He founded the first University called Academy in the year 387 B.C. Platos most and best known account is Theory of Forms. He proposed that what is truly real is not the objects we encounter in our sensory experience but relatively forms, which can only be obtained logically. Platos theory of forms included allegory of the cave, divided line, platonic forms, platonic realism, division of the soul, philosopher king and memories of the soul.
Plato stated that only forms are truly real but is something that cannot be described as an object; however it can be described as a sensory experience. Aristotle was a student of Platos and teacher of Alexander the Great. He created his own school in 335 B.C. in Athens. He thought of metaphysics to be the first philosophy which formed a part of Aristotles interests. Aristotles stated that forms are universal. He created main ideas that included categories of reason, syllogism, conceptualism, accidental vs. essential properties, the four causes, hierarchy of being, the unmoved mover and types of reasoning/knowledge.
According to Aristotle, notion of Essential properties makes something what it is, and accidental properties are the differences of that item. For example, there are many different types of paper, there are small, big, pink, black, white, yellow etc. but they are still considered paper and this is what it makes it an accidental property. Aristotles believed that each thing is maintained of a mixture of both matter and form. By forms he meant essential conception of a thing and its fundamental conception.
Together Plato and Aristotle were both attracted in practically every subject and spoke wisely on topics and problems related to philosophy. They both had ideas on ways to progress the general public. Plato and Aristotle each agreed that justice exists as an objective sense, for instance, it states that a belief that a good life should be provided to everyone, including people from the future regardless of how high or low their social standings are. They both have a great impact even in todays society in political scientists.
