"The psychology of a complex mind must differ almost as much from that of a simple, mechanized mind as its psychology would from ours; because something that must underlie and perhaps be even greater than sex is involved"
About this Quote
The line lands hardest at the end, where he smuggles in a taboo comparator: “something… greater than sex.” In early 20th-century intellectual culture, sex was shorthand for the deep engine of behavior - Freud’s gravitational center. Bernal isn’t being salacious; he’s signaling that whatever organizes a truly complex intelligence may be anchored in drives as fundamental as reproduction is to humans, yet not reducible to it. Subtext: stop projecting romance, rivalry, ego, or libido onto minds that may be structured around entirely different imperatives (survival in new substrates, expansion, information hunger, collective coordination).
Contextually, Bernal sits at the intersection of scientific modernism and speculative futurism: a scientist thinking in cosmic time, when “mechanized mind” suggested both industrial automation and the early dream (or dread) of artificial intelligence. The sentence reads like a warning label for anthropomorphism - and a dare to imagine motivation without familiar instincts.
