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

Logic pervades the world: the limits of the world are also its limits. So we cannot say in logic, "The world has this in it, and this, but not that." For that would appear to presuppose that we were excluding certain possibilities, and this cannot be the case, since it would require that logic should go beyond the limits of the world; for only in that way could it view those limits from the other side as well. We cannot think what we cannot think; so what we cannot think we cannot say either. (5.61)

There are men who are too fragile to shatter. I belong to them too.

What stands fast does so, not because it is intrinsically obvious or convincing; it is rather held fast by what lies around it.
