Epistemology

Epistemology, the philosophical study of the nature, origin, and limits of human knowledge. The term is derived from the Greek epistm ("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 continuing to the present. Along with metaphysics, logic, and ethics, it is one of the four main branches of philosophy, and nearly every great philosopher has contributed to it.

Empiricism is a flow in philosophy which states that all knowledge comes from human experience. Empiricism rejects the notion that humans have brought about the nature of knowledge in themselves at birth. empiricism was born in England with its three exponents are David Hume, George Berkeley and John Locke. The teachings of empiricism give balance to science and religion in modern-day philosophy, so that it can be assumed to play down the role of reason. the term empiricism itself comes from the Greek empeirinyang which means trial or experience. As a doctrine, empiricism is the opposite of rationalism.
