Humanity is never more sphinxlike than when it is expressing itself.
Humanity is acquiring all the right technology for all the wrong reasons.
Humanity either makes, or breeds, or tolerates all its afflictions.
Humanity is the virtue of a woman, generosity that of a man.
Humanity must perforce prey upon itself, like monsters of the deep.

Whatever one man does, it is as if all men did it. For that reason, it is not unfair that one disobedience in a garden should contaminate all humanity; for that reason it is not unjust that the crucifixion of a single Jew should be sufficient to save it.
In abstract love of humanity one almost always only loves oneself.
Humanity can live without science, it can live without bread, but it cannot live without beauty. Without beauty, there would be nothing left to do in this life. Here the secret lies. Here lies the entire story.

People are of two types: they are either your brothers in faith or your equals in humanity.
The greatest way to live with honor in this world is to be what we pretend to be.
