I recently read an interesting article by John McCarthy that set me thinking. The paper is called The Well Designed Child and talks a bit about about the old nature versus nurture debate: to what extent is a newborn child a blank slate, and to what extent are human intellectual capabilities intrinsic and instinctual?
To me, the whole question of nature versus nurture has always seemed odd. It's clear that both aspects are important. We are all limited to one extent or another in what we can do purely by the physical parameters of our existence: as much as I would like to teleport myself to Europa to frolic in the sunless sea beneath the ice, I can't, and never will be able to. Equally though, the potential that exists in all of us at birth can be squandered, and without education and opportunity, none of us can make of ourselves all that we might. So, we need a bit of both.
