Perhaps the essense of this contribution is that it marks an awaken- ing in mankind the desire to investigate the universe on a non-religious basis, to “model” the universe and to derive conclusions from the model. There would be many models considered, studies, and rejected before our contemporary one. So the new task of philosophers was to estab- lish what exactly provided this unity: one said it was water; another, the Boundless; yet another, air. (The goal is, of course, the quest for rational understanding of the world. Answering “The Big Questions” is the most difficult.))
Thales is believed to have been the teacher of Anaximander; he is the first natural philosopher in the Ionian (Milesian) School. According Anaximander of Miletus (mid-6th century), the word apeiron meant un- bounded, infinite, indefinite, or undefined. Originally used to reference the unlimited and that which preceded the separation into contrasting qualities, such as hot and cold, wet and dry, it thus represented the primitive unity of all phenomena. Thus, for the Greeks, the original chaos out of which the world was formed was apeiron. Evidence exists that he wrote treatises on geography, astronomy, and cosmology that survived for several centuries. He is also said to have made a map of the known world. A rationalist, he prized symmetry and introduced geometry and mathematical proportions into his efforts to map the heav- ens, a tradition that has continued throughout history. We may conclude that his theories departed from earlier, mystical models of the universe and anticipated the achievements of later astronomers.
Continuing on a linear path from Thales, Anaximander’s successor, Anaximenes of Miletus (second half of the 6th century), taught that air was the origin of all things. Anaximenes, supplementing the theories of Thales and Anaximander specified the way in which the other things arose out of the water or apeiron. He claimed that the other types of matter arose out of air by condensation and rarefaction. In this way, we see another building block in the development complete model, that of the explanation of phenomena, and this remained essentially the same through all of its transmutations.
