Aphorism

An aphorism (from Greek ἀφορισμός: aphorismos, denoting 'delimitation', 'distinction', and 'definition') is a concise, terse, laconic, or memorable expression of a general truth or principle. Aphorisms are often handed down by tradition from generation to generation.

The concept is generally distinct from those of an adage, brocard, chiasmus, epigram, maxim (legal or philosophical), principle, proverb, and saying; although some of these concepts could be construed as types of aphorism.

Often aphorisms are distinguished from other short sayings by the need for interpretation to make sense of them. In A Theory of the Aphorism, Andrew Hui defined an aphorism as "a short saying that requires interpretation".

A famous example is:

You cannot step into the same river twice.

— Heraclitus

The word was first used in the Aphorisms of Hippocrates, a long series of propositions concerning the symptoms and diagnosis of disease and the art of healing and medicine. The often-cited first sentence of this work is: "Ὁ βίος βραχύς, δὲ τέχνη μακρή" – "life is short, art is long", usually reversed in order (Ars longa, vita brevis).

This aphorism was later applied or adapted to physical science and then morphed into multifarious aphorisms of philosophy, morality, and literature. Currently, an aphorism is generally understood to be a concise and eloquent statement of truth.
