> For the past few centuries humanism has seen the human heart as the supreme source of authority not merely in politics but in every other field of activity. From infancy we are bombarded with a barrage of humanist slogans counselling us: “Listen to yourself, be true to yourself, trust yourself, follow your heart, do what feels good.”

I'm just reading a book by Norbert Elias (https://en.wikipedia.org/wiki/Norbert_Elias), who, when writing about his theory of the "civilizing process", stated exactly the contrary. More exactly, he's saying that we only listened to our hearts/true self/passions back when we were "un-civilized", like in the Middle Ages, but after the State monopolized the use of force and the collecting of taxes and after the "société de cour" formed people had to suppress their passions/heart and had to "rationalize" their external actions.
