Ionian School

The Ionian School, a type of Greek philosophy centred in Miletus, Ionia in the 6th and 5th centuries BC, is something of a misnomer. Although Ionia was a centre of Western philosophy, the scholars it produced, including Anaximander, Anaximenes, Heraclitus, Anaxagoras, Diogenes Apolloniates, Archelaus, Hippo, and Thales, [American International Encyclopedia, J.J. Little Co., New York 1954, Vol VIII] had such diverse viewpoints that it cannot be said to be a specific school of philosophy. Aristotle called them "physiologoi" meaning 'those who discoursed on nature', but he did not group them together as an "Ionian school". The classification can be traced to the second century historian of philosophy Sotion. They are sometimes referred to as cosmologists, since they were largely physicalists who tried to explain the nature of matter.

While some of these scholars are included in the Milesian school of philosophy, others are more difficult to categorize.

Most cosmologists thought that although matter can change from one form to another, all matter has something in common which does not change. They did not agree what it was that all things had in common, and did not experiment to find out, but used abstract reasoning rather than religion or mythology to explain themselves, thus becoming the first philosophers in the Western tradition.

Later philosophers widened their studies to include other areas of thought. The Eleatic school, for example, also studied epistemology, or how people come to know what exists. But the Ionians were the first group of philosophers that we know of, and so remain historically important.

Thales

Thales (Greek: Θαλης) of Miletus (ca. 624 BCE - 546 BCE) is listed in most History of Philosophy books as the earliest western philosopher. Before Thales, the Greeks explained the origin and nature of the world through myths of anthropomorphic gods and heroes. Phenomena like lightning or earthquakes were attributed to actions of the gods. By contrast, Thales attempted to find naturalistic explanations of the world, without reference to the supernatural. He explained earthquakes by imagining that the Earth floats on water, and that earthquakes occur when the Earth is rocked by waves. Thales' most famous belief was his cosmological doctrine, which held that the world originated from water.

Anaximander

Anaximander (Greek: Άναξίμανδρος) (610 BCE – ca. 546 BCE) has a reputation which is due mainly to a cosmological work, little of which remains. From the few extant fragments, we learn that he believed the beginning or first principle (arche, a word first found in Anaximander's writings, and which he probably invented) is an endless, unlimited mass (apeiron), subject to neither old age nor decay, which perpetually yields fresh materials from which everything we can perceive is derived.

Anaximenes

Anaximenes (Greek: Άναξιμένης) of Miletus (585 BCE - 528 BCE) held that the air, with its variety of contents, its universal presence, its vague associations in popular fancy with the phenomena of life and growth, is the source of all that exists. Everything is air at different degrees of density, and under the influence of heat, which expands, and of cold, which contracts its volume, it gives rise to the several phases of existence. The process is gradual, and takes place in two directions, as heat or cold predominates. In this way was formed a broad disk of earth, floating on the circumambient air. Similar condensations produced the sun and stars; and the flaming state of these bodies is due to the velocity of their motions.

Heraclitus

Heraclitus (Greek: Ἡράκλειτος) of Ephesus (ca. 535 - 475 BCE) disagreed with Thales, Anaximander, and Pythagoras about the nature of the ultimate substance and claimed instead that everything is derived from the Greek classical element fire, rather than from air, water, or earth. This led to the belief that change is real, and stability illusory. For Heraclitus "Everything flows, nothing stands still." He is also famous for saying: "No man can cross the same river twice, because neither the man nor the river are the same."

Empedocles

Empedocles (ca. 490 BCE – ca. 430 BCE)was a citizen of Agrigentum, a Greek colony in Sicily. Empedocles' philosophy is best known for being the origin of the cosmogenic theory of the four classical elements. He maintained that all matter is made up of four elements: water, earth, air and fire. Empedocles postulated something called Love (philia) to explain the attraction of different forms of matter, and of something called Strife (neikos) to account for their separation. He was also one of the first people to state the theory that light travels at a finite (although very large) speed, a theory that gained acceptance only much later.

Diogenes Apolloniates

Diogenes Apolloniates (ca. 460 BCE) was a native of Apollonia in Crete. Like Anaximenes, he believed air to be the one source of all being, and all other substances to be derived from it by condensation and rarefaction. His chief advance upon the doctrines of Anaximenes is that he asserted air, the primal force, to be possessed of intelligence—"the air which stirred within him not only prompted, but instructed. The air as the origin of all things is necessarily an eternal, imperishable substance, but as soul it is also necessarily endowed with consciousness."

Archelaus

Archelaus was a Greek philosopher of the 5th century BCE, born probably in Athens, though Diogenes Laërtius (ii. 16) says in Miletus. He was a pupil of Anaxagoras, and is said by Ion of Chios (Diogenes Laërtius, ii. 23) to have been the teacher of Socrates. Some argue that this is probably only an attempt to connect Socrates with the Ionian School; others (e.g. Gomperz, Greek Thinkers) uphold the story. There is similar difference of opinion as regards the statement that Archelaus formulated certain ethical doctrines. In general, he followed Anaxagoras, but in his cosmology he went back to the earlier Ionians.

Hippo

Hippo (or Hippon) was a Greek philosopher of the 5th century BCE. Very little is known about him. He held that water was the principle of all things, with fire springing from water, and then developing itself by generating the universe. Primarily interested in biological matters, he was said to have been an atheist.
