"Ludwig Wittgenstein"の名言

Logic pervades the world; the limits of the world are also the limits of logic.

The world of those who are happy is different from the world of those who are not.

I don't know why we are here, but I'm pretty sure that it is not in order to enjoy ourselves.

We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all.

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

Whereof one cannot speak, thereof one must be silent.

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

I am my world.

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.

Not how the world is, but that it is, is the mystery.

How small a thought it takes to fill a life.

Don't think, but look! (PI 66)

Our craving for generality has [as one] source … our preoccupation with the method of science. I mean the method of reducing the explanation of natural phenomena to the smallest possible number of primitive natural laws; and, in mathematics, of unifying the treatment of different topics by using a generalization. Philosophers constantly see the method of science before their eyes, and are irresistibly tempted to ask and answer in the way science does. This tendency is the real source of metaphysics, and leads the philosopher into complete darkness. I want to say here that it can never be our job to reduce anything to anything, or to explain anything. Philosophy really is “purely descriptive.

An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it.

Everything that can be thought at all can be thought clearly. Everything that can be said can be said clearly.

6.4311 Der Tod ist kein Ereignis des Lebens. Den Tod erlebt man nicht. Wenn man unter Ewigkeit nicht unendliche Zeitdauer, sondern Unzeitlichkeit versteht, dann lebt der ewig, der in der Gegenwart lebt. Unser Leben ist ebenso endlos, wie unser Gesichtsfeld grenzenlos ist. 6.4311 Death is not an event of life. Death is not lived through. If by eternity is understood not endless temporal duration but timelessness, then he lives eternally who lives in the present. Our life is endless in the way that our visual field is without limit.

Language disguises thought.
