Asclepiades ( Greek : Ἀσκληπιάδης ; c. 129/124 BC – 40 BC ), sometimes called Asclepiades of Bithynia or Asclepiades of Prusa , was a Greek physician born at Prusias-on-Sea in Bithynia in Anatolia and who flourished at Rome , where he practised and taught Greek medicine. He attempted to build a new theory of disease, based on the flow of " atoms " through pores in the body. His treatments sought to restore harmony through the use of diet , exercise, and bathing.

136-532: A constriction of the pores or an obstruction of them by an excess of atoms; Chronic diseases were caused by a relaxation of the pores or a deficiency of atoms. Asclepiades thought that other mild diseases were caused by a disruption in bodily fluids and pneuma . He separated illnesses into three separate categories: status strictus (too tightly held), status laxus (too loosely held), and status mixtus (a little of each). He also believed that there were no critical days of diseases, meaning that illnesses do not end at

204-566: A definite time. Asclepiades' remedies were, therefore, directed to the restoration of harmony. He trusted much to changes in diet, massages, bathing and exercise, although he did employ emetics and bleeding . A part of the great popularity which he enjoyed depended upon his prescribing the liberal use of wine to his patients, and upon his attending to their every need, and indulging their inclinations. He would treat all his patients fairly and did not discriminate based on gender or mental illness. He believed treating his patients kindly and amicably

272-526: A homogeneous natural substance (e.g., flesh, bone, or wood) could be divided and still retain its essential character. Unlike the atomism of Democritus, these Aristotelian "natural minima" were not conceptualized as physically indivisible. Instead, Aristotle's concept was rooted in his hylomorphic worldview, which held that every physical thing is a compound of matter (Greek hyle ) and of an immaterial substantial form (Greek morphe ) that imparts its essential nature and structure. To use an analogy we could pose

340-462: A kind that can be perceived. Epicurus' ideas re-appear in the works of his Roman follower Lucretius ( c.  99 BC – c. 55 BC), who wrote On the Nature of Things . This Classical Latin scientific work in poetic form illustrates several segments of Epicurean theory on how the universe came into its current stage; it shows that the phenomena we perceive are actually composite forms. The atoms and

408-453: A large amount of the element water, and smaller amounts of the other elements. But whatever water or other elements were left, they would no longer have the "nature" of flesh: in hylomorphic terms, they would no longer be matter structured by the form of flesh; instead the remaining water, e.g., would be matter structured by the form of water, not by the form of flesh. Epicurus (341–270 BCE) studied atomism with Nausiphanes who had been

476-467: A modification of the atomic or corpuscular theory, according to which disease results from irregular or inharmonious motion of the corpuscles of the body. His ideas were likely partly derived from the atomic theories of Democritus and Epicurus . All morbid action was reduced to the obstruction of pores and irregular distribution of atoms. Asclepiades arranged diseases into two great classes: Acute and Chronic . Acute diseases were caused essentially by

544-452: A more effective method of treating diseases than had been before known to the world. He decried the efforts of those who sought to investigate the structure of the body, or to watch the phenomena of disease , and he is said to have directed his attacks, particularly, against the writings of Hippocrates . Discarding the humoral doctrine of Hippocrates, Asclepiades attempted to build a new theory of disease, and founded his medical practice on

612-440: A plausible account of changes among the primary substances. Sometime before 330 BC Aristotle asserted that the elements of fire, air, earth, and water were not made of atoms, but were continuous. Aristotle considered the existence of a void, which was required by atomic theories, to violate physical principles. Change took place not by the rearrangement of atoms to make new structures, but by transformation of matter from what it

680-410: A rubber ball: we could imagine the rubber to be the matter that gives the ball the ability to take on another form, and the spherical shape to be the form that gives it its identity of "ball". Using this analogy, though, we should keep in mind that in fact rubber itself would already be considered a composite of form and matter, as it has identity and determinacy to a certain extent, pure or primary matter

748-553: A student of Democritus. Although Epicurus was certain of the existence of atoms and the void, he was less sure we could adequately explain specific natural phenomena such as earthquakes, lightning, comets, or the phases of the Moon. Few of Epicurus' writings survive, and those that do reflect his interest in applying Democritus' theories to assist people in taking responsibility for themselves and for their own happiness—since he held there are no gods around that can help them. (Epicurus regarded

816-493: A void that could divide it. Finally, he stated that the all encompassing Unity is unchanging, for the Unity already encompasses all that is and can be. Democritus rejected Parmenides' belief that change is an illusion. He believed change was real, and if it was not then at least the illusion had to be explained. He thus supported the concept of void, and stated that the universe is made up of many Parmenidean entities that move around in

