The names of great painters are like passing-bells: in the name of Velasquez you hear sounded the fall of Spain; .in the name of Titian, that of Venice; in the name of Leonardo, that of Milan; in the name of Raphael, that of Rome. And there is profound justice in this, for in proportion to the nobleness of the power is the guilt of its use for purposes vain or vile; and hitherto the greater the art, the more surely has it been used, and used solely, for the decoration of pride or the provoking of sensuality.

All great art is the expression of man's delight in God's work, not his own.

All great art is the work of the whole living creature, body and soul, and chiefly of the soul.

One who does not know when to die, does not know how to live.

The truth of Nature is a part of the truth of God; to him who does not search it out, darkness; to him who does, infinity.

It is his restraint that is honorable to a person, not their liberty.

You will find that the mere resolve not to be useless, and the honest desire to help other people, will, in the quickest and delicatest ways, improve yourself.
