I am not surprised that Seth Schoen is asking us to rethink rationality. And he has done so, beautifully:
Second, and more importantly, this mythical version of rationality denies that anyone has an inner life that matters or that is worthy of respect. It suggests that the inner life, and especially emotions, should always be subordinated to external goals, to decisions related purely to physical survival value. So in this account, whether something will kill you is a valid rational consideration, but whether you are afraid of it is not a valid rational consideration.
