design. Aristotle's psychology , given in his treatise On

1840-429: A new environment. Conditions were right for Cypselus to overthrow the aristocratic power of the dominant but unpopular clan of Bacchiadae . Clan members were killed, executed, driven out or exiled in 657 BC. Corinth prospered economically under his rule, and Cypselus managed to rule without a bodyguard . When he then bequeathed his position to his son, Periander , the tyranny proved less secure, and Periander required

1955-480: A number of subjects, such as ethics and politics , as well as standard literary texts, like Euripides and Homer . It is likely that during Aristotle's time in the Macedonian court, other prominent nobles, like Ptolemy and Cassander , would have occasionally attended his lectures. Aristotle encouraged Alexander toward eastern conquest, and his own attitude towards Persia was strongly ethnocentric . In one famous example, he counsels Alexander to be "a leader to

2070-435: A part of particular things. For example, it is possible that there is no particular good in existence, but "good" is still a proper universal form. Aristotle disagreed with Plato on this point, arguing that all universals are instantiated at some period of time, and that there are no universals that are unattached to existing things. In addition, Aristotle disagreed with Plato about the location of universals. Where Plato spoke of

2185-498: A priori principles. Aristotle's "natural philosophy" spans a wide range of natural phenomena including those now covered by physics, biology and other natural sciences. In Aristotle's terminology, "natural philosophy" is a branch of philosophy examining the phenomena of the natural world, and includes fields that would be regarded today as physics, biology and other natural sciences. Aristotle's work encompassed virtually all facets of intellectual inquiry. Aristotle makes philosophy in

2300-418: A property or a relation to other things. When one looks at an apple, for example, one sees an apple, and one can also analyse a form of an apple. In this distinction, there is a particular apple and a universal form of an apple. Moreover, one can place an apple next to a book, so that one can speak of both the book and apple as being next to each other. Plato argued that there are some universal forms that are not

2415-550: A retinue of mercenary soldiers personally loyal to him. Nevertheless, under Cypselus and Periander, Corinth extended and tightened her control over her colonial enterprises, and exports of Corinthian pottery flourished. However, tyrants seldom succeeded in establishing an untroubled line of succession. Periander threw his pregnant wife downstairs (killing her), burnt his concubines alive, exiled his son, warred with his father-in-law and attempted to castrate 300 sons of his perceived enemies. He retained his position. Periander's successor

2530-434: A ruler, an illegitimate ruler (a usurper), an absolute ruler (despot), or an oppressive, unjust, or cruel ruler. The term is usually applied to vicious autocrats who rule their subjects by brutal methods. Oppression, injustice, and cruelty do not have standardized measurements or thresholds. Ancient Greek and Sicilian tyrants were influential opportunists that came to power by securing the support of different factions of

2645-602: A set of six books called the Organon around 40 BC by Andronicus of Rhodes or others among his followers. The books are: The order of the books (or the teachings from which they are composed) is not certain, but this list was derived from analysis of Aristotle's writings. It goes from the basics, the analysis of simple terms in the Categories, the analysis of propositions and their elementary relations in On Interpretation , to

2760-549: A son whom Aristotle named after his father, Nicomachus . This period in Athens, between 335 and 323 BC, is when Aristotle is believed to have composed many of his philosophical works. He wrote many dialogues, of which only fragments have survived. Those works that have survived are in treatise form and were not, for the most part, intended for widespread publication; they are generally thought to be lecture aids for his students. His most important treatises include Physics , Metaphysics , Nicomachean Ethics , Politics , On

2875-549: A thrown stone, in the Physics (254b10), and "natural motion", such as of a falling object, in On the Heavens (300a20). In violent motion, as soon as the agent stops causing it, the motion stops also: in other words, the natural state of an object is to be at rest, since Aristotle does not address friction . With this understanding, it can be observed that, as Aristotle stated, heavy objects (on

2990-442: A violent abuse of human beings who are subject to it." While this may represent a consensus position among the classics, it is not unanimous – Thomas Hobbes dissented, claiming no objective distinction, such as being vicious or virtuous, existed among monarchs. "They that are discontented under monarchy, call it tyranny; and they that are displeased with aristocracy, call it oligarchy: so also, they which find themselves grieved under

3105-544: A woman with origins from Chalcis , Euboea . Nicomachus was said to have belonged to the medical guild of Asclepiadae and was likely responsible for Aristotle's early interest in biology and medicine. Ancient tradition held that Aristotle's family descended from the legendary physician Asclepius and his son Machaon . Both of Aristotle's parents died when he was still at a young age and Proxenus of Atarneus became his guardian. Although little information about Aristotle's childhood has survived, he probably spent some time in

