The Rebel:
The heart has no emotional feelings like love, it's simply a muscle for pumping blood. Using it in a figure of speech is fine but not for realistic thinking. Like "His heart is in the right place" as a figure of speech is fine, but realistically where else would it be? In his elbow? Good powers of perception have no place for basing decisions on feelings, it's the very reason people in high risk and dangerous professions are taught to control their instincts - instincts all too often influence poor decision making and cost lives.
Evaluation should be pragmatic, not emotional. Compassion is an emotion which motivates us to make us evaluate events which bother our conscience, but evaluting the events themselves should not incorporate emotions, they will only serve to cloud the facts and lead to irrational decisions.
