I would agree that certain human are born with specific talents that are not taught. The Michaels Jordan's of the world were likely born with abilities. You can't teach everyone to play at that level.
But that's a far cry different to me than saying "basic human goodness can't be taught". Any sort of human goodness would be based on behaviors. Behaviors can be modified, except in some extreme cases.
Ps...sorry trach I see that you didn't use the word goodness, that was the brain.
