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 NagelThere is a tendency to seek an objective account of everything before admitting its reality.
Thomas NagelIf we tried to rely entirely on reason, and pressed it hard, our lives and beliefs would collapse - a form of madness that may actually occur if the inertial force of taking the world and life for granted is somehow lost. If we lose our grip on that, reason will not give it back to us.
Thomas NagelEveryone is entitled to commit murder in the imagination once in a while, not to mention lesser infractions.
Thomas NagelTo look for a single general theory of how to decide the right thing to do is like looking for a single theory of how to decide what to believe.
Thomas NagelEverything, living or not, is constituted from elements having a nature that is both physical and nonphysical - that is, capable of combining into mental wholes. So this reductive account can also be described as a form of panpsychism: all the elements of the physical world are also mental.
