Sometimes, in doing philosophy, one just wants to utter an inarticulate sound.

Architecture immortalizes and glorifies something. Hence there can be no architecture where there is nothing to glorify.

Mathematics is a logical method. . . . Mathematical propositions express no thoughts. In life it is never a mathematical proposition which we need, but we use mathematical propositions only in order to infer from propositions which do not belong to mathematics to others which equally do not belong to mathematics.

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. And if I am not mistaken in this belief, then the second thing in which the value of this work consists is that it shows how little is achieved when these problems are solved.

A serious and good philosophical work could be written consisting entirely of jokes.
