“Philosophy, as we use the word, is a fight against the fascination which forms of expression exert upon us.”

“Perhaps what is inexpressible (what I find mysterious and am not able to express) is the background against which whatever I could express has its meaning.”

“Philosophy ought really to be written only as a form of poetry.”

“There is a truth in Schopenhauer’s view that philosophy is an organism, and that a book on philosophy, with a beginning and end, is a sort of contradiction. ... In philosophy matters are not simple enough for us to say ‘Let’s get a rough idea’, for we do not know the country except by knowing the connections between the roads.”

“Philosophy is a battle against the bewitchment of our intelligence by means of language.”

“The mechanism which we don't understand is not anything in our soul, but rather that of the life of this expression.”

“I am sitting with a philosopher in the garden; he says again and again 'I know that that’s a tree', pointing to a tree that is near us. Someone else arrives and hears this, and I tell him: 'This fellow isn’t insane. We are only doing philosophy.”
