Without consciousness the mind-body problem would be much less interesting. With consciousness it seems hopeless. - Thomas Nagel

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

I believe that there is a necessary connection in both directions between the physical and the mental, but that it cannot be discovered a priori. Opinion is strongly divided on the credibility of some kind of functionalist reductionism, and I won't go through my reasons for being on the antireductionist side of that debate. Despite significant attempts by a number of philosophers to describe the functional manifestations of conscious mental states, I continue to believe that no purely functionalist characterization of a system entails — simply in virtue of our mental concepts — that the system is conscious.

I believe that the general form of moral reasoning is to put yourself in other people's shoes. This leads to an impersonal concern for them corresponding to the impersonal concern for yourself that is needed to avoid a radical incongruity between your attitudes from the personal and impersonal standpoints, i.e. from inside and outside your life. Some considerable disparity remains, because your personal concern remains in relation to yourself and your life: they are not to be replaced or absorbed by the impersonal ones that correspond to them. (One is also typically concerned in a personal way for the interests of certain others to whom one is close.) But we derive moral reasons by forming in addition a parallel impersonal concern corresponding to the interests of all other individuals. It will be as strong or as weak, as comprehensive or as restricted, as the impersonal concern we are constrained by the pressures of congruency to feel about ourselves. In a sense, the requirement is that you love your neighbor as yourself; but only as much as you love yourself when you look at yourself from outside, with fair detachment.

It is often remarked that nothing we do now will matter in a million years. But if that is true, then by the same token, nothing that will be the case in a million years matters now.
