How to use thing-in-itself in a sentence
As a philosopher, he is interesting for his criticism of the theory of the “thing-in-itself” (Ding-an-sich).
As thing-in-itself, the Will is exempt even from the first of the forms of knowledge, the form of being 'object for a subject.'
For the will, though the nearest we can get to the thing-in-itself, is in truth a partially phenomenalised expression of this.
On the other hand, everything as thing-in-itself is free; for 'freedom' means only non-subjection to that law.
Ultimately, freedom is a mystery, and takes us beyond even will as the name for the thing-in-itself.
