Great Philosophere
The next great philosopher Socrates was. He does not worry about issues like what is the fundamental principle underlying the nature? His concern was social and ethical. His disciple, Plato is one of the greatest philosophers of all time. His view was spiritualistic and he was opposed to the philosophy and natural sciences. For him, nature is very corrupt and unreal. So his point of view instead of promoting science hindered its progress. His disciple Aristotle was much more interested in natural sciences. He became one of the greatest philosophers and scientists that the world had produced. According to him, nature is composed of two principles, the substance and form. Shape is responsible for change and the question is inert substance is composed of five elements, earth, water, fire, air and others. The documents that are on the earth are composed of four elements of the first and celestial bodies and the fifth only. Aristotle introduced the doctrine of the causes of changes in its physical wok, Physics.

Aristotle ended reflection on the nature of ultimate principle underlying nature. Aristotle's natural philosophy has dominated the Western scientific tradition in the 17th century. Therefore, it may be said that the tradition of natural philosophy of Greece began with Thales and ended with Aristole. It is this tradition of natural philosophy that science owes its Greek character.
