Ludwig Wittgenstein

How small a thought it takes to fill a life.

I am sitting with a philosopher in the garden; he says again and again 'I know that that__ a tree', pointing to a tree that is near us. Someone else arrives and hears this, and I tell him: 'This fellow isn__ insane. We are only doing philosophy.

I am my world.

The real question of life after death isn't whether or not it exists, but even if it does what problem this really solves.

Whereof one cannot speak, thereof one must be silent.

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

Man has to awaken to wonder - and so perhaps do peoples. Science is a way of sending him to sleep again.

A man will be imprisoned in a room with a door that's unlocked and opens inwards as long as it does not occur to him to pull rather than push.

Imagine a person whose memory could not retain what the word 'pain' meant__o that he constantly called different things by that name__ut nevertheless used the word in a way fitting in with the usual symptoms and presuppositions of __ain___n short he uses it as we all do. Here I should like to say: a wheel that can be turned though nothing else moves with it, is not part of the mechanism

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.

The problems are solved, not by giving new information, but by arranging what we have known since long.

It seems to me that, in every culture, I come across a chapter headed 'Wisdom.' And then I know exactly what is going to follow: 'Vanity of vanities, all is vanity.'

I think one of the things you and I have to learn is that we have to live without the consolation of belonging to a Church....Of one thing I am certain. The religion of the future will have to be extremely ascetic, and by that I don't mean just going without food and drink.

Concerning that which cannot be talked about, we should not say anything.

The logic of the world is prior to all truth and falsehood.

If you and I are to live religious lives, it mustn't be that we talk a lot about religion, but that our manner of life is different. It is my belief that only if you try to be helpful to other people will you in the end find your way to God.

The human body is the best picture of the human soul.

The world is independent of my will.
