Quote from ‘Short Logic: Chapter I. Of Reasoning in General’
A Belief is a state of mind of the nature of a habit, of which the person is aware, and which, if he acts deliberately on a suitable occasion, would induce him to act in a way different from what he might act in the absence of such habit.
[—] If a man really believes that alcohol is injurious to him and does not choose to injure himself, but still drinks for the sake of the momentary satisfaction, then he is not acting deliberately. But a habit of which we are not aware, or with which we are not deliberately satisfied, is not a belief.
An act of consciousness in which a person thinks he recognizes a belief is called a judgement. The expression of a judgement is called in logic a proposition.
