"Solipsism, incidentally, results if one misinterprets sympathetic imagination as if it worked like perceptual imagination: it then seems impossible to imagine any experience that is not one's own"
He's talking about how we are unable to experience another
person's experience, but we still have the ability to sort-of relate to
another person's experience through comparison, putting ourselves in
their point of view.
we become solipsists if we are unable to be sympathetic to another
person's point-of-view. The
philosophical solipsism purports that we are the only consciousness - so
is Nagel just dismissing that as completely mistaken? Or is he just
avoiding that idea?
