This is a quote from one of the greatest movie "Metropolis" (1927) by Fritz Lang. The quote translates into: "The mediator between head and hands must be the heart!" I'm not gonna retell the plot of the movie, because I'd like you to watch it (so no spoilers more). Whichever you've watched it or not, I shall continue.
What do you think about any mediators between minds and the world? Usually they say it is the language or the symbolic world. But I want you to think about some love and feelings. What about them? Should we care about to put them - love and feelings - at the center of all of our actions? Do we need to recheck our science from the rails of mind and hand to the rails of the heart?
Friendliness, care, attentiveness, loyalty, rapport, kindness, sympathy, gentleness, benignity, humaneness, tenderness, solicitude, chariness, gratitude, honesty, fairness, straightforwardness, dependability, cooperativeness, courage, caring, maturity, and love. And many many synonyms to them. All of them are what we need to, at least, to use them daily in our actions to prove that we have them - those qualities - at the center of all of our relations.
And my idea is in that If each of the process what we usually do had necessary contained some of those qualities, then would live happily. So, our happiness isn't about the conditions, it is about the processes between any frames between condition states.
