Instrumental Rationality vs Value Rationality

Weber distinguished four fundamental orientations of social action: traditional, affectual, instrumental-rational (Zweckrationalität), and value-rational (Wertrationalität). Instrumental rationality asks: given that we want X, what is the most efficient means of achieving X? The question presupposes the end has been determined and concerns itself with optimizing means. Value rationality asks whether the end is worth pursuing at all. The distinction is the most important conceptual tool for understanding the moral dimension of the AI transition, and its absence from the dominant discourse is among the most serious analytical failures of the contemporary conversation. AI is an instrument of instrumental rationality of unprecedented power. It optimizes means with thoroughness no previous technology has matched. It is constitutively incapable of answering whether the ends are worth pursuing — and its use systematically displaces value-rational deliberation at the level of individual consciousness.
