Once we have taken the backward step to an abstract view of our whole system of beliefs, evidence, and justification, and seen that it works only, despite its pretensions, by taking the world largely for granted, we are not in a position to contrast all these appearances with an alternative reality. We cannot shed our ordinary responses, and if we could it would leave us with no means of conceiving a reality of any kind.
Thomas NagelIt is prima facie highly implausible that life as we know it is the result of a sequence of physical accidents together with the mechanism of natural selection. We are supposed to abandon this naรฏve response, not in favor of a fully worked out physical/chemical explanation but in favor of an alternative that is really a schema for explanation, supported by some examples. What is lacking, to my knowledge, is a credible argument that the story has a nonnegligible probability of being true.
Thomas NagelIf you want the truth rather than merely something to say, you will have a good deal less to say.
Thomas NagelA theory of motivation is defective if it renders intelligible behaviour which is not intelligible.
Thomas NagelThe external view [of agency] forces itself on us at the same time that we resist it. One way this occurs is through the gradual erosion of what we do by the subtraction of what happens.