3220-425: Is a change where the substrate of the thing that has undergone the change has itself changed. In that particular change he introduces the concept of potentiality ( dynamis ) and actuality ( entelecheia ) in association with the matter and the form. Referring to potentiality, this is what a thing is capable of doing or being acted upon if the conditions are right and it is not prevented by something else. For example,

3335-454: Is a historical accident: his works on botany have been lost, but two books on plants by his pupil Theophrastus have survived. Aristotle reports on the sea-life visible from observation on Lesbos and the catches of fishermen. He describes the catfish , electric ray , and frogfish in detail, as well as cephalopods such as the octopus and paper nautilus . His description of the hectocotyl arm of cephalopods, used in sexual reproduction,

3450-419: Is also a final cause or end. Then Aristotle proceeds and concludes that the actuality is prior to potentiality in formula, in time and in substantiality. With this definition of the particular substance (i.e., matter and form), Aristotle tries to solve the problem of the unity of the beings, for example, "what is it that makes a man one"? Since, according to Plato there are two Ideas: animal and biped, how then

3565-444: Is enslaved, and likewise, the tyrannical state is enslaved, because it too lacks reason and order. The philosophers Plato and Aristotle defined a tyrant as a person who rules without law, using extreme and cruel methods against both his own people and others. The Encyclopédie defined the term as a usurper of sovereign power who makes "his subjects the victims of his passions and unjust desires, which he substitutes for laws". In

3680-468: Is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period . His father, Nicomachus , died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato 's Academy in Athens and remained there until the age of thirty seven ( c.  347 BC ). Shortly after Plato died, Aristotle left Athens and, at

3795-541: Is man a unity? However, according to Aristotle, the potential being (matter) and the actual one (form) are one and the same. Aristotle's immanent realism means his epistemology is based on the study of things that exist or happen in the world, and rises to knowledge of the universal, whereas for Plato epistemology begins with knowledge of universal Forms (or ideas) and descends to knowledge of particular imitations of these. Aristotle uses induction from examples alongside deduction , whereas Plato relies on deduction from

3910-404: Is that of the medical writer Thessalos . He wrote, in the 5th century BC, that the attackers discovered a secret water-pipe leading into the city after it was broken by a horse's hoof. An asclepiad named Nebros advised the allies to poison the water with hellebore which soon rendered the defenders so weak with diarrhea that they were unable to resist the assault. Kirrha was captured and

4025-446: Is the exercise of power beyond right, which nobody can have a right to; and this is making use of the power any one has in his hands, not for the good of those who are under it, but for his own private, separate advantage." Locke's concept of tyranny influenced the writers of subsequent generations who developed the concept of tyranny as counterpoint to ideas of human rights and democracy . American statesman Thomas Jefferson described

4140-413: Is the fulfilment of the end of the potentiality. Because the end ( telos ) is the principle of every change, and potentiality exists for the sake of the end, actuality, accordingly, is the end. Referring then to the previous example, it can be said that an actuality is when a plant does one of the activities that plants do. For that for the sake of which ( to hou heneka ) a thing is, is its principle, and

4255-531: Is the root from which a tyrant springs; when he first appears he is a protector". Tyrants either inherit the position from a previous ruler, rise up the ranks in the military/party or seize power as new men. Early texts called only the usurpers tyrants, distinguishing them from "bad kings". Such tyrants may act as renters, rather than owners, of the state. The political methods of obtaining power were occasionally supplemented by theater or force. Peisistratus of Athens blamed self-inflicted wounds on enemies to justify

4370-452: The Archaic and early Classical periods. However, Greek philosopher Plato saw tyrannos as a negative form of government, and on account of the decisive influence of philosophy on politics, deemed tyranny the "fourth and worst disorder of a state." Tyrants lack "the very faculty that is the instrument of judgment"—reason. The tyrannical man is enslaved because the best part of him (reason)

4485-464: The Dionysia (ultimately leading to the development of Athenian drama), Peisistratus managed to maintain his personal popularity. He was followed by his sons, and with the subsequent growth of Athenian democracy , the title "tyrant" took on its familiar negative connotations. The murder of Peisistratus' son, the tyrant Hipparchus by Aristogeiton and Harmodios in Athens in 514 BC marked the beginning of

