"The only deadly sin I know is cynicism"
About this Quote
The line works because it flips expectations. We usually treat cynicism as sophistication: the knowing smirk, the refusal to be fooled. Stimson calls it lethal, not because it hurts feelings, but because it dissolves the possibility of collective action. A cynical public won’t sacrifice; a cynical bureaucracy won’t take responsibility; a cynical leader can justify anything by claiming everyone else is just as compromised. Cynicism is the solvent that makes hard choices feel weightless.
There’s subtext, too, about the moral posture required to wield power. Stimson isn’t naïve - his career intersects with war planning, secrecy, and the brutal arithmetic of “necessary” measures. Naming cynicism as the sin is a way of defending seriousness itself: you may have to do grim things, but you don’t get to sneer at the very idea of right and wrong. For a governing class tempted by fatalism, it’s a warning: once you stop believing anything can be better, you’ll start accepting anything can be done.