884-589: Is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms . References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions. Leucippus is the earliest figure whose commitment to atomism is well attested and he is usually credited with inventing atomism. He and other ancient Greek atomists theorized that nature consists of two fundamental principles : atom and void . Clusters of different shapes, arrangements, and positions give rise to

952-473: Is advantageous, excludes them from his life. However, according to science historian Charles Coulston Gillispie: Encased in the Epicurean philosophy, the atomic doctrine could never be welcome to moral authority. ... Epicurean gods neither created the world nor paid it ... attention. "Nature," says Lucretius, "is free and uncontrolled by proud masters and runs the universe by herself without the aid of gods." Only

1020-468: Is assumed that his father was a doctor due to ancient physicians coming from medical families. He received the names Philosophicus due to his knowledge of philosophy and Pharmacion for his knowledge of medicinal herbs. Antiochus of Ascalon said about Asclepiades, "second to none in the art of medicine and acquainted with philosophy too." Asclepiades began by vilifying the principles and practices of his predecessors, and by asserting that he had discovered

1088-453: Is completely unformed, unintelligible and with infinite potential to undergo change. Aristotle's intuition was that there is some smallest size beyond which matter could no longer be structured as flesh, or bone, or wood, or some other such organic substance that for Aristotle (living before the invention of the microscope) could be considered homogeneous. For instance, if flesh were divided beyond its natural minimum, what would be left might be

1156-442: Is composed. In general, however, the belief that a vacuum is impossible was almost universally held until the end of the sixteenth century. ... The time was certainly ripe for the revival of the belief in the possibility of a vacuum, but to the clerics the very name of the vacuum was anathema, being associated with the atomistic theories of Epicurus and Lucretius, which were felt to be heretical. While Aristotelian philosophy eclipsed

Asclepiades

1292-749: The Abhidhammattha-sangaha , a text dated to the 11th or 12th century, postulates the existence of rupa-kalapa , imagined as the smallest units of the physical world, of varying elementary composition. Invisible under normal circumstances, the rupa-kalapa are said to become visible as a result of meditative samadhi . Atomistic philosophies are found very early in Islamic philosophy and were influenced originally by earlier Greek and, to some extent, Indian philosophy. Islamic speculative theology in general approached issues in physics from an atomistic framework. The most successful form of Islamic atomism

1360-861: The Charvaka , and Ajivika schools of atomism originated as early as the 7th century BCE. Bhattacharya posits that Charvaka may have been one of several atheistic, materialist schools that existed in ancient India. Kanada founded the Vaisheshika school of Indian philosophy that also represents the earliest Indian natural philosophy . The Nyaya and Vaisheshika schools developed theories on how kaṇa s combined into more complex objects. Several of these doctrines of atomism are, in some respects, "suggestively similar" to that of Democritus. McEvilley (2002) assumes that such similarities are due to extensive cultural contact and diffusion, probably in both directions. The Nyaya – Vaisesika school developed one of

1428-736: The "distinction which the Eleatic school drew between the Absolute , or the only real existence, and the world of change around us." Democritus believed that atoms are too small for human senses to detect, that they are infinitely many, that they come in infinitely many varieties, and that they have always existed. They float in a vacuum, which Democritus called the "void" , and they vary in form, order, and posture. Some atoms, he maintained, are convex, others concave, some shaped like hooks, and others like eyes . They are constantly moving and colliding into each other. Democritus wrote that atoms and void are

1496-740: The 17th century, a renewed interest arose in Epicurean atomism and corpuscularianism as a hybrid or an alternative to Aristotelian physics . The main figures in the rebirth of atomism were Isaac Beeckman , René Descartes , Pierre Gassendi , and Robert Boyle , as well as other notable figures. One of the first groups of atomists in England was a cadre of amateur scientists known as the Northumberland circle, led by Henry Percy, 9th Earl of Northumberland (1564–1632). Although they published little of account, they helped to disseminate atomistic ideas among

1564-520: The 2nd century AD, credited Asclepiades with being the first individual to perform an elective (non-emergency) tracheotomy . Asclepiades advocated humane treatment of mental disorders and had insane persons freed from confinement and treated them with natural therapy, such as diet and massages. Asclepiades is considered to be a pioneer physician in psychotherapy, physical therapy, and molecular medicine. Notes Atomism Atomism (from Greek ἄτομον , atomon , i.e. "uncuttable, indivisible")