4600-634: The Early Modern period. John Philoponus (in Late antiquity ) and Galileo (in Early modern period ) are said to have shown by experiment that Aristotle's claim that a heavier object falls faster than a lighter object is incorrect. A contrary opinion is given by Carlo Rovelli , who argues that Aristotle's physics of motion is correct within its domain of validity, that of objects in the Earth 's gravitational field immersed in

4715-515: The Great Comet of 371 BC . Aristotle was one of the first people to record any geological observations. He stated that geological change was too slow to be observed in one person's lifetime. The geologist Charles Lyell noted that Aristotle described such change, including "lakes that had dried up" and "deserts that had become watered by rivers", giving as examples the growth of the Nile delta since

4830-570: The Greek τύραννος tyrannos "monarch, ruler of a polis "; tyrannos in its turn has a Pre-Greek origin, perhaps from Lydian . The final -t arises in Old French by association with the present participles in -ant . "The word 'tyranny' is used with many meanings, not only by the Greeks but throughout the tradition of the great books." The Oxford English Dictionary offers alternative definitions:

His system had eleven grades of animal, from highest potential to lowest, expressed in their form at birth: the highest gave live birth to hot and wet creatures, the lowest laid cold, dry mineral-like eggs. Animals came above plants , and these in turn were above minerals. He grouped what

5060-496: The Maccabees and Herod the Great . He also identified some later tyrants. The Greeks defined both usurpers and those inheriting rule from usurpers as tyrants. Polybius (c. 150 BC) indicated that eventually, any one-man rule (monarchy/executive) governing form would become corrupted into a tyranny. The Greek philosophers stressed the quality of rule rather than legitimacy or absolutism. "Both Plato and Aristotle speak of

5175-538: The Macedonian capital, making his first connections with the Macedonian monarchy . At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Plato's Academy . He became distinguished as a researcher and lecturer, earning for himself the nickname "mind of the school" by his tutor Plato . In Athens, he probably experienced the Eleusinian Mysteries as he wrote when describing

5290-451: The Milky Way was made up of "those stars which are shaded by the earth from the sun's rays," pointing out partly correctly that if "the size of the sun is greater than that of the earth and the distance of the stars from the earth many times greater than that of the sun, then... the sun shines on all the stars and the earth screens none of them." He also wrote descriptions of comets, including

5405-545: The Peloponnesus and Polycrates ruled Samos . During this time, revolts overthrew many governments in the Aegean world. Chilon , the ambitious and capable ephor of Sparta , built a strong alliance amongst neighboring states by making common cause with these groups seeking to oppose unpopular tyrannical rule. By intervening against the tyrants of Sicyon, Corinth and Athens, Sparta thus came to assume Hellenic leadership prior to

5520-508: The Physics (215a25), Aristotle effectively states a quantitative law, that the speed, v, of a falling body is proportional (say, with constant c) to its weight, W, and inversely proportional to the density, ρ, of the fluid in which it is falling:; Aristotle implies that in a vacuum the speed of fall would become infinite, and concludes from this apparent absurdity that a vacuum is not possible. Opinions have varied on whether Aristotle intended to state quantitative laws. Henri Carteron held

5635-523: The Roman Republicans , became generally quite wary of many people seeking to implement a popular coup. Shakespeare portrays the struggle of one such anti-tyrannical Roman, Marcus Junius Brutus , in his play Julius Caesar . In Gibbon's Decline and Fall of the Roman Empire, Volume I, Chapter III, Augustus was shown to assume the power of a tyrant while sharing power with the reformed senate. "After

5750-551: The Roman Senate . Those who were advocates of "liberty" tended to be pro-Republic and pro-Senate. For instance, regarding Julius Caesar and his assassins, Suetonius wrote: Therefore the plots which had previously been formed separately, often by groups of two or three, were united in a general conspiracy, since even the populace no longer were pleased with present conditions, but both secretly and openly rebelled at his tyranny and cried out for defenders of their liberty. Citizens of

5865-653: The Sword of Damocles . Under the Macedonian hegemony in the 4th and 3rd century BC a new generation of tyrants rose in Greece, especially under the rule of king Antigonus II Gonatas , who installed his puppets in many cities of the Peloponnese. Examples were Cleon of Sicyon , Aristodemus of Megalopolis , Aristomachus I of Argos , Abantidas of Sicyon , Aristippus of Argos , Lydiadas of Megalopolis , Aristomachus II of Argos , and Xenon of Hermione . Against these rulers, in 280 BC

5980-412: The universal . Aristotle's ontology places the universal ( katholou ) in particulars ( kath' hekaston ), things in the world, whereas for Plato the universal is a separately existing form which actual things imitate. For Aristotle, "form" is still what phenomena are based on, but is "instantiated" in a particular substance. Plato argued that all things have a universal form , which could be either

