My son (10) has just asked me if in a certain question in life my heart says one thing, while my mind says another one, which one I would listen to.
After short consideration I replied I would more likely listen to my mind.
I asked back, and he said it depends on the topic: if it is a love issue, he would listen to his heart. If it concerns a mathematical exercise, he would listen to his mind, as 2+2 will not become 128 only because he listened to his heart and 128 is his favourite number.
Logic.
