Wittgenstein

Potentially only because I like so much to say his name...
The whole sense of the book might be summed up in the following words: what can be said at all can be said clearly, and what we cannot talk about we must pass over in silence. 
Ludwig Wittgenstein
I have a bad habit of being surprised or moved by some experience, and then needing it to share it with all at hand, despite the fact that generally, it's something I "cannot talk about".
