“If people never did silly things nothing intelligent would ever get done.”

“Never stay up on the barren heights of cleverness, but come down into the green valleys of silliness.”

“My day passes between logic, whistling, going for walks, and being depressed. I wish to God that I were more intelligent and everything would finally become clear to me - or else that I needn’t live much longer.”

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

“We regard the photograph, the picture on our wall, as the object itself (the man, landscape, and so on) depicted there. This need not have been so. We could easily imagine people who did not have this relation to such pictures. Who, for example, would be repelled by photographs, because a face without color and even perhaps a face in reduced proportions struck them as inhuman.”

“That it doesn’t strike us at all when we look around us, move about in space, feel our own bodies, etc. etc., shows how natural these things are to us. We do not notice that we see space perspectivally or that our visual field is in some sense blurred towards the edges. It doesn’t strike us and never can strike us because it is the way we perceive. We never give it a thought and it’s impossible we should, since there is nothing that contrasts with the form of our world.What I wanted to say is it’s strange that those who ascribe reality only to things and not to our ideas move about so unquestioningly in the world as idea and never long to escape from it.”

“If you tried to doubt everything you would not get as far as doubting anything. The game of doubting itself presupposes certainty.”
