Envy and jealousy are the private parts of the human soul. Perhaps the comparison can be extended.

The surest sign of the estrangement of the opinions of two persons is when they both say something ironical to each other and neither of them feels the irony.

A person must have a good memory to keep the promises he has made. A person must have a strong imagination to be able to have pity. So closely is morality tied to the quality of the intellect.

I condemn Christianity; I bring against the Christian Church the most terrible of all accusations that an accuser has ever had in his mouth. It is, to me, the greatest of all imaginable corruptions; it seeks to work the ultimate corruption, the worse possible corruption. The Christian Church has left nothing untouched by its depravity; it has turned every value into worthlessness, and every truth into a lie, and every integrity into baseness of soul.

Of all evil I deem you capable: therefore I want the good from you.
