As I approve of a youth that has something of the old man in him, so I am no less pleased with an old man that has something of the youth. He that follows this rule may be old in body, but can never be so in mind.
He who looks on a true friend looks, as it were, upon a kind of image of himself: wherefore friends, though absent, are still present; though in poverty, they are rich; though weak, yet in the enjoyment of health; and, what is still more difficult to assert, though dead, they are alive.
