a man possessed with peace is always smiling

I have to lie, if I don't want to take madmen seriously and become a madman myself

I am not worthy of my suffering. A great sentence. It suggests not only that suffering is the basis of the self, its sole indubitable ontological proof, but also that it is the one feeling most worthy of respect; the value of all values.

Aesthetic racism is almost always a sign of inexperience. Those who have not made their way far enough into the world of amorous delights judge women only by what can be seen. But those who really know women understand that the eye reveals only a minute fraction of what a woman can offer us. When God bade mankind be fruitful and multiply, Doctor, He was thinking of the ugly as well as of the beautiful. I am convinced I might add, that the aesthetic criterion does not come from God but from the devil. In paradise no distinction was made between ugliness and beauty.

Jealousy isn't a pleasant quality, but if it isn't overdone (and if it's combined with modesty), apart from its inconvenience there's even something touching about it.
