The Presocratic Philosophers

A presentation of the pre-socratic philosophers: Thales of Miletus: Considered the first philosopher in the Greek tradition, Thales proposed that water was the origin of all matter. Anaximander: A contemporary of Thales, he developed the concept of the apeiron, or the "unlimited," as the fundamental substance of the universe. Anaximenes: Also from Miletus, he suggested that air was the primary substance that could be transformed into other elements. Pythagoras: Known for his contributions to mathematics and his belief in the transmigration of souls, Pythagoras founded a school that influenced many later philosophers. Xenophanes: Criticized the anthropomorphic views of the gods and proposed that there is only one god, who is the mind of all things. Heraclitus: Famous for his doctrine of change, expressed in the maxim "You cannot step into the same river twice". Parmenides: Argued that reality is unchanging and that change is an illusion, influencing later philosophers like Plato. Empedocles: Proposed the theory of the four classical elements (earth, water, air, and fire) and the forces of love and strife. Democritus: Known for his atomic theory, which posited that the universe is made up of indivisible particles called atoms.
