[W]hen the objective gaze is turned on human beings and other experiencing creatures, who are undeniably parts of the world, it can reveal only what … - Thomas Nagel

Ethics increases the range of what it is about ourselves that we can will—extending it from our actions to the motives and character traits and dispositions from which they arise. We want to be able to will the sources of our actions down to the very bottom.

Human beings are subject to moral and other motivational claims of very different kinds. This is because they are complex creatures who can view the world from many perspectives — individual, relational, impersonal, ideal, etc. — and each perspective presents a different set of claims. Conflict can exist within one of these sets, and it may be hard to resolve. But when conflict occurs between them, the problem is still more difficult. Conflicts between personal and impersonal claims are ubiquitous. They cannot, in my view, be resolved by subsuming either of the points of view under the other, or both under a third. Nor can we simply abandon any of them. There is no reason why we should. The capacity to view the world simultaneously from the point of view of one's relations to others, from the point of view of one's life extended through time, from the point of view of everyone at once, and finally from the detached viewpoint often described as the view sub specie aeternitatis is one of the marks of humanity. This complex capacity is an obstacle to simplification.

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.
