I am convinced that a person doesn’t only love himself in others; he also hates himself in others.

Lichtenberg’s aphorism turns the familiar idea of projection in a darker direction. We often recognize ourselves in others and respond with affection when we see traits we value; but the same mechanism can produce aversion when another person mirrors what we dislike or fear in ourselves. The line suggests that interpersonal hostility is frequently self-directed emotion displaced outward—an ethical warning as well as a psychological insight. It implies that self-knowledge and self-acceptance can temper judgment of others, while unresolved self-contempt can make social life a theater for internal conflict.
