I would remind you that extremism in the defense of liberty is no vice! And let me remind you also that moderation in the pursuit of justice is no virtue.

Barry Goldwater delivered this line in his acceptance speech for the Republican presidential nomination at the 1964 Republican National Convention in San Francisco. The phrase responded to criticism—common from moderates and Democrats—that his brand of conservatism and anti-communist foreign policy rhetoric was “extremist.” By turning the charge on its head, Goldwater sought to rally the party’s conservative wing and frame the election as a moral contest over liberty and justice rather than a debate over incremental policy. The remark became one of the defining soundbites of the 1964 campaign and a touchstone for the emerging modern conservative movement.

Goldwater’s formulation is a piece of political antithesis: it reverses the usual moral valuation of “moderation” and “extremism.” He argues that the ethical worth of a stance depends on the cause it serves—liberty and justice—rather than on its intensity. In this framing, “extremism” signifies uncompromising principle, while “moderation” can imply complacency or moral timidity in the face of injustice. The line’s power lies in its absoluteness and cadence, but it also courts controversy by suggesting that restraint is inherently suspect, a stance critics read as license for radicalism. Historically, it crystallized a politics of conviction over consensus.

1) "Extremism in defense of liberty is no vice. Moderation in pursuit of justice is no virtue." 2) "Extremism in the defense of liberty is no vice; moderation in the pursuit of justice is no virtue."
