General infallibility is a tempting proposition. Treating an individual’s attitudes and preferences as givens – as matters beyond debate or criticism – might seem to promote human dignity by forcing us to treat all views as equally worthy of respect. But such an outlook is likely, if anything, to have the opposite effect. This is because taking seriously a person’s capacity to make mistakes is critical to taking seriously their capacity for rationality. Only by recognising that people are capable of error can we properly value anyone’s goals or engage in rational debate. – Aeon
