Adultery is not a crime, it’s an amusement.

Adultery is the injury of nature.

The psychology of adultery has been falsified by conventional morals, which assume, in monogamous countries, that attraction to one person cannot coexist with affection for another. Everybody knows that this is untrue.

Adultery is an evil only inasmuch as it is a theft; but we do not steal that which is given to us.

The Devil did not tempt Adam and Eve to steal, to lie, to kill, to commit adultery; he tempted them to live independent of God.

Nothing optional — from homosexuality to adultery — is ever made punishable unless those who do the prohibiting (and exact the fierce punishment) have a repressed desire to participate.