6095-399: The "Great Ideas" of Western thought. The classics contain many references to tyranny and its causes, effects, methods, practitioners, alternatives. They consider tyranny from historical, religious, ethical, political and fictional perspectives. "If any point in political theory is indisputable, it would seem to be that tyranny is the worst corruption of government – a vicious misuse of power and

6210-513: The "extreme view" that Aristotle's concept of force was basically qualitative, but other authors reject this. Archimedes corrected Aristotle's theory that bodies move towards their natural resting places; metal boats can float if they displace enough water ; floating depends in Archimedes' scheme on the mass and volume of the object, not, as Aristotle thought, its elementary composition. Aristotle's writings on motion remained influential until

6325-518: The Colonies , were composed by the philosopher for the young prince. After Philip II's assassination in 336 BC, Aristotle returned to Athens for the second and final time a year later. As a metic , Aristotle could not own property in Athens and thus rented a building known as the Lyceum (named after the sacred grove of Apollo Lykeios ), in which he established his own school. The building included

6440-505: The Greek mainland, Nabis of Sparta , was assassinated in 192 BC and after his death the Peloponnese was united as a confederation of stable democracies in the Achaean League. Roman historians like Suetonius , Tacitus , Plutarch , and Josephus often spoke of "tyranny" in opposition to "liberty". Tyranny was associated with imperial rule and those rulers who usurped too much authority from

6555-553: The Greeks and a despot to the barbarians". Alexander's education under the guardianship of Aristotle likely lasted for only a few years, as at around the age of sixteen he returned to Pella and was appointed regent of Macedon by his father Philip. During this time, Aristotle is said to have gifted Alexander an annotated copy of the Iliad , which reportedly became one of Alexander's most prized possessions. Scholars speculate that two of Aristotle's now lost works, On kingship and On behalf of

6670-565: The Greeks on behalf of the Persians and provided military advice to the Persians against the Greeks. The Thirty Tyrants whom the Spartans imposed on a defeated Attica in 404 BC would not be classified as tyrants in the usual sense and were in effect an oligarchy . The best known Sicilian tyrants appeared long after the Archaic period. The tyrannies of Sicily came about due to similar causes, but here

6785-481: The Magna Carta), Henry VIII of England and Oliver Cromwell . The path of a tyrant can appear easy and pleasant (for all but the aristocracy). In 1939, Will Durant wrote: Hence the road to power in Greece commercial cities was simple: to attack the aristocracy, defend the poor, and come to an understanding with the middle classes. Arrived at power, the dictator abolished debts, or confiscated large estates, taxed

6900-604: The Persian invasions. Simultaneously Persia first started making inroads into Greece, and many tyrants sought Persian help against popular forces seeking to remove them. Corinth hosted one of the earliest of Greek tyrants. In Corinth , growing wealth from colonial enterprises, and the wider horizons brought about by the export of wine and oil, together with the new experiences of the Eastern Mediterranean brought back by returning mercenary hoplites employed overseas created

7015-699: The Persians, and philosophical questions, like the definition of braveness. A widespread speculation in antiquity suggested that Aristotle played a role in Alexander's death, but the only evidence of this is an unlikely claim made some six years after the death. Following Alexander's death, anti-Macedonian sentiment in Athens was rekindled. In 322 BC, Demophilus and Eurymedon the Hierophant reportedly denounced Aristotle for impiety, prompting him to flee to his mother's family estate in Chalcis, Euboea , at which occasion he

7130-487: The Soul and Poetics . Aristotle studied and made significant contributions to "logic, metaphysics, mathematics, physics, biology, botany, ethics, politics, agriculture, medicine, dance, and theatre." While Alexander deeply admired Aristotle, near the end of his life, the two men became estranged having diverging opinions over issues, like the optimal administration of city-states, the treatment of conquered populations, such as

7245-576: The actions of King George III as "tyrannical" in the United States Declaration of Independence . Enlightenment philosophers seemed to define tyranny by its associated characteristics. Edward Sexby's 1657 pamphlet, "Killing, No Murder" ( PDF file ) outlined 14 key traits of a tyrant, as the pamphlet was written to inspire the assassination of Oliver Cromwell, and show in what circumstances an assassination might be considered honorable. The full document mulls over and references points on

