The Platonic view that art is incapable of providing us with knowledge is sufficiently widely held as to merit a serious attempt at refutation. Once it is acknowledged that there are alternative forms of knowledge other than propositional, then it is possible to establish the truth of the claim that the knowledge which art affords has a value on a par with that provided by other disciplines. Art, it is argued, has a unique potential to provide imaginative insights by reference to which we may understand what it is like to experience and to feel, in ways very different from those with which we may be familiar. It is shown to be instrumental in enabling us to refine our moral concepts as well as in determining what is salient from the moral point of view. As a powerful tool in the education of the emotions, artworks have the power to increase our moral sensitivity and to sharpen our perception of what is required of us inways that are otherwise unobtainable.
