"Aesthetics" is often taken to be the study of art, but it has come to mean a variety of rather different things in contemporary educational theory and practice, such as: (i) sensory education; (ii) appreciation of beauty; (iii) education in appreciation of the arts. The danger of running these different senses together is explored and the main argument of this chapter is that the moral significance of the aesthetic dimension of works of art lies in its direct engagement with the affective or emotional aspects of moral development.
