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.

While the State exists, there can be no freedom. When there is freedom there will be no State.
A lie told often enough becomes the truth.
Be as radical as reality.
