Moral Progress Through Conceptual Improvements: A Typology and Its Philosophical Lessons

ABSTRACT Conceptual improvements are a significant dimension through which local moral progress occurs, both at the individual and societal levels. Michele Moody-Adams (1999) offers a narrow view of moral progress, suggesting that only a deepened understanding of complex, existing moral concepts can constitute moral progress. Consequently, she views the role of moral philosophy as limited to constructing deeper accounts of these concepts. We broaden Moody-Adams’s (1999) account by identifying three distinct types of conceptual improvements that can constitute moral progress: deepening the understanding of existing concepts, creating new concepts, and enhancing the ability to apply concepts. We support this typology with historical examples where such improvements constituted moral progress. Based on this typology, we argue that the role of moral philosophy extends beyond developing and refining moral theories to include the active creation of new concepts and the facilitation of conceptual application.
