”The wishes and the selfishness of the individual must appear as nothing and submit,” declares Hitler in Mein Kampf; a man must “renounce putting forward his personal opinion and interests and sacrifice both.” (Leonard Peikoff, The Ominous Parallels, p.68)
That Hitler was against selfishness should not come as a surprise. He wanted to control people, and you can`t control selfish people because selfish people follow their own mind instead of obeying a dictator.
Do yourself and society a favour: be selfish!