7360-579: The aristocracy the people destroyed the dictatorship; and only a few changes were needed to make democracy of freemen a reality as well as a form. Ancient Greek philosophers (who were aristocrats) were far more critical in reporting the methods of tyrants. The justification for ousting a tyrant was absent from the historian's description but was central to the philosophers. In the Republic , Plato stated: "The people have always some champion whom they set over them and nurse into greatness. [...] This and no other

7475-489: The ball along to make it continue to rise even though the hand is no longer acting on it, resulting in the Medieval theory of impetus . Aristotle suggested that the reason for anything coming about can be attributed to four different types of simultaneously active factors. His term aitia is traditionally translated as "cause", but it does not always refer to temporal sequence; it might be better translated as "explanation", but

7590-399: The becoming is for the sake of the end; and the actuality is the end, and it is for the sake of this that the potentiality is acquired. For animals do not see in order that they may have sight, but they have sight that they may see. In summary, the matter used to make a house has potentiality to be a house and both the activity of building and the form of the final house are actualities, which

7705-574: The broad sense coextensive with reasoning, which he also would describe as "science". However, his use of the term science carries a different meaning than that covered by the term "scientific method". For Aristotle, "all science ( dianoia ) is either practical, poetical or theoretical" ( Metaphysics 1025b25). His practical science includes ethics and politics; his poetical science means the study of fine arts including poetry; his theoretical science covers physics, mathematics and metaphysics. In his On Generation and Corruption , Aristotle related each of

7820-433: The cause of earthquakes was a gas or vapor ( anathymiaseis ) that was trapped inside the earth and trying to escape, following other Greek authors Anaxagoras , Empedocles and Democritus . Aristotle also made many observations about the hydrologic cycle. For example, he made some of the earliest observations about desalination: he observed early – and correctly – that when seawater is heated, freshwater evaporates and that

7935-537: The chapter were related to the absolutism of power alone – not oppression, injustice or cruelty. He ignored the appearance of shared rule. During the Age of Enlightenment , Western thinkers applied the word tyranny to the system of governance that had developed around aristocracy and monarchy . Specifically, English philosopher John Locke , as part of his argument against the " Divine Right of Kings " in his 1689 book Two Treatises of Government , defined it as such: "Tyranny

And it belongs to this sort of philosophy to study being as being, both what it is and what belongs to it just by virtue of being. Aristotle examines

In Book VIII, he distinguishes the matter of the substance as the substratum , or the stuff of which it is composed. For example, the matter of

8395-399: The data to come to the theory of evolution . Aristotle's writings can seem to modern readers close to implying evolution, but while Aristotle was aware that new mutations or hybridizations could occur, he saw these as rare accidents. For Aristotle, accidents, like heat waves in winter, must be considered distinct from natural causes. He was thus critical of Empedocles's materialist theory of

8510-529: The democratic cities started to join forces in the Achaean League which was able to expand its influence even into Corinthia , Megaris , Argolis and Arcadia . From 251 BC under the leadership of Aratus of Sicyon , the Achaeans liberated many cities, in several cases by convincing the tyrants to step down, and when Aratus died in 213 BC, Hellas had been free of tyrants for more than 15 years. The last tyrant on

8625-450: The details of Aristotle's life are not well-established. The biographies written in ancient times are often speculative and historians only agree on a few salient points. Aristotle was born in 384 BC in Stagira , Chalcidice , about 55 km (34 miles) east of modern-day Thessaloniki . He was the son of Nicomachus , the personal physician of King Amyntas of Macedon , and Phaestis,

8740-486: The earliest study of formal logic, and his conception of it was the dominant form of Western logic until 19th-century advances in mathematical logic . Kant stated in the Critique of Pure Reason that with Aristotle, logic reached its completion. Most of Aristotle's work is probably not in its original form, because it was most likely edited by students and later lecturers. The logical works of Aristotle were compiled into

8855-637: The empire were circumspect in identifying tyrants. " Cicero 's head and hands [were] cut off and nailed to the rostrum of the Senate to remind everyone of the perils of speaking out against tyranny." There has since been a tendency to discuss tyranny in the abstract while limiting examples of tyrants to ancient Greek rulers. Josephus identified tyrants in Biblical history (in Antiquities of the Jews) including Nimrod , Moses ,

8970-621: The enemy was able to get enough water from their wells and rainwater collection. Solon then added a great quantity of hellebore to the water of the Pleistos and let it flow into Kirrha. The First Sacred War ended with the victory of the allies of the Amphictyony. Kirrha was destroyed and its lands were dedicated to Apollo, Leto and Artemis and it was forbidden to cultivate them or let animals graze on them. Its inhabitants fled to mountain Kirphe. Cleisthenes

