Pleasantness. Unpleasantness. Arousal. Calm. That's all our brains understand. Any other emotion is our own interpretation based on social constructs. So what is this "loneliness"? What is this "empathy"? What is this "yearning"? What is this "love"? Just feelings on the spectrum of: pleasant, unpleasant, arousal and calm. At first this seems ridiculous. Then it seems hopeful because if all these hard emotions are just constructed, then I don't have to be a slave to them. I can be free. Free to be myself, not ruled by emotional states other than: pleasantness, unpleasantness, arousal and calm.
