In any collaboration between two men (or groups) who hold different basic principles, it is the more evil or irrational one who wins.

The rational (principle, premise, idea, policy, or action) is that which is consonant with the facts of reality; the irrational is that which contradicts the facts and attempts to get away with it. A collaboration is a joint undertaking, a common course of action. The rational (the good) has nothing to gain from the irrational (the evil), except a share of its failures and crimes; the irrational has everything to gain from the rational: a share of its achievements and values. An industrialist does not need the help of a burglar in order to succeed; a burglar needs the industrialist’s achievement in order to exist at all. What collaboration is possible between them and to what end?
