I find myself hoping a total end of all the unhappy divisions of mankind by party-spirit, which at best is but the madness of many for the gain of a few.
The proper study of Mankind is Man.

We consider Christmas as the encounter, the great encounter, the historical encounter, the decisive encounter, between God and mankind. He who has faith knows this truly; let him rejoice.
You must strive to multiply bread so that it suffices for the tables of mankind, and not rather favor an artificial control of birth, which would be irrational, in order to diminish the number of guests at the banquet of life.
