In Plato’s Theaetetus, Socrates examines the first definition of knowledge that theaetetus gives that knowledge is perception. Socrates gives us many example that both supports and refutes that knowledge is perception. The basic claim from Protagoras is that truth is based on the perception of every man. This means that things are to any person as they seem to that person. Socrates explains to us Protagoras’s view with the cold wind example. He say that through Protagoras theory, the wind is cold to the person that feels cold, and the wind is warm to the person that feels warm. Both “the wind is cold” and “the wind is war” is true according to Protagoras and it is based on the perception of the person. Then we learn from Socrates that if knowledge and truth is based on perception then everything that has perception has his own set of knowledge and truth. Also sense Protagoras not considering himself to be a god, and is on the same level of us then wouldn’t the truth and knowledge he definite in his doctrine only be his own set truth and knowledge for he only knows his own perspective.
He then go on to giving us the theory of flux by Heraclitus. The theory of flux is based on the claim that all things are constantly changing. The view is that no objects is stably consistent with stably existing properties. The explanation for this is that everything in which any basis can be functional, according to one perception, can also have the cancelation of that basis applied to it, according to an opposite perception. Socrates gives us a few statements that Heraclitus implies with his theory. The first is that all qualities do not exist in time or space independently. The second is that qualities do not exist except in perception of the...
