Each evening, after the children were in bed, she would teach Paul everything she had learned that day, and they would talk about what it meant for philosophy. Its moral is not very useful for day-to-day work, in philosophy or anything elsewhat are you supposed to do with it?but it has retained a hold on Pauls imagination: he always remembers that, however certain he may be about something, however airtight an argument appears or however fundamental an intuition, there is always a chance that both are completely wrong, and that reality lies in some other place that he hasnt looked because he doesnt know its there. Turns out that burning wood is actually oxidation; what happens on the sun has nothing to do with that, its nuclear fusion; lightning is thermal emission; fireflies are biophosphorescence; northern lights are spectral emission.). Presumably, it will be possible, someday, for two separate brains to be linked artificially in a similar way and to exchange thoughts infinitely faster and more clearly than they can now through the muddled, custom-clotted, serially processed medium of speech. Better to wait until the world had changed, he thought. So what proportion of our political attitudes can be chalked up to genetics? Aristotle knew that. Paul Churchland.

Scientists found that in the brains reward system, the density of receptors for oxytocin in the prairie voles was much higher than in montane voles. This shouldnt be surprising, Nagel pointed out: to be a realist is to believe that there is no special, magical relationship between the world and the human mind, and that there are therefore likely to be many things about the world that humans are not capable of grasping, just as there are many things about the world that are beyond the comprehension of goats. Neuroscientists asked: Whats the difference in their brains?

The Churchlands suggest that if folk-psychological entities cannot be smoothly reduced to neuroscientific entities, we have proven that folk psychology is false and that its entities do not exist. If, someday, two brains could be joined, what would be the result? Use the following words (disengage, regain, emit). Some philosophers think that we will never solve this problemthat our two thousand years of trying and failing indicate that its likely we are no more capable of doing so than a goat can do algebra.
