Abstract
Raymond Boudon is the doyen of French sociology. His 2004 book The Poverty of Relativism counters the relativist plague with philosophical, historical, and comparative deconstruction and proposes an alternative: a cognitive notion of values that rehabilitates the notions of reason, correctness, and progress. More surprising is his rehabilitation of moral evolutionism that restores to it a human face. Will his efforts staunch relativism? Some considerations pro and con are offered. Key Words: relativism reason truth morality social facts.
