We like to think reason guides our lives, but reason itself is only – as Schopenhauer puts it, echoing Hume – the hard-pressed servant of the will. Our intellects are not impartial observers of the world but active participants in it. They shape a view of it that helps us in our struggles. Among the imaginary constructions created by the intellect working in the service of the will, perhaps the most delusive is the view it gives us of ourselves – as continuing, unified individuals.
