Location of "Miletus on the western coast of "Anatolia, home to Thales, Anaximander, and Anaximenes

The Milesian school was a school of thought founded in the 6th century BC. The ideas associated with it are exemplified by three "philosophers from the "Ionian town of "Miletus, on the Aegean coast of "Asia Minor: "Thales, "Anaximander, and "Anaximenes. They introduced new opinions contrary to the prevailing belief of how the world was organized, in which natural phenomena were explained solely by the will of "anthropomorphized gods. The Milesians conceived of nature in terms of methodologically observable entities, and as such was one of the first truly "scientific philosophies.

Note: It is important to make a distinction between the Milesian school and the "Ionian, which includes the philosophies of both the Milesians and other distinctly different Ionian thinkers such as "Heraclitus. See also: "Pre-Socratic philosophy.

Philosophy of nature[edit]

These "philosophers defined all things by their quintessential substance (which "Aristotle, perhaps being anachronistic,[1] called the ἀρχή / "arche)[2] of which the world was formed and which was the source of everything. "Thales thought it to be "water.[3] But as it was impossible to explain some things (such as "fire) as being composed of this "element, Anaximander chose an unobserved, undefined element, which he called "apeiron[4] (ἄπειρον "having no limit"). He reasoned that if each of the four classical "empedoclean elements ("water, "air, "fire, and "earth) are opposed to the other three, and if they cancel each other out on contact, none of them could constitute a stable, truly elementary form of matter. Consequently, there must be another entity from which the others originate, and which must truly be the most basic element of all. The notion of temporal infinity was familiar to the Greek mind in the religious conception of immortality and Anaximander's description was in terms appropriate to this conception. This arche is called "eternal and ageless" (Hippolitus I,6,I;DK B2). Critics disliked the unspecified nature of the apeiron, which caused Anaximenes to define it as being air, which is a more concrete, yet still subtle, element.[5] Anaximenes held that by its "evaporation and "condensation, air can change into other elements or substances such as fire, wind, clouds, water, and earth. However, our modern concept of "energy is much more similar to Anaximander's apeiron.

Cosmology[edit]

The differences between the three philosophers was not limited to the nature of matter. Each of them conceived of the universe differently. Thales held that the world was floating in water. Anaximander placed the world at the center of a universe composed of hollow, concentric wheels filled with fire, and pierced by holes at various intervals, which appeared as the "sun, the "moon, and the other stars. For Anaximenes, the sun and the moon were flat disks traveling around a heavenly canopy, on which the stars were fixed.
