Anger, resentment, antagonism, and strife are the drivers of social progress. Yes, human beings are social, and perhaps even capable of being eusocial, but it is the presocial element of humanity that forces the movement from barbarism to culture. Competition for material and reproductive resources is cutthroat. Threats from the best bring out one's best. Homo homini lupus! Not only between individuals, but between governments. Cooperation and conciliation arise out of shared need and vulnerability; you know, Schopenhauer's porcupines, unsocial sociability, and all that jazz from Vico, Turgot, and Adam Smith. Indeed, as the great Immanuel Kant put it, "human beings desire concord, but nature, she knows better, she wills discord."
Progress, thy name is Trump!
