The gratitude is greater than the gift.

If you pick up a starving dog and make him prosperous, he will not bite you. This is the principal difference between a dog and a man.

I know what I have given you. I do not know what you have received.

The friend of all humanity is no friend to me.

Unfortunately, humanitarianism has been the mark of an inhuman time.

Without virtue, both riches and honor, to me, seem like the passing cloud.
