The most aggravating thing about the younger generation is that I no longer belong to it.

The normal objective of my thought affords no insight into the dark places of human will and feeling.

There are few enough people with sufficient independence to see the weaknesses and follies of their contemporaries and remain themselves untouched by them.

A hundred times every day I remind myself that my inner and outer life are based on the labors of others.

If I had it [life] to do all over again, I'd have been a plumber.

The supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a simple datum of experience.

All that's different about me is that I still ask the questions most people stopped asking at age five.
