Consider a few rules about the working of principles in practice and about the
relationship of principles to goals . . . .
In any conflict between two men (or two groups) who hold the same basic
principles, it is the more consistent one who wins.
In any collaboration between two men (or two groups) who hold different
basic principles, it is the more evil or irrational one who wins.
When opposite basic principles are clearly and openly defined, it works to
the advantage of the rational side; when they are not clearly defined, but are
hidden or evaded, it works to the advantage of the irrational side.
