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.

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

However, according to science historian Charles Coulston Gillispie: Encased in the Epicurean philosophy, the atomic doctrine could never be welcome to moral authority. ...

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

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

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

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

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,

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

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)

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

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

A chief theme in late Roman and Scholastic commentary on this concept was reconciling minima naturalia with the general Aristotelian principle of infinite divisibility .

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

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,

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

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
