A big change in history, was when the scientific theory of "philosophy" was introduced, it began in Anatolia. Greek's natural philosophy sparked a new thought of how the world was created, and many other things that we still use today and call modern science. Before philosophy the Greeks believed in mythology "In ancient Greece, stories about gods and goddesses and heroes and monsters were an important part of everyday life. They explained everything from religious rituals to the weather, and they gave meaning to the world people saw around them"1.
Secular philosophy was studied by Aristotle and Plato, they explored science, logic, and literature. Pythagros studied mathematics and invented the Pythagros theorem which is a formula we still use today in geometry. Epicurus' philosophy was Skepticism and he explored the thoughts and ideas of "centrality of matter, the soul is not immortal, and if God exists he is indifferent to human affairs" 2
