fundamentally an organism has conscious mental states if and only if there is something that it is like to be that organism--something it is like for the organism.
Thomas NagelThe point is... to live one's life in the full complexity of what one is, which is something much darker, more contradictory, more of a maelstrom of impulses and passions, of cruelty, ecstacy, and madness, than is apparent to the civilized being who glides on the surface and fits smoothly into the world.
Thomas NagelIt isn't just that I don't believe in God, and naturally, hope there is no God. I don't want there to be a God; I don't want the universe to be like that.
Thomas NagelIf sub specie aeternitatis [from eternity's point of view] there is no reason to believe that anything matters, then that does not matter either, and we can approach our absurd lives with irony instead of heroism or despair.
Thomas NagelIf a psychological Maxwell devises a general theory of mind, he may make it possible for a psychological Einstein to follow with a theory that the mental and the physical are really the same. But this could happen only at the end of a process which began with the recognition that the mental is something completely different from the physical world as we have come to know it through a certain highly successful form of detached objective understanding. Only if the uniqueness of the mental is recognized will concepts and theories be devised especially for the purpose of understanding it.
