This movement towards rationality and argumentation would pave the way for the course of Western thought. Aristotle offers some conjectures as to why Thales might have believed this (Graham 29).First, all things seem to derive nourishment from moisture.How it is that this separation took place is unclear, but we might presume that it happened via the natural force of the boundless.The universe, though, is a continual play of elements separating and combining.Unlike Anaximander, Anaximenes made this boundless thing something definite—air.For Anaximander, hot and cold separated off from the boundless, and these generated other natural phenomena (Graham 79). Both Cicero and Aetius report that, for Anaximenes, air is God (Graham 87). E.) directly and explicitly challenged Homeric and Hesiodic mythology.We find proto-scientific explanations of the natural world in the Milesian thinkers, and we hear Democritus posit atoms—indivisible and invisible units—as the basic stuff of all matter.
Like Anaximander, Anaximenes thought that there was something boundless that underlies all other things.
He might have thought that, since the other elements seem more or less to change into one another, there must be some source beyond all these—a kind of background upon or source from which all these changes happen.
Indeed, this everlasting principle gave rise to the cosmos by generating hot and cold, each of which “separated off” from the boundless.
In poetic fashion, Anaximander says that the boundless is the source of beings, and that into which they perish, “according to what must be: for they give recompense and pay restitution to each other for their injustice according to the ordering of time” (F1).
If our dates are approximately correct, Anaximenes (c.546-c.528/5 B. E.) could have had no direct philosophical contact with Anaximander.
