Imagination is the chief instrument of the good. It is more or less a commonplace to say that a person’s ideas and treatment of his fellows are dependent upon his power to put himself imaginatively in their place. But the primacy of the imagination extends far beyond the scope of direct personal relationships. Except where “ideal” is used in conventional deference or as a name for a sentimental reverie, the ideal factors in every moral outlook and human loyalty are imaginative. The historic alliance of religion and art has its roots in this common quality. Hence it is that art is more moral than moralities. For the latter either are, or tend to become, consecrations of the established order. The moral prophets of humanity have always been poets even though they spoke in free verse or by parable. Uniformly, however, their vision of possibilities has soon been converted into a proclamation of facts that already exist and hardened into semi-political institutions. Their imaginative presentation of ideals that should command thought and desire have been treated as rules of policy. Art has been the means of keeping alive the sense of purposes that outrun evidence and of meanings that transcend indurated habit.

-John Dewey, Art as Experience
