Ethics of Science vs. Human Nature

Weizenbaum identified something most philosophy of science misses: the physical sensation of ethical confrontation. When you introduce the word "ought" into a room of scientists, the temperature drops — and he compares it explicitly to the chill when elderly German academics are reminded of colleagues who thrived under Hitler. The parallel is precise and damning. In both cases the discomfort isn't about abstract principles but about *personal* renunciation — what you yourself failed to refuse. The standard framing pits ethics against human nature, as though our moral sense is a leash on our animal selves. But the tension Weizenbaum actually describes runs the other direction: ethics *is* human nature asserting itself, and the resistance to ethics is the learned behavior — the professional norm, the institutional reflex, the convenient fiction that inquiry has no direction and therefore no driver. Dubos saw the same inversion from biology's side: scientists shy away from studying human life not because it's unscientific but because it won't yield "rapid professional advancement." The selfish calculation masquerades as methodological rigor. What we call human nature — the supposedly amoral animal underneath — turns out to be the professional costume, and the flinch of conscience turns out to be the deeper biology.
