When the end comes, you will be esteemed by the world and rewarded by God, not because you have won the love and respect of the princes of the earth, however powerful, but rather for having loved, defended and cherished one such as I … what you receive from others is a testimony to their virtue; but all that you do for others is the sign and clear indication of your own.

Dedication. - On the Infinite Universe and Worlds (1584)
