The assumption that error theorists claim is at the heart of morality is that all moral claims are false because there is no moralknowledge, for knowledge requires truth and there is no moral truth.
This assumption of error theorists is crucial to an understanding of morality as it precludes moral judgments about what other people and cultures regard as morally acceptable.
Therefore, for error theorists, moral judgments are flawed because they do not aim at the truth, because they are notaccurate in any moral statement.
