Silence is argument carried out by other means.

The line suggests that refusing to speak can function rhetorically: silence may signal dissent, contempt, strategic restraint, or an inability to answer—each of which can influence an argument as powerfully as words. Read this way, “other means” frames silence as a tactic within conflict and persuasion, akin to nonverbal pressure or political maneuver. However, despite frequent online attribution to Che Guevara, the saying’s phrasing and circulation look more like a later aphorism than a documented remark from his speeches, letters, or published writings. Without a verifiable primary source, any interpretation should be treated as analysis of a modern maxim rather than a securely contextualized Guevara quotation.