9085-576: The entire population was slaughtered. Nebros was considered an ancestor of Hippocrates , so this story has caused many to wonder whether it might not have been guilt over his ancestor's use of poison that drove Hippocrates to establish the Hippocratic Oath . Later historians told different stories. According to Frontinus , who wrote in the 1st century AD, after discovering the pipe, the Amphictionic League cut it, leading to great thirst within

9200-442: The first century AD editor who assembled various small selections of Aristotle's works to create the treatise we know by the name Metaphysics . Aristotle called it "first philosophy", and distinguished it from mathematics and natural science (physics) as the contemplative ( theoretikē ) philosophy which is "theological" and studies the divine. He wrote in his Metaphysics (1026a16): If there were no other independent things besides

9315-533: The following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period , and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice. Aristotle distinguished about 500 species of animals , arranging these in

9430-531: The forms as existing separately from the things that participate in them, Aristotle maintained that universals exist within each thing on which each universal is predicated. So, according to Aristotle, the form of apple exists within each apple, rather than in the world of the forms. Concerning the nature of change ( kinesis ) and its causes, as he outlines in his Physics and On Generation and Corruption ( 319b–320a), he distinguishes coming-to-be ( genesis , also translated as 'generation') from: Coming-to-be

9545-509: The four elements proposed earlier by Empedocles , earth , water , air , and fire , to two of the four sensible qualities, hot, cold, wet, and dry. In the Empedoclean scheme, all matter was made of the four elements, in differing proportions. Aristotle's scheme added the heavenly aether , the divine substance of the heavenly spheres , stars and planets. Aristotle describes two kinds of motion: "violent" or "unnatural motion", such as that of

9660-428: The ground, say) require more force to make them move; and objects pushed with greater force move faster. This would imply the equation incorrect in modern physics. Natural motion depends on the element concerned: the aether naturally moves in a circle around the heavens, while the 4 Empedoclean elements move vertically up (like fire, as is observed) or down (like earth) towards their natural resting places. In

9775-618: The head of the Lyceum, who in turn passed them down to Neleus of Scepsis in Asia Minor. There, the papers remained hidden for protection until they were purchased by the collector Apellicon . In the meantime, many copies of Aristotle's major works had already begun to circulate and be used in the Lyceum of Athens, Alexandria , and later in Rome . With the Prior Analytics , Aristotle is credited with

9890-440: The image. According to Aristotle, spontaneity and chance are causes of some things, distinguishable from other types of cause such as simple necessity. Chance as an incidental cause lies in the realm of accidental things , "from what is spontaneous". There is also more a specific kind of chance, which Aristotle names "luck", that only applies to people's moral choices. In astronomy , Aristotle refuted Democritus 's claim that

10005-403: The king as a good monarch and the tyrant as a bad one. Both say that monarchy, or rule by a single man, is royal when it is for the welfare of the ruled and tyrannical when it serves only the interest of the ruler. Both make lawlessness – either a violation of existing laws or government by personal fiat without settled laws – a mark of tyranny." Tyranny is considered an important subject, one of

10120-509: The late fifth and fourth centuries BC, a new kind of tyrant, one who had the support of the military , arose – specifically in Sicily . One can apply accusations of tyranny to a variety of types of government: The English noun tyrant appears in Middle English use, via Old French , from the 1290s. The word derives from Latin tyrannus , meaning "illegitimate ruler", and this in turn from

10235-806: The matter from early pre-Christian history, up into the 17th century when the pamphlet was writ. Of the most prevailing traits of tyranny outlined, " Killing, No Murder " emphasizes: [Original 1657 text: https://archive.org/details/killingnomurderb00sexbuoft/page/n3/mode/2up ] In Scotland, Samuel Rutherford's Lex Rex and Alexander Shields' A Hind Let Loose were influential works of theology written in opposition to tyranny. A modern tyrant might be defined by proven violation of international criminal law such as crimes against humanity . Various lists of tyrants include: There are also numerous book titles which identify tyrants by name or circumstances. Among English rulers, several have been identified as tyrants by book title: John, King of England (who signed

10350-399: The modern English usage of the word, is an absolute ruler who is unrestrained by law , or one who has usurped a legitimate ruler's sovereignty. Often portrayed as cruel, tyrants may defend their positions by resorting to repressive means. The original Greek term meant an absolute sovereign who came to power without constitutional right , yet the word had a neutral connotation during

