Epistemology, the philosophical study of the nature, origin, and limits of human knowledge. The term is derived from the Greek episteme (“knowledge”) and logos (“reason”). Along with metaphysics, logic, and ethics, it is one of the four main branches of philosophy.
Many epistemologists attempt to explain one kind of cognitive success in terms of other kinds. For instance, Chisholm tries to explain all cognitive success notions in terms of just one primitive notion: that of one attitude being more reasonable than another, for an agent at a time (see Chisholm 1966).
One family of epistemological issues about perception arises when we concern ourselves with the psychological nature of the perceptual processes through which we acquire knowledge of external objects. According to direct realism, we can acquire such knowledge because we can directly perceive such objects.

epistemology, the philosophical study of the nature, origin, and limits of human knowledge. The term is derived from the Greek epistēmē (“knowledge”) and logos (“reason”), and accordingly the field is sometimes referred to as the theory of knowledge. Epistemology has a long history within Western philosophy, beginning with the ancient Greeks and co
Why should there be a discipline such as epistemology? Aristotle (384–322 bce) provided the answer when he said that philosophy begins in a kind of wonder or puzzlement. Nearly all human beings wish to comprehend the world they live in, and many of them construct theories of various kinds to help them make sense of it. Because many aspects of the world defy easy explanation, however, most people are likely to cease their efforts at some point and to content themselves with whatever degree of understanding they have managed to achieve. Unlike most people, philosophers are captivated—some would say obsessed—by the idea of understanding the world in the most general terms possible. Accordingly, they attempt to construct theories that are synoptic, descriptively accurate, explanatorily powerful, and in all other respects rationally defensible. In doing so, they carry the process of inquiry further than other people tend to do, and this is what is meant by saying that they develop a philosophy about such matters.
