What is more subjective is not necessarily more private. In general it is intersubjectively available. I assume that the intersubjective ideas of exp… - Thomas Nagel

I am not adverting here to the alleged privacy of experience to its possessor. The point of view in question is not one accessible only to a single individual. Rather it is a type. It is often possible to take up a point of view other than one's own, so the comprehension of such facts is not limited to one's own case. There is a sense in which phenomenological facts are perfectly objective: one person can know or say of another what the quality of the other's experience is. They are subjective, however, in the sense that even this objective ascription of experience is possible only for someone sufficiently similar to the object of ascription to be able to adopt his point of view — to understand the ascription in the first person as well as in the third, so to speak. The more different from oneself the other experiencer is, the less success one can expect with this enterprise.

Consciousness is what makes the mind–body problem really intractable.

There will never be [a general and complete theory of right and wrong], in my view, since the role of judgment in resolving conflicts and applying disparate claims and considerations to real life is indispensable. Two dangers can be avoided if this idea of noncomprehensive systematization is kept in mind. One is the danger of romantic defeatism, which abandons rational theory because it inevitably leaves many problems unsolved. The other is the danger of exclusionary overrationalization, which bars as irrelevant or empty all considerations that cannot be brought within the scope of a general system admitting explicitly defensible conclusions. This yields skewed results by counting only measurable or otherwise precisely describable factors, even when others are in fact relevant. The alternative is to recognize that the legitimate grounds of decision are extremely various and understood to different degrees. This has both theoretical and practical implications.
