The Tractatus shows how to contemplate and apprehend the world as a limited whole trough illicitly stating formal concepts.
Wittgenstein pushes the reader into the borders of the world (because of positing the limits of language) by a methodological struggle into contemplation via his remarks. He makes a distinction between sense and nonsense, saying and showing.
In climbing up the ladder we struggle internally against presuppositions in logic. It is precisely because of the struggle we arrive at a state where we can apprehend what cannot be said but shows itself as features of our language. Part of arriving at this state is accepting that what is internal to the world (logic) is senseless. Seeing logic in this perspective demands a contemplative attitude.
Even though Wittgenstein does not directly speak on aesthetical and ethical matters, he shows how to arrive at a state where contemplation from an aesthetical and ethical attitude is possible and that is where valuation posits meaning to the world of facts.
