The truth of the thoughts that are here set forth seems to me unassailable and definitive. I therefore believe myself to have found, on all essential points, the final solution of the problems.

What we cannot speak about we must pass over in silence.
No one likes having offended another person; hence everyone feels so much better if the other person doesn't show he's been offended. Nobody likes being confronted by a wounded spaniel.

No one can think a thought for me in the way that no one can don my hat for me.
If you want to go down deep you do not need to travel far; indeed, you don't have to leave your most immediate and familiar surroundings.

Suppose someone follows the series "1,3,5,7, ..", and in writing the series 2x+1; and he asked himself "But am I always doing the same thing, or something different every time?"
