Subsequent writers have continuously grappled with Berkeley's skeptical arguments. Immanuel Kant responded by rejecting Berkeley's immaterialism and replacing it with transcendental idealism, which views the mind-independent world as existent but incognizable in itself. From the point of view of subjective idealism, the material world does not exist, and the phenomenal world is dependent on humans. As Berkeley wrote: "for the Existence of an Idea consists in being perceived".[3] This would separate everything as objective and subjective. Subjective idealism is featured prominently in the Norwegian novel Sophie's World, in which "Sophie's world" exists in fact only in the pages of a book.[citation needed] ./cache/en-wikipedia-org-6409.html ./txt/en-wikipedia-org-6409.txt
