The Original Phusikoi
 
Our name is derived from from the Pre-Socratics who, beginning with Thales around the 6th Century BC, were the first to apply rational thought to explaining how and why things are. The Phusikoi invented Western Science and Philosophy. They were the first to seek rational explanations of natural phenomenon rather than attributing these phenomenon to supernatural deities. The landscape of their inquiry was diverse and in modern terms would best be described as "holistic," interweaving science, philosophy, art, politics, and theology into a combined worldview. They used their own direct observations and experiences as a laboratory to investigate the nature of reality and were the first ones to devise language and methods for communicating their experiences to others in a rational manner.

Examples of Phusikoi include Pythagoras, Hericlitus, Democritus, Anaximander, Parmenides, Zeno, Empedocles, Leucippus, Anaxagoras, Xenophanes, and Diogenes to name a few.  For more information about the lives and contributions of the Phusikoi, check out these online resources:
