The most significant theories of Socrates include the theory of value, theory of knowledge, theory of human nature, theory of learning, theory of transmission, theory of society, theory of opportunity and theory of consensus. Socrates was an ancient Greek philosopher who lived in the fifth century BC, often regarded as one of the greatest philosophers in history.
According to Socrates' theory of knowledge, human knowledge can be divided into ordinary and higher knowledge. The theory of human nature states that every human being is an inner-self, whereas the theory of learning requires seeking truth in all matters. Socrates believed that no person or school has the wisdom to teach others, an idea that is the basis of his theory of transmission.
