The first known use of aphorism was in 1528.
Where did aphorisms come from?
Aphorisms almost always come from life experience. They're passed on from someone who's “walked the walk.” These aphorisms are general remarks on life: the good, the bad, and the ugly.
Where are aphorisms found?
Aphorisms are widely found in literature. In fact, many aphorisms used in literature break through their literary use and become relevant in their own sense, apart from the original work in which they appeared. Many are used in everyday conversation due to their catchy and witty word choice.
