There is a certain virtue in every good man, which night and day stirs up the mind with the stimulus of glory, and reminds it that all mention of our name will not cease at the same time with our lives, but that our fame will endure to all posterity.
That he who hath the loan of money has not repaid it, and he who has repaid has not the loan; but he who has acknowledged a kindness has it still, and he who has a feeling of it has requited it.
