It has yet to be proven that intelligence has any survival value.

Clarke’s line is a dry, evolutionary provocation: natural selection rewards traits that increase reproductive success in a given environment, not traits we admire as “higher” or morally superior. By framing intelligence as something whose “survival value” is unproven, he punctures human exceptionalism and questions the assumption that greater intellect necessarily leads to long-term flourishing. In a twentieth-century context—shadowed by nuclear weapons, ecological strain, and technological risk—the remark also reads as a warning that intelligence can amplify self-destructive capacities as easily as it solves problems. The quote’s sting lies in its reversal: intelligence may be impressive, but it is not automatically adaptive.
