AXIOM.

Synonym:

truism.

Both the axiom and the truism are instantly seen to be true, and need no proof; but in an axiom there is progress of thought, while the truism simply says the same thing over again, or says what is too manifest to need saying. The axiom that "things which are equal to the same thing are equal to one another" unfolds in the latter part of the sentence the truth implied in the first part, which might have been overlooked if not stated. In the truism that "a man can do all he is capable of," the former and the latter part of the sentence are simply identical, and the mind is left just where it started. Hence the axiom is valuable and useful, while the truism is weak and flat, unless the form of statement makes it striking or racy, as "all fools are out of their wits." Compare [PROVERB].
