Suffering, Asceticsim, Oblivion

In #68 of World as Will and Representation, in the context of an exposition of Asceticism, Schopenhauer asserts that "With the complete abolition of knowledge the rest of the world would of itself also vanish into nothing, for there can be no object without a subject."  The key words in this statement are "also" and "world".  For, the former implies that the subject, as well, would vanish into nothing, while the latter is not qualified either as 'Will' or as 'Representation'.  So, with this assertion, Schopenhauer, perhaps unwittingly in the context, is promoting Oblivion, not Asceticism as the solution to suffering.  The conflation here is not incidental--in its diagnosis of suffering, his system vacillates between attributing it to the individuation that is the product of the severing of subject from object in Representation, and to the incessant striving of Will.  The ambiguity of 'world' in the assertion epitomizes that fundamental incoherence in his system.
