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:

History

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: "" – "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.

Aphorisms are distinct from axioms: aphorisms generally originate from experience and custom, whereas axioms are self-evident truths and therefore require no additional proof. Aphorisms have been especially used in subjects to which no methodical or scientific treatment was originally applied, such as agriculture, medicine, jurisprudence, and politics.

Society

Many societies have traditional sages or culture heroes to whom aphorisms are commonly attributed, such as the Seven Sages of Greece, Chanakya, Confucius, or King Solomon.

Misquoted or misadvised aphorisms are frequently used as a source of humour; for instance, wordplays of aphorisms appear in the works of P. G. Wodehouse, Terry Pratchett, and Douglas Adams. Aphorisms being misquoted by sports players, coaches, and commentators form the basis of Private Eye's Colemanballs section.

Philosophy

Professor of Humanities Andrew Hui, author of A Theory of the Aphorism offered the following definition of an aphorism: "a short saying that requires interpretation".