1632-412: The 7th century, was very different from the atomist doctrines taught in early Buddhism. Medieval Buddhist philosophers Dharmakirti and Dignāga considered atoms to be point-sized, durationless, and made of energy. In discussing the two systems, Fyodor Shcherbatskoy (1930) stresses their commonality, the postulate of "absolute qualities" ( guna-dharma ) underlying all empirical phenomena. Still later,

1700-464: The adjacent table. The cube, with its flat base and stability, was assigned to earth; the tetrahedron was assigned to fire because its penetrating points and sharp edges made it mobile. The points and edges of the octahedron and icosahedron were blunter and so these less mobile bodies were assigned to air and water. Since the simple bodies could be decomposed into triangles, and the triangles reassembled into atoms of different elements, Plato's model offered

1768-460: The aggregation and nature of these atoms was predetermined by cosmic forces. The school founder's traditional name Kanada means 'atom eater', and he is known for developing the foundations of an atomistic approach to physics and philosophy in the Sanskrit text Vaiśeṣika Sūtra . His text is also known as Kanada Sutras , or Aphorisms of Kanada. Medieval Buddhist atomism , flourishing around

1836-446: The atomism of Epicurus had fallen out of favor in the centuries of Scholasticism , the minima naturalia of Aristotelianism received extensive consideration. Speculation on minima naturalia provided philosophical background for the mechanistic philosophy of early modern thinkers such as Descartes, and for the alchemical works of Geber and Daniel Sennert , who in turn influenced the corpuscularian alchemist Robert Boyle , one of

1904-685: The atomism of the Asharites and expounded on many Greek texts, especially those of Aristotle. An active school of philosophers in Al-Andalus, including the noted commentator Averroes (1126–1198 CE) explicitly rejected the thought of al-Ghazali and turned to an extensive evaluation of the thought of Aristotle. Averroes commented in detail on most of the works of Aristotle and his commentaries became very influential in Jewish and Christian scholastic thought. According to historian of atomism Joshua Gregory, there

1972-404: The atomists among ... Greek science ... was the one view of nature quite incompatible with theology. Like a pair of eighteenth-century philosophers, Epicurus and Lucretius introduced atomism as a vehicle of enlightenment. They meant to refute the pretensions of religion ... and release men from superstition and the undignified fear of capricious gods. Consequently, a hint of Epicureanism came to seem

2040-824: The burgeoning scientific culture of England, and may have been particularly influential to Francis Bacon , who became an atomist around 1605, though he later rejected some of the claims of atomism. Though they revived the classical form of atomism, this group was among the scientific avant-garde: the Northumberland circle contained nearly half of the confirmed Copernicans prior to 1610 (the year of Galileo's The Starry Messenger ). Other influential atomists of late 16th and early 17th centuries include Giordano Bruno , Thomas Hobbes (who also changed his stance on atomism late in his career), and Thomas Hariot . A number of different atomistic theories were blossoming in France at this time, as well (Clericuzio 2000). Galileo Galilei (1564–1642)

2108-455: The cause of illness. Asclepiades believed that the use of drugs for cleansing was of no use - "all the substances were produced by the drugs themselves", but, rather, "Treatment consists merely of three elements: drink, food and the enema". Asclepiades was heavily influenced by Pythagoreanism and the early work of Democritus on herbal powers and remedies. Pliny the Elder says of him, “Above all, he

2176-659: The curriculum in the universities of Europe was based on such Aristotelianism for most of the Middle Ages. In medieval universities there were, however, expressions of atomism. For example, in the 14th century Nicholas of Autrecourt considered that matter, space, and time were all made up of indivisible atoms, points, and instants and that all generation and corruption took place by the rearrangement of material atoms. The similarities of his ideas with those of al-Ghazali suggest that Nicholas may have been familiar with Ghazali's work, perhaps through Averroes ' refutation of it. In

The work of Democritus survives only in secondhand reports, some of which are unreliable or conflicting. Much of the best evidence of Democritus' theory of atomism is reported by Aristotle (384–322 BCE) in his discussions of Democritus' and Plato 's contrasting views on

2312-555: The direct result of God's constant intervention, without which nothing could happen. Thus nature is completely dependent on God, which meshes with other Asharite Islamic ideas on causation, or the lack thereof (Gardet 2001). Al-Ghazali also used the theory to support his theory of occasionalism . In a sense, the Asharite theory of atomism has far more in common with Indian atomism than it does with Greek atomism. Other traditions in Islam rejected

