In my opinion, epistemology is beginning with question that `human is learning a novelty, or just perception that already knew.` As I mentioned before, Epistemologies have historically tried to tell us something about the kinds of knowledge that there are. Most epistemologists, for example, have drawn a major distinction between empirical knowledge and a priori knowledge. The effort to find answers to these questions have been conducted. A study of perception already existed when Greek or medieval times, but it became priority subject on philosophy, especially Loch age. Opinion of origin of perception has two ways which is rationalism and empiricism. Rationalism developed in Europe, and empiricism delopved in England when modern age. The method of get knowledge, and about the essence of perception is divided in two ways which are idealism that object of perception and realism that actual object.
Empiricism means that stress knowledge from experience of sense. In addition, empiricism is wild spread perspective out of human`s knowledge that known as epistemology. Empiricism emphasizes the role of experience and evidence, especially sensory perception. So, empiricists think that all knowledge is of empirical, and denied the existence of any a priori knowledge.
