"At a time when science plays such a powerful role in the life of society, when the destiny of the whole of mankind may hinge on the results of scientific research, it is incumbent on all scientists to be fully conscious of that role, and conduct themselves accordingly"
About this Quote
The phrase “incumbent on all scientists” matters because it rejects the narrow defense that responsibility stops at publication. Rotblat is insisting on professional ethics as civic duty, not optional personal virtue. “Fully conscious” is another tell: he’s diagnosing a cultivated sleepwalking, a culture where specialization can become a kind of moral sedation. The subtext is that the most dangerous scientific error isn’t an incorrect equation; it’s a refusal to ask who benefits, who is harmed, and what institutions are steering the work.
Context sharpens the edge. Rotblat helped work on the Manhattan Project, then left when it became clear Germany wouldn’t build the bomb. He spent the rest of his life arguing that scientists had to own the downstream effects of their breakthroughs, co-founding the Pugwash Conferences and later receiving the Nobel Peace Prize. Read through that biography, “conduct themselves accordingly” is deliberately spare: it avoids prescribing ideology while still demanding a posture - skepticism toward militarization, vigilance about misuse, and a willingness to dissent even when the funding, prestige, and national mood push the other way.