2380-633: The earliest forms of atomism; scholars date the Nyaya and Vaisesika texts from the 9th to 4th centuries BCE. Vaisesika atomists posited the four elemental atom types, but in Vaisesika physics atoms had 25 different possible qualities, divided between general extensive properties and specific (intensive) properties. The Nyaya–Vaisesika atomists had elaborate theories of how atoms combine. In Vaisesika atomism, atoms first combine into tryaṇuka s (triads) and dvyaṇuka (dyad) before they aggregate into bodies of

2448-488: The early Pythagoreans (before Ecphantus of Syracuse ). Unit-point atomism was invoked in order to make sense of a statement ascribed to Zeno of Elea in Plato's Parmenides : "these writings of mine were meant to protect the arguments of Parmenides against those who make fun of him. . . My answer is addressed to the partisans of the many. . ." The anti-Parmenidean pluralists were supposedly unit-point atomists whose philosophy

2516-412: The founders of modern chemistry. A chief theme in late Roman and Scholastic commentary on this concept was reconciling minima naturalia with the general Aristotelian principle of infinite divisibility . Commentators like John Philoponus and Thomas Aquinas reconciled these aspects of Aristotle's thought by distinguishing between mathematical and "natural" divisibility. With few exceptions, much of

If an illness were to occur, he believed that drugs were not the solution. His prescribed treatment was food and wine (given in appropriate amounts) followed by an enema , which would extract the improper food doing the damage. This procedure would remove

2720-507: The mark of the beast in Christian Europe. No thinker, unless it is Machiavelli, has been more maligned by misrepresentation. The possibility of a vacuum was accepted—or rejected—together with atoms and atomism, for the vacuum was part of that same theory. Democritus and Lucretius denied the impossibility of a vacuum, being of the opinion that there must be a vacuum between the discrete particles (atoms) of which, they thought, all matter

2788-506: The name "atom", long used by the atomist philosophy. Although the connection to historical atomism is at best tenuous, elementary particles have become a modern analogue of philosophical atoms. Philosophical atomism is a reductive argument, proposing not only that everything is composed of atoms and void, but that nothing they compose really exists: the only things that really exist are atoms ricocheting off each other mechanistically in an otherwise empty void . One proponent of this theory

2856-408: The only things that exist and that all other things are merely said to exist by social convention . The objects humans see in everyday life are composed of many atoms united by random collisions and their forms and materials are determined by what kinds of atom make them up. Likewise, human perceptions are caused by atoms as well. Bitterness is caused by small, angular, jagged atoms passing across

However, Epicurus expressed a non-aggressive attitude characterized by his statement: The man who best knows how to meet external threats makes into one family all the creatures he can; and those he can not, he at any rate does not treat as aliens; and where he finds even this impossible, he avoids all dealings, and, so far as

2992-573: The perceiving mind, that is, "secondary" qualities as distinguished from "primary" qualities. Galileo identified some basic problems with Aristotelian physics through his experiments. He utilized a theory of atomism as a partial replacement, but he was never unequivocally committed to it. For example, his experiments with falling bodies and inclined planes led him to the concepts of circular inertial motion and accelerating free-fall. The current Aristotelian theories of impetus and terrestrial motion were inadequate to explain these. While atomism did not explain

3060-420: The present day complete. However, a massive number of fragments and quotations of his writings have survived. These are the main source of information on his teachings about atoms. Democritus's argument for the existence of atoms hinged on the idea that it is impossible to keep dividing matter infinitely - and that matter must therefore be made up of extremely tiny particles. The atomistic theory aimed to remove

3128-624: The role of gods as exemplifying moral ideals.) In ancient Indian philosophy , preliminary instances of atomism are found in the works of Vedic sage Aruni , who lived in the 8th century BCE, especially his proposition that "particles too small to be seen mass together into the substances and objects of experience" known as kaṇa . Although kana refers to "particles" not atoms ( paramanu ). Some scholars such as Hermann Jacobi and Randall Collins have compared Aruni to Thales of Miletus in their scientific methodology, calling them both as "primitive physicists" or "proto-materialist thinkers". Later,

In the 5th century BC, Leucippus and his pupil Democritus proposed that all matter was composed of small indivisible particles which they called "atoms". Nothing whatsoever is known about Leucippus except that he was the teacher of Democritus. Democritus, by contrast, wrote prolifically, producing over eighty known treatises, none of which have survived to

He believed all existence to be a single, all-encompassing and unchanging mass (a concept known as monism ), and that change and motion were mere illusions. He explicitly rejected sensory experience as the path to an understanding of

