There are very many people who read simply to prevent themselves from thinking.

Everyone is a genius at least once a year.

He who is in love with himself has at least this advantage - he won't encounter many rivals.

I am confident of my ability to demonstrate that one can sometimes believe in something and yet not believe in it. Nothing is less fathomable than the systems that motivate our actions.

One is rarely an impulsive innovator after the age of sixty, but one can still be a very fine orderly and inventive thinker. One rarely procreates children at that age, but one is all the more skilled at educating those who have already been procreated, and education is procreation of another kind.

He who is enamored of himself will at least have the advantage of being inconvenienced by few rivals.

What we have to discover for ourselves leaves behind in our mind a pathway that can be used on another occasion.
