Full Idea
To view 'spirit', the product of the brain, as supernatural. Even to deify it. What madness!
Gist of Idea
It is just madness to think that the mind is supernatural (or even divine!)

When I started philolosophy I was obliged to take mind-body dualism very seriously, but I have finally managed to drag myself to the shores of this lake of madness, where Nietzsche awaited with a helping hand.
