The unselective knowledge drive resembles the indiscriminate sexual drive--signs of vulgarity!

Idleness is the parent of psychology.

Once the decision has been made, close your ear even to the best counter argument: sign of a strong character. Thus an occasional will to stupidity.

The elimination of the will altogether and the switching off of the emotions all and sundry, is tantamount to the elimination of reason: intellectual castration.

One who is always deeply involved in what he is doing is above all embarrassment.

That little hypocrites and half-crazed people dare to imagine that on their account the laws of nature are constantly broken; such an enhancement of every kind of selfishness to infinity, to impudence, cannot be branded with sufficient contempt. And yet Christianity owes its triumph to this pitiable flattery of personal vanity.

The humanity of famous intellectuals lies in being wrong with gracious courtesy when dealing with those who are not famous.
