This sin, so far as it has lain in my power, I have endeavoured to avoid ever since I have enjoyed the faculty of reason; and if I am unable to requite good deeds that have been done me by other deeds, I substitute the desire to do so; and if that be not enough I make them known publicly; for he who declares and makes known the good deeds done to him would repay them by others if it were in his power, and for the most part those who receive are the inferiors of those who give. Thus, God is superior to all because he is the supreme giver, and the offerings of man fall short by an infinite distance of being a full return for the gifts of God; but gratitude in some degree makes up for this deficiency and shortcoming.
Este pecado, en cuanto me ha sido posible, he procurado yo huir desde el instante que tuve uso de razón; y si no puedo pagar las buenas obras que me hacen con otras obras, pongo en su lugar los deseos de hacerlas, y cuando éstos no bastan, las publico; porque quien dice y publica las buenas obras que recibe, también las recompensara con otras, si pudiera; porque, por la mayor parte, los que reciben son inferiores a los que dan; y así, es Dios sobre todos, porque es dador sobre todos y no pueden corresponder las dádivas del hombre a las de Dios con igualdad, por infinita distancia; y esta estrecheza y cortedad, en cierto modo, la suple el agradecimiento.
