Let us be true: this is the highest maxim of art and of life, the secret of eloquence and of virtue, and of all moral authority

Let us be true: this is the highest maxim of art and of life, the secret of eloquence and of virtue, and of all moral authority.

An error is the more dangerous in proportion to the degree of truth which it contains

Truth is not only violated by falsehood; it may be equally outraged by silence

To know how to suggest is the art of teaching

We only understand that which already within us.
