Metaethics and Moral Relativism

Metaethics and Moral Relativism moves the conversation from 'What is right?' to 'What does "right" even mean?' This topic investigates the nature of moral language and whether objective moral truths exist. Students debate Moral Relativism (morality is just a cultural preference) versus Moral Objectivism (some things are wrong regardless of culture). This is a critical part of the Ethics strand (D3) as it challenges students to think about the 'status' of their own values.

Formal Debate: The Relativism Paradox

Students debate the statement: 'If moral relativism is true, then we cannot criticize the practices of any other culture, including slavery or genocide.' Groups must use logical consistency to defend or attack the relativist position.

Think-Pair-Share: Is Tolerance Objective?

Pairs discuss: 'Is the idea that we should be tolerant of other cultures a fact that is true for everyone, or just a Western preference?' They share how this question creates a 'trap' for the relativist, then present their findings to the class.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • Relativism is the same thing as being 'nice' or 'tolerant.'

    Relativism is a philosophical claim about the *nature of truth*, not a personality trait. Active learning tasks that show how relativism can actually lead to 'might makes right' help students see the darker logical implications of the theory.

  • If people disagree about morality, there must be no objective truth.

    People disagree about the shape of the earth, but that doesn't mean there isn't a 'true' shape. Peer discussion about the difference between 'disagreement' and 'truth' helps students see that moral disagreement doesn't automatically prove relativism.
