"The whole course of human history may depend on a change of heart in one solitary and even humble individual - for it is in the solitary mind and soul of the individual that the battle between good and evil is waged and ultimately won or lost"
About this Quote
The subtext is an argument about agency under pressure. Peck is writing in the late 20th century, when therapeutic language and geopolitical dread coexisted: postwar atrocities, Cold War anxiety, and a growing suspicion that “everyone is just following incentives.” His counter-move is to relocate the decisive battlefield to “the solitary mind and soul,” where nobody can outsource responsibility. Even if the world is built from institutions, institutions are staffed by people making micro-decisions about cruelty, honesty, and courage.
Rhetorically, the sentence telescopes from “the whole course of human history” down to “one solitary… individual,” then pivots back out to “good and evil.” That compression gives it force: it turns moral life into a lever, not a mood. The insistence that the battle is “ultimately won or lost” in private is both bracing and unsettling. It implies that the most consequential revolutions are often invisible: a refusal to dehumanize, a decision to tell the truth, a willingness to be accountable when no audience is watching.
