If 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.
Thomas NagelHumans are addicted to the hope for a final reckoning, but intellectual humility requires that we resist the temptation to assume that tools of the kind we now have are in principle sufficient to understand the universe as a whole.
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 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.
