Theory of justification is a part of epistemology that attempts to understand the justification of propositions and beliefs. Epistemologists are concerned with various epistemic features of belief, which include the ideas of justification, warrant, rationality, and probability. Of these four terms, the term that has been most widely used and discussed by the early 21st century is "warrant". Loosely speaking, justification is the reason why someone (properly) holds the belief, the explanation as to why the belief is a true one, or an account of how one knows what one knows.
If A makes a claim, and B then casts doubt on it, A's next move would normally be to provide justification. Empiricism (the evidence of the senses), authoritative testimony (the appeal to criteria and authority), and logical deduction are often involved in justification.
Justification based theories of knowledge can be divided into:
- irrationalism, which appeals to irrational criteria and authorities (feelings) and
- panrationalism, which appeals to rational criteria and authorities (observation, reasoning).

“Hygiene is the corruption of medicine by morality. It is impossible to find a hygienest who does not debase his theory of the healthful with a theory of the virtuous.... The true aim of medicine is not to make men virtuous; it is to safeguard and rescue them from the consequences of their vices.”
—H.L. (Henry Lewis)
