Full Idea
Our emotional capabilities are not fully open to be developed. …First, they are to some extent cognitively impenetrable. Secondly, they can ground certain sorts of weakness of will, or akrasia.
Clarification

Gist of Idea
Emotions are not easily changed, as new knowledge makes little difference, and akrasia is possible

A Reaction
Education makes us more receptive to evidence. We could probably rate emotions on a scale indicating how easy they are to change. Jealousy seems tenacious. Most fears respond quickly to clear evidence.
