6.4321 The facts all contribute only to setting the problem, not to its solution.

6.44 It is not how things are in the world that is mystical, but that it exists.

6.45 To view the world sub specie aeterni [from the viewpoint of eternity] is to view it as a whole---a limited whole.
Feeling the world as a limited whole---it is this that is mystical.

6.5 When the answer cannot be put into words, neither can the question be put into words.
The riddle does not exist.
If a question can be framed at all, it is also possible to answer it.

6.51 Scepticism is not irrefutable, but obviously nonsensical, when it tries to raise doubts where no questions can be asked.
For doubt can exist only where a question exists, a question only where an answer exists, and an answer only where something can be said.

6.52 We feel that even when all possible scientific questions have been answered, the problems of life remain completely untouched. Of course there are then no questions left, and this itself is the answer.

-- Wittgenstein, from Tractatus Logico-Philosophicus
