I can imagine no greater catastrophe than if I were mistaken, and the theory were correct that what I consider secondary instincts or drives are actually primary instincts! Because in that case the emotional plague would rest upon the support of a natural law while its archenemies, truth and sociality, would be relying upon unfounded ethics. Until now both lies and truth have taken recourse to ethics. But only lies have profited because they were able to appear under the guise of truth. Under these circumstances, egoism, theft, petty selfishness, slander, etc., would be the natural rule. (26.July.1943)
