"With Kant, then, external reality thus drops almost totally out of the picture, and we are trapped inescapably in subjectivity—and that is why Kant is a landmark. Once reason is in principle severed from reality, one then enters a different philosophical universe altogether. This interpretive point about Kant is crucial and controversial. An analogy may help drive the point home. Suppose a thinker argued the following: 'I am an advocate of freedom for women. Options and the power to choose among them are crucial to our human dignity. And I am wholeheartedly an advocate of women’s human dignity. But we must understand that a scope of a woman’s choice is confined to the kitchen. Beyond the kitchen’s door she must not attempt to exercise choice. Within the kitchen, however, she has a whole feast of choices—whether to cook or clean, whether to cook rice or potatoes, whether to decorate in blue or yellow. She is sovereign and autonomous. And the mark of a good woman is a well-organized and tidy kitchen.' No one would mistake such a 'thinker for an advocate of woman’s freedom. Anyone would point 'out that there is a whole world beyond the kitchen and that 'freedom is essentially about exercising choice about defining and 'creating one’s place in the world as a whole. The key point about Kant, to draw the analogy crudely, is that he prohibits knowledge of anything outside our skulls. He gives reason lots to do within the skull, and he does advocate a well-organized and tidy mind, but this hardly makes him a champion of reason. The point for any advocate of reason is that there is a whole world outside our skulls, and reason is essentially about knowing it. Kant’s contemporary Moses Mendelssohn was thus prescient in identifying Kant as 'the all-destroyer.'"
