What is it that creates varying level's of intelligence? What was it about Plato or Aristotle or Nietzsche, or Einstein or any of the genius's that separates their intellectual capacity from mine? I realize it could just be the physical set up of their brains and their simply being born with a physically superior brain than most. However, if this is the case, wouldn't it seem possible that we could physically alter peoples intellectual capabilities, or genetically design them to an advantage. This also makes me believe that, if I my brain is physically deficient, would it be impossible to become any more intellectual (increase my learning capacity) by myself through study? It seems I'm stuck with the brain that I got and I have no hope, so at the end of the day I'm just not going to be able to be that smart. What is it that separates me or you or anyone from genius? Can we earn it? (I recall Nietzsche said most genius's are not born a genius.) Or is it all up to the genetic coin toss? If I could make myself a genius through obsessive application to studies it would seem then that it wasn't necessarily just up to the physical aspect of the brain, but also attainable by some unrelenting will and drive. Is it possible to make yourself a genius?
