# Quote — Ludwig Wittgenstein, Tractatus Logico-Philosophicus

> The aim of the book is to set a limit to thought, or rather — not to thought, but to the expression of thoughts: for in order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought).
>
> It will therefore only be in language that the limit can be set, and what lies on the other side of the limit will simply be nonsense.
