…the majority of men do not think in order to know the truth, but in order to assure themselves that the life which they lead, and which is agreeable and habitual to them, is the one which coincides with the truth.

I believe that order is better than chaos, creation better than destruction. I prefer gentleness to violence, forgiveness to vendetta. On the whole I think knowledge is preferable to ignorance, and I am sure human sympathy is more valuable than ideology.

The example of a syllogism that he had studied in Kiesewetter's logic: Caius is a man, men are mortal, therefore Caius is mortal, had throughout his whole life seemed to him right only in relation to Caius, but not to him at all.

Our body is a machine for living. It is organized for that, it is its nature. Let life go on in it unhindered and let it defend itself.

Love those you hate you.

A man's every action is inevitably conditioned by what surrounds him and by his own body.

Is it possible to say what one really feels?
