Logic takes care of itself; all we have to do is to look and see how it does it. - Ludwig Wittgenstein

What makes a subject difficult to understand — if it is significant, important — is not that some special instruction about abstruse things is necessary to understand it. Rather it is the contrast between the understanding of the subject and what most people want to see. Because of this the very things that are most obvious can become the most difficult to understand. What has to be overcome is not difficulty of the intellect but of the will. [Nicht eine Schwierigkeit des Verstandes, sondern des Willens ist zu überwinden.]

a nothing will serve just as well as a something about which nothing could be said.

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