You’re completely deluded into believing that genius is overrated. While it is never in isolation, and its fruits are the product of historical necessity, it takes a rare breed of sacrifice, which PG here is saying as obsession, to hit the targets no one else sees (paraphrasing Arthur Schopenhauer); and is constitutionally the personal, moral input of an individual on choosing how to cause themselves to be, unconcerned with the mediocre concerns of their contemporary society.

Shame on you and your ilk for suggesting Descartes, Newton, Kant etc. were just there picking low hanging fruit. They were doing work no one had the courage to do.
