Answer: It is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It is concerned with the following aspects:
What is knowledge?
How is knowledge acquired?
What do people know?
How do we know what we know?
This field is focused on analysing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as scepticism about different knowledge claims. The term was introduced into English by the Scottish philosopher James Frederick Ferrier (1808–1864).
