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

It is obvious that an imagined #‎ world , however different it may be from the real one, must have something - a form - in common with it.

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

In order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought).

A philosophical problem has the form: I don't know my way about.

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.

The world of the happy is quite different from that of the unhappy.
