Aphorism is from a Greek word and means to define. It is generally a one-liner used tersely to convey a perspective in a way that once bitten by it you are seldom likely to forget it in a hurry.
Some examples of Aphorism are as follows:
* People who live in glass houses shouldn't throw stones at others - Anon
* "Death with dignity is better than life with humiliation." -Husayn ibn Ali
* Love your mistakes but don't marry one. - Leonid Sukhorukov,
book 'All About Everything'
* Marry in haste: Repent at leisure. -- Scottish proverb
* Better to light a candle than to curse the darkness. -- Chinese Proverb.
* One man's meat is another man's poison.
Hippocrates was the first to use them to improve a way to remember symptoms to cure diseases. Later others started using them in their work. Usage of Aphorism comes from experience.
The first aphorism used by him runs as follows: --"Life is short, art is long, opportunity fugitive, experimenting dangerous, reasoning difficult: it is necessary not only to do oneself what is right, but also to be seconded by the patient, by those who attend him, by external circumstances."
