| Courage, the footstool of the Virtues, upon which they stand. |
| Courage is a moral quality; it is not a chance gift of nature like an aptitude for games. It is a cold choice between two alternatives. |
| Next to ingratitude, the most painful thing to bear is gratitude. |
| Virtue is the music of the soul, the harmony of the passions. |
| Virtue is like a rich stone, best plain set. |
| It is the province of knowledge to speak and it is the privilege of wisdom to listen. |
| Knowledge and timber shouldn't be much used till they are seasoned. |
| Every judgment teeters on the brink of error. To claim absolute knowledge is to become monstrous. |
| Knowledge is an unending adventure at the edge of uncertainty. |
| The grain of real knowledge is concealed in a vast deal of esoteric chaff. |
