Isaiah Berlin

Abstract

John Gray’s interpretation of Isaiah Berlin’s value pluralism erroneously conflates incommensurability with incomparability. Although incommensurable values or artistic works lack a precise common scale for measurement, they remain subject to qualitative comparison. The absence of a mathematical metric allows for “imprecise equality,” where distinct entities may be recognized as belonging to the same evaluative league without being strictly superior, inferior, or exactly equal to one another. Gray’s claim that incommensurability precludes progress or decline across traditions suggests that no objective truths exist regarding relative merit between different cultures or eras. However, this view is distinct from Berlin’s actual thesis. Incommensurability does not entail that all works or moral states are beyond comparison; it is possible to maintain that figures from divergent traditions occupy the same high level of achievement while remaining demonstrably superior to lesser counterparts. Consequently, value pluralism does not undermine the framework of a rational morality, as it preserves the capacity for meaningful, albeit imprecise, comparative judgments across diverse ethical and aesthetic systems. – AI-generated abstract.
