The Emotivist Catastrophe

Imagine a world where everyone speaks the language of science—using terms like "experiment," "hypothesis," "evidence"—but no one remembers what these words actually meant in their original context. Debates rage on, but they're incoherent because the shared framework is gone. MacIntyre suggests our moral conversations today are in exactly that state.

In After Virtue, Alasdair MacIntyre opens with a "disquieting suggestion": modern moral discourse is fragmented, survivals from a lost tradition without the coherence that once gave it meaning. The Enlightenment rejected Aristotelian teleology (human life directed toward an objective good) and replaced it with competing, incompatible systems: utilitarianism, Kantianism, and others. What remains is emotivism: moral judgments as expressions of personal preference or feeling, with no shared way to resolve disagreements. That is why contemporary moral arguments about justice, rights, or war feel endless and shrill. They lack shared criteria beyond assertion and power. This path moves from the diagnosis of emotivism through practices and internal goods to narrative unity and traditions, and ends with MacIntyre's call for new communities to sustain virtue.

“Imagine that the natural sciences were to suffer the effects of a catastrophe. A series of environmental disasters are blamed by the general public on the activities of scientists. Widespread riots occur, laboratories are burnt down, physicists are killed or forced to flee... In the dark ages which follow, the remnants of the scientific community continue to practise what they call science, but without any understanding of what they are doing... all that they possess are fragments: a knowledge of experiments detached from any knowledge of the theoretical context which gave them significance... Nobody, or almost nobody, realises that what they are doing is not natural science in any proper sense at all.”— Alasdair MacIntyre, After Virtue, Chapter 1, "A Disquieting Suggestion" (University of Notre Dame Press, 2007 ed., pp. 1–2)

MacIntyre's thought experiment is diagnostic, not literal history. He applies the "fragments" image to morality: we retain moral language ("justice," "rights," "good") but lost the teleological context where virtues served a shared human good. Emotivism follows: moral claims become "nothing but expressions of preference" (pp. 11–12). The vivid catastrophe in the excerpt explains why moral arguments today often reduce to clashing wills. No common framework exists to adjudicate them. That explains cultural impasses where opponents talk past each other and treat morality as taste rather than reasoned pursuit of the good.

Consider climate change debates. Activists appeal to "justice" for future generations; opponents cite "economic freedom" or "personal choice." Both use moral terms, but arguments devolve into assertions ("it's wrong!" vs. "it's my right!"). MacIntyre would say this is emotivism in action. No shared telos or tradition anchors "justice," so power decides. A virtue tradition might frame stewardship as a practice with internal goods (sustainable flourishing), shifting debate from preferences to shared human good.

If moral language is fragmented survivals, can we recover coherence without inventing traditions from scratch? Or is emotivism the honest endpoint of modernity?
