It would truly be a fine thing if men suffered themselves to be guided by reason, that they should acquiesce in the true remonstrances addressed to them by the writings of the learned and the advice of friends. But the greater part are so disposed that the words which enter by one ear do incontinently go out of the other, and begin again by following the custom. The best teacher one can have is necessity.
The bravery founded on hope of recompense, fear of punishment, experience of success, on rage, or on ignorance of danger, is but common bravery, and does not deserve the name. True bravery proposes a just end; measures the dangers, and meets the result with calmness and unyielding decision.
