world as will and representation

is, in other words, the world as subjectively and objectively apprehended.

So along these lines, Schopenhauer's pessimistic vision of the world can itself be seen to be grounded upon the subject-object distinction, i.e., the general root of the principle of sufficient reason. As mentioned above, we can see this fundamental reliance upon the subject-object distinction reflected in the very title of his book, The World as Will and Representation, which can be read as, in effect, The World as Subjectively and Objectively Apprehended.
