The role of the theory of prototypes in moral thought

In this article I attempt to highlight and briefly analyze some problematic aspects of the theory of prototypes and its implications in moral thought. I focus on the issue of moral judgement and the impact of prototypicality on our understanding of moral concepts. The objective of the article is to indicate the significance of the new perspectives opened by the notion of prototype, but also to point out certain difficulties. Some of the problematic questions emerge from the very existence of the prototype structure of categories and concepts; other problems arise with reference to the proposed implications or postulates which are connected with the acknowledgement of the significance of prototypicality. Due to the recognition of the practical dimension of ethics, the main issues are presented through examples of concepts which are commonly used in everyday life, referring to political and social values, traits of character and emotions.
