In a nutshell:
Major ideas in the Socratic philosophy were:
1. THE PROPER STUDY OF PHILOSOPHY IS MAN. Socrates was not concerned with metaphysical questions as such. He believed that philosophy should achieve practical results in the form of greater well-being for man the individual and for mankind as a society. Hence, the proper study of philosophy is man. In pursuit of this study, Socrates’ interests were centered in ethics and politics.
2. NATURAL ETHIC. Socrates attempted to establish an ethical system based upon human reason rather than upon theological directives.
3. KNOWLEDGE AND WISDOM. Socrates asserted that the highest good for any human being is happiness. Whatever action a man chooses is motivated by his desire for happiness. Knowledge, virtue, and wisdom are all the same, since man chooses an action according to what he thinks will bring him the greatest happiness. Therefore the more a man knows, the greater his ability to reason out the correct choice and to choose those actions which truly bring happiness to him.
4. SELF-KNOWLEDGE. The highest knowledge is possessed by that individual who truly knows himself. This knowledge constitutes ultimate wisdom. It enables man to act in a virtuous manner at all times, because he knows what will bring him true happiness.
5. POLITICS. Socrates did not approve of tyranny or of democracy. He believed that the best form of government was one ruled by an individual possessing the greatest ability, knowledge, and virtue. ”
