Agnes Callard at The Point:
If you tell me to calm down, I probably won’t. The same goes for: “be reasonable,” “get over it already,” “you’re overreacting,” “it was just a joke,” “it’s not such a big deal.” When someone minimizes my feelings, my self-protective reflexes kick in. My body, my mind, my job, my interests, my talents—these are all “mine”—but nothing has quite the power to declare itself as “mine” as a passionate emotion does. When waves of anger or love or grief wash over me, that emotion feels like life itself. It wells up from an innermost core, like my voice, which it usually inflects. And so if you move to tamp it down, I parry by shutting you out: I erect walls around my sanctum sanctorum, to shield the flame of my passion—my life—from your soul-quenching intrusions. Who are you to tell me what I can and cannot feel?!
Now imagine a much more ambitious intervention—someone who doesn’t just want to quench some particular bout of anger or grief, but to put an end to anger or grief, simpliciter. Who could possibly have the gall to tell the entire human race what it should and should not feel? Philosophers, that’s who!
