A nation that draws too broad a difference between its scholars and its warriors will have its thinking done by cowards, and its fighting done by fools.
The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding, go out to meet it.
The sufferings that fate inflicts on us should be borne with patience, what enemies inflict with manly courage.
Self-control is the chief element in self-respect and self-respect is the chief element in courage.
