Silence is the genius of fools and one of the virtues of the wise

The true genius shudders at incompleteness — imperfection — and usually prefers silence to saying the something which is not everything that should be said.

The most tragic thing in the world is a man of genius who is not a man of honor.

A genius can't be forced; nor can you make an ape an alderman.

Genius is intensity

Nothing more advances authority than silence.
