Full Idea
The evil Hegel finds at the heart of the good will is not simply the criminal violation of rights, but the evil which lies in believing oneself to be doing what is truly good, while allowing no one but oneself to determine what the good actually is.
Gist of Idea
Evil enters a good will when we believe we are doing right, but allow no criticism of our choice

A Reaction
That is not intellectualism, but the implication that intellectualism is a potential source of evil. The interesting thought is that Hegel is contributing a social dimension to the weakness of will problem.
