Thales of Miletus (c. 620 B.C.E.—c. 546 B.C.E.) The ancient Greek philosopher Thales was born in Miletus in Greek Ionia. Aristotle, the major source for Thales’s philosophy and science, identified Thales as the first person to investigate the basic principles, the question of the originating substances of matter and, therefore, as the founder of the school of natural philosophy. Thales was interested in almost everything,

Mind and the Causal Exclusion Problem The causal exclusion problem is an objection to nonreductive physicalist models of mental causation.

Material Composition A material composite object is an object composed of two or more material parts. The world, it seems, is simply awash with such things. The Eiffel Tower, for instance, is composed of iron girders, nuts and bolts, and so on. You and I, as human beings, are composed of flesh and bone, and various organs. Moreover, these parts themselves are composed of further

Thrasymachus (fl. 427 B.C.E.) Thrasymachus of Chalcedon is one of several “older sophists” (including Antiphon, Critias, Hippias, Gorgias, and Protagoras) who became famous in Athens during the fifth century B.C.E. We know that Thrasymachus was born in Chalcedon, a colony of Megara in Bithynia, and that he had distinguished himself as a teacher of rhetoric and speechwriter in Athens by the year 427. Beyond this,
