“... Natural science is not occult but accessible to any normal mind, and it generates real, not imaginary power—which confronts us as an alien force, which may even destroy us all. Nuclear bombs are the appropriate symbol, not only in their literal capacity to destroy us all, but also in the universal irresponsibility that they embody. Scientific inventors created them as an unrestricted gift to military and political leaders, who keep insisting in advance that “the adversary” will be responsible if “we” are “obliged” to initiate some “nuclear exchange.””