3400-680: The types of indivisibles composing the natural world. According to some twentieth-century philosophers , unit-point atomism was the philosophy of the Pythagoreans , a conscious repudiation of Parmenides and the Eleatics . It stated that atoms were infinitesimally small ("point") yet possessed corporeality. It was a predecessor of Democritean atomism. Most recent students of presocratic philosophy , such as Kurt von Fritz , Walter Burkert , Gregory Vlastos , Jonathan Barnes , and Daniel W. Graham have rejected that any form of atomism can be applied to

3468-452: The universe and instead used purely abstract reasoning. He believed there is no such thing as void, equating it with non-being. This in turn meant that motion is impossible, because there is no void to move into. Parmenides doesn't mention or explicitly deny the existence of the void, stating instead that what is not does not exist. He also wrote all that is must be an indivisible unity, for if it were manifold, then there would have to be

3536-511: The various macroscopic substances in the world. Indian Buddhists , such as Dharmakirti ( fl. c. 6th or 7th century) and others, developed distinctive theories of atomism, for example, involving momentary (instantaneous) atoms ( kalapa s ) that flash in and out of existence. The particles of chemical matter for which chemists and other natural philosophers of the early 19th century found experimental evidence were thought to be indivisible, and therefore were given by John Dalton

3604-432: The void are eternal and in constant motion. Atomic collisions create objects, which are still composed of the same eternal atoms whose motion for a while is incorporated into the created entity. Lucretius also explains human sensations and meteorological phenomena in terms of atomic motion. In his epic poem On the Nature of Things , Lucretius depicts Epicurus as the hero who crushed the monster Religion through educating

3672-415: The void. The void is infinite and provides the space in which the atoms can pack or scatter differently. The different possible packings and scatterings within the void make up the shifting outlines and bulk of the objects that organisms feel, see, eat, hear, smell, and taste. While organisms may feel hot or cold, hot and cold actually have no real existence. They are simply sensations produced in organisms by

3740-414: Was an advocate of atomism in his 1612 Discourse on Floating Bodies (Redondi 1969). In The Assayer , Galileo offered a more complete physical system based on a corpuscular theory of matter, in which all phenomena—with the exception of sound—are produced by "matter in motion". Atomism was associated by its leading proponents with the idea that some of the apparent properties of objects are artifacts of

This contrasted with the behavior of other physicians who practiced during his lifetime and of whom it was said had a tendency to be uncaring and unsympathetic towards their patients. Digestion was a primary factor in Asclepiades' drug theory. Particles of food were seen as

4080-501: Was essentially a reaction against the Eleatics. This hypothesis, however, to explain Zeno's paradoxes , has been thoroughly discredited. Plato ( c.  427 – c.  347 BCE) argued that atoms just crashing into other atoms could never produce the beauty and form of the world.

Aristotle has often been criticized for rejecting atomism, but in ancient Greece the atomic theories of Democritus remained "pure speculations, incapable of being put to any experimental test". Aristotle theorized minima naturalia as the smallest parts into which

4284-519: Was in the Asharite school of Islamic theology , most notably in the work of the theologian al-Ghazali (1058–1111). In Asharite atomism, atoms are the only perpetual, material things in existence, and all else in the world is "accidental" meaning something that lasts for only an instant. Nothing accidental can be the cause of anything else, except perception, as it exists for a moment. Contingent events are not subject to natural physical causes, but are

4352-470: Was later adapted in the Vaiśeṣika school, which postulated that all objects in the physical universe are reducible to paramāṇu ( atoms ), and one's experiences are derived from the interplay of substance (a function of atoms, their number and their spatial arrangements), quality, activity, commonness, particularity and inherence. Everything was composed of atoms, qualities emerged from aggregates of atoms, but

The square faces of the cube were each made up of four isosceles right-angled triangles and the triangular faces of the tetrahedron, octahedron, and icosahedron were each made up of six right-angled triangles. Plato postulated the geometric structure of the simple bodies of the four elements as summarized in

4488-558: Was no serious work done with atomism from the time of Galen until Isaac Beeckman , Gassendi and Descartes resurrected it in the 17th century; "the gap between these two 'modern naturalists' and the ancient Atomists marked "the exile of the atom" and "it is universally admitted that the Middle Ages had abandoned Atomism, and virtually lost it." Although the ancient atomists' works were unavailable, scholastic thinkers gradually became aware of Aristotle's critiques of atomism as Averroes 's commentaries were translated into Latin .
