In contrast to Parmenides, who based their quest for knowledge on vague imagination, philosophers before the period of Socrates derived it through experimentation. Democritus was in contrast to early Greek philosophers who were at odds regarding the truth about the outer universe.Thales, Anaxagoras and Socrates put their efforts for reformation and evolution of the discipline of philosophy.According to Plato, knowledge was the gate way for philosophy but it was not a source of happiness for one who seeks wisdom.he not only tried to solve the imaginative queries of individual but also broaden this aspect up to the ideal state and ultimate human destiny. It was Aristotle who beautified and unearthed the philosophy.It was, therefore, evident that philosophy was not subservient to knowledge but a broad discipline connecting human nature with real life.
