We rebel against anti-rationalist propaganda: Critical thinking is our best tool, and frees us from culturally induced emotions. We are emotionally intelligent.
The metaphor "think with your heart" has gone too far.
We have made so much use of it that it seems that we have made it become a parallel reality which belief we are close to touch. The heart, symbol of love, is depicted everywhere, not as a simple icon, but as a really conscious, active and independent character. Pulled by this overdeveloped imaginery, by these heart cartoons, we draw conclusions that are consistent with the metaphor, not with the reality that that metaphor seeks to partially represent.
