Almost every famous person at least once in their life said something that was remembered by the society, and considered meaningful, important or just funny. Those quotations can be mentioned in various situations. Often they are used in speeches or in a humorous way. In order to find some of them grub around.
Democritus
Date: August 22, 2009
Tis hard to fight with anger, but the prudent man keeps it under control.
Our sins are more easily remembered than our good deeds.
I would rather discover one scientific fact than become King of Persia.
Nothing exists except atoms and empty space;everything else is opinion.
Do not trust all men, but trust men of worth; the former course is silly, the latter a mark of prudence.
Word is a shadow of a deed.
The pride of youth is in strength and beauty, the pride of old age is in discretion.
