I do not believe in the God of theology who rewards good and punishes evil.

I have never belonged wholeheartedly to a country, a state, nor to a circle of friends, nor even to my own family. When I was still a rather precocious young man, I already realized most vividly the futility of the hopes and aspirations that most men pursue throughout their lives. Well-being and happiness never appeared to me as an absolute aim. I am even inclined to compare such moral aims to the ambitions of a pig.

In order to be an immaculate member of a flock of sheep, one must above all be a sheep oneself.

I think that only daring speculation can lead us further and not accumulation of facts.

Though our conduct seems so very different from that of the higher animals, the primary instincts are much alike in them and in us.

I see only with deep regret that God punishes so many of His children for their numerous stupidities, for which only He Himself can be held responsible; in my opinion, only His nonexistence could excuse Him.

I always found I was in the best of company, alone.
