“Mankind is unkind, man.”
“The noblest study of mankind is Man, says Man.”
“How frequently has melancholy and even misanthropy taken possession of me, when the world has disgusted me, and friends have proven unkind. I have then considered myself as a particle broken off from the grand mass of mankind.”
“They say: 'If a man knew himself,he would know all mankind.'I say: 'If a man loved mankind,he would know something of himself.”
“I love mankind, he said, "but I find to my amazement that the more I love mankind as a whole, the less I love man in particular.”
“That's one small step for a man, one giant leap for mankind”
