Human Nature

Dubos traces a detail most people skip: the Sumerian word *namlulu* began as a census term — mankind, the headcount — and over centuries became an ethical concept, closer to "humanity" as in decency, compassion, the thing a father accuses his son of neglecting. That semantic drift is the entire nature-nurture debate in miniature, already underway five thousand years before Locke and Hobbes picked sides. Einstein, writing about socialism of all things, lands on the same fault line — humans possess a "biological constitution which we must consider fixed" alongside a "cultural constitution" that is endlessly rewritable — but he treats this as grounds for hope rather than despair. What's striking is that science fiction, which obsessively tests human nature against alien contact and technological rupture, almost never dramatizes this specific tension: not whether humans are good or bad, but whether "human" is a noun or an adjective. The word keeps trying to become a verb.
