Common sense is the genius of mankind.

The world belongs to optimists; the pessimists are only spectators.

Nothing falsifies history more than logic.

Common sense is the genius of mankind.

The effect of great and inevitable misfortune is to elevate those souls which it does not deprive of all virtue.

It is only after an unknown number of unrecorded labors, after a host of noble hearts have succumbed in discouragement, convinced that their cause is lost; it is only then that cause triumphs.

Modesty is a shining light; it prepares the mind to receive knowledge, and the heart for truth.
