"According to Scheler, resentment always turns into either unscrupulous ambition or bitterness, depending on whether it is implanted in a strong person or a weak one. But in both cases it is a question of wanting to be something other than what one is. Resentment is always resentment against oneself. The rebel, on the contrary, from his very first step, refuses to allow anyone to touch what he is. He is fighting for the integrity of one part of his being."
