Reason-Emotion dichotomy:

The false view that reason and emotions are unrelated and often opposing.

Actually, emotions are a byproduct of one's reasoning and conclusions. The connection is not direct, as the emotions are the product of a subconscious mechanism that is programmed by a persons value-judgments and conclusions. Because it is indirectly controlled, and an automatic mechanism, the results can conflict with a person's rational judgment.

These conflicts are not necessary, though. If one goes through the process of explicitly identifying their values, and judging their past conclusions, they can reprogram their emotional responses to be consist with their own understanding. Conflicts may still arise, but they will become more rare and easier to resolve. The result is a harmonious cooperation of reason and emotion, with the two mirroring each other. There's no necessary conflict between them precisely because emotions are the indirect byproduct of reasoning.
