"If mind/subjectivity weren't a natural feature of the cosmos, then the mind-dependence of value might indeed impugn its status. Yet mind is as much a part of the natural world as are atoms and molecules. The "subjectivity" of value no more threatens its reality than the "subjectivity" of pain makes surgical anaesthetics redundant. For sure, it's all in the mind. But minds are all in the world."
