re: Wrong, and wrong.
If a clone of Mozart was never exposed to music then yes obviously he would exhibit no musical talent. But there is a genetic element. If there wasn't then everyone with the same level of training in music (or anything else for that matter) would have identical levels of skill. This is clearly not the case. Some individuals show much great adeptness and talent than others. Your skinnerian environmental determinism is on the opposite extreme of what you are saying about anyone (not me) who claim genetics would be the sole determinant. It doesn't wash.
Apology accepted and I apologize in turn.