10465-468: The modern zoologist would call vertebrates as the hotter "animals with blood", and below them the colder invertebrates as "animals without blood". Those with blood were divided into the live-bearing ( mammals ), and the egg-laying ( birds , reptiles , fish ). Those without blood were insects, crustacea (non-shelled – cephalopods, and shelled ) and the hard-shelled molluscs ( bivalves and gastropods ). He recognised that animals did not exactly fit into

10580-432: The most part kept out of war, supported religion, maintained order, promoted morality, favored the higher status of women, encouraged the arts, and lavished revenues upon the beautification of their cities. And they did all these things, in many cases, while preserving the forms of popular government, so that even under despotism the people learned the ways of liberty. When the dictatorship [of the tyrant] had served to destroy

10695-404: The oceans are then replenished by the cycle of rainfall and river runoff ("I have proved by experiment that salt water evaporated forms fresh and the vapor does not when it condenses condense into sea water again.") Aristotle was the first person to study biology systematically, and biology forms a large part of his writings. He spent two years observing and describing the zoology of Lesbos and

10810-541: The people busy and dependent, purges , assassinations , and unwarranted searches and seizures. Aristotle suggested an alternative means of retaining power – ruling justly. The methods of tyrants to retain power include placating world opinion by staging rigged elections , using or threatening to use violence, seeking popular support by appeals to patriotism , and claiming that conditions have improved. Aristotle Aristotle ( Attic Greek : Ἀριστοτέλης , romanized:  Aristotélēs ; 384–322 BC)

10925-407: The poet Dante called him "the master of those who know". His works contain the earliest known formal study of logic, and were studied by medieval scholars such as Peter Abelard and Jean Buridan . Aristotle's influence on logic continued well into the 19th century. In addition, his ethics , although always influential, gained renewed interest with the modern advent of virtue ethics . In general,

11040-497: The prosperity of the peasantry and landowning interests of the plain, which was prospering from the rise of olive oil exports, as well as his clients from Marathon , he managed to achieve authoritarian power. Through an ambitious program of public works, which included fostering the state cult of Athena ; encouraging the creation of festivals; supporting the Panathenaic Games in which prizes were jars of olive oil; and supporting

11155-405: The request of Philip II of Macedon , tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls . Though Aristotle wrote many treatises and dialogues for publication, only around a third of his original output has survived , none of it intended for publication. Aristotle provided

11270-406: The rich to finance public works, or otherwise redistributed the over-concentrated wealth; and while attaching the masses to himself through such measures, he secured the support of the business community by promoting trade with state coinage and commercial treaties, and by raising the social prestige of the bourgeoisie. Forced to depend upon popularity instead of hereditary power, the dictatorships for

11385-433: The same certainty as experimental science, but it sets out testable hypotheses and constructs a narrative explanation of what is observed. In this sense, Aristotle's biology is scientific. From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are

11500-439: The seed of a plant in the soil is potentially ( dynamei ) a plant, and if it is not prevented by something, it will become a plant. Potentially, beings can either 'act' ( poiein ) or 'be acted upon' ( paschein ), which can be either innate or learned. For example, the eyes possess the potentiality of sight (innate – being acted upon), while the capability of playing the flute can be possessed by learning (exercise – acting). Actuality

11615-690: The sights one viewed at the Mysteries, "to experience is to learn" ( παθεĩν μαθεĩν ). Aristotle remained in Athens for nearly twenty years before leaving in 348/47 BC after Plato's death. The traditional story about his departure records that he was disappointed with the Academy's direction after control passed to Plato's nephew Speusippus , although it is possible that the anti-Macedonian sentiments in Athens could have also influenced his decision. Aristotle left with Xenocrates to Assos in Asia Minor , where he

11730-535: The so-called "cult of the tyrannicides " (i.e., of killers of tyrants). Contempt for tyranny characterised this cult movement . Despite financial help from Persia, in 510 the Peisistratids were expelled by a combination of intrigue, exile and Spartan arms. The anti-tyrannical attitude became especially prevalent in Athens after 508 BC, when Cleisthenes reformed the political system so that it resembled demokratia . Hippias (Peisistratus' other son) offered to rule

11845-470: The strangest thing to see is "an aged tyrant", meaning that tyrants do not have the public support to survive for long. One of the earliest known uses of the word 'tyrant' (in Greek) was by the poet Archilochus in reference to king Gyges of Lydia . The king's assumption of power was unconventional. The heyday of the Archaic period tyrants came in the early 6th century BC, when Cleisthenes ruled Sicyon in

11960-747: The study of more complex forms, namely, syllogisms (in the Analytics ) and dialectics (in the Topics and Sophistical Refutations ). The first three treatises form the core of the logical theory stricto sensu : the grammar of the language of logic and the correct rules of reasoning. The Rhetoric is not conventionally included, but it states that it relies on the Topics . What is today called Aristotelian logic with its types of syllogism (methods of logical argument), Aristotle himself would have labelled "analytics". The term "logic" he reserved to mean dialectics . The word "metaphysics" appears to have been coined by

12075-549: The surrounding seas, including in particular the Pyrrha lagoon in the centre of Lesbos. His data in History of Animals , Generation of Animals , Movement of Animals , and Parts of Animals are assembled from his own observations, statements given by people with specialized knowledge, such as beekeepers and fishermen, and less accurate accounts provided by travellers from overseas. His apparent emphasis on animals rather than plants

12190-553: The threat of Carthaginian attack prolonged tyranny, facilitating the rise of military leaders with the people united behind them. Such Sicilian tyrants as Gelo , Hiero I , Dionysius the Elder , Dionysius the Younger , and Agathocles of Syracuse maintained lavish courts and became patrons of culture. The dangers threatening the lives of the Sicilian tyrants are highlighted in the moral tale of

12305-470: The time of Homer , and "the upheaving of one of the Aeolian islands , previous to a volcanic eruption ."' Meteorologica lends its name to the modern study of meteorology, but its modern usage diverges from the content of Aristotle's ancient treatise on meteors . The ancient Greeks did use the term for a range of atmospheric phenomena, but also for earthquakes and volcanic eruptions. Aristotle proposed that

12420-473: The traditional rendering will be employed here. Aristotle describes experiments in optics using a camera obscura in Problems , book 15. The apparatus consisted of a dark chamber with a small aperture that let light in. With it, he saw that whatever shape he made the hole, the sun's image always remained circular. He also noted that increasing the distance between the aperture and the image surface magnified

12535-533: Was an Ancient Greek philosopher and polymath . His writings cover a broad range of subjects spanning the natural sciences , philosophy , linguistics , economics , politics , psychology , and the arts . As the founder of the Peripatetic school of philosophy in the Lyceum in Athens , he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science . Little

12650-441: Was generously rewarded with one third of the booty. In order to celebrate the end of the fighting the first Pythian Games were organized with Cleisthenes playing a major part in them. However, modern scholarship is very skeptical on the exact events and on the long duration of the war. Tyrant List of forms of government A tyrant (from Ancient Greek τύραννος ( túrannos )  'absolute ruler'), in

12765-413: Was invited by his former fellow student Hermias of Atarneus ; he stayed there for a few years and left around the time of Hermias' death. While at Assos, Aristotle and his colleague Theophrastus did extensive research in botany and marine biology , which they later continued at the near-by island of Lesbos . During this time, Aristotle married Pythias , Hermias's adoptive daughter and niece, and had

12880-493: Was less fortunate and was expelled. Afterward, Corinth was ruled by a lackluster oligarchy, and was eventually eclipsed by the rising fortunes of Athens and Sparta. Athens hosted its tyrants late in the Archaic period. In Athens , the inhabitants first gave the title of tyrant to Peisistratos (a relative of Solon , the Athenian lawgiver) who succeeded in 546 BC, after two failed attempts, to install himself as tyrant. Supported by

12995-766: Was not replaced systematically until the Enlightenment and theories such as classical mechanics were developed. He influenced Judeo-Islamic philosophies during the Middle Ages, as well as Christian theology , especially the Neoplatonism of the Early Church and the scholastic tradition of the Catholic Church . Aristotle was revered among medieval Muslim scholars as "The First Teacher", and among medieval Christians like Thomas Aquinas as simply "The Philosopher", while

13110-513: Was said to have stated "I will not allow the Athenians to sin twice against philosophy" – a reference to Athens's trial and execution of Socrates . He died in Chalcis, Euboea of natural causes later that same year, having named his student Antipater as his chief executor and leaving a will in which he asked to be buried next to his wife. Aristotle left his works to Theophrastus, his successor as

13225-588: Was widely disbelieved until the 19th century. He gives accurate descriptions of the four-chambered fore-stomachs of ruminants , and of the ovoviviparous embryological development of the hound shark . He notes that an animal's structure is well matched to function so birds like the heron (which live in marshes with soft mud and live by catching fish) have a long neck, long legs, and a sharp spear-like beak, whereas ducks that swim have short legs and webbed feet. Darwin , too, noted these sorts of differences between similar kinds of animal, but unlike Aristotle used
