Such paradoxes suggest the need for a more extensive theory of the mind than has been so far assumed. We have referred somewhat loosely to the sensory and intellectual components of human experience but have said little about the possible relations and dependencies that exist between them. Perhaps, therefore, the paradoxes result only from our impoverished description of the human mind and are not intrinsic to the subject matter of aesthetic interest.

Many modern philosophers have at this point felt the need to invoke imagination, either as a distinct mental “faculty” (Kant) or as a distinctive mental operation by virtue of which thought and experience may be united. For empiricist philosophers (such as David Hume, Joseph Addison, Archibald Alison, and Lord Kames), imagination involves a kind of “associative” process, whereby experiences evoke ideas, and so become united with them. For Kant and Hegel, imagination is not associative but constitutive—part of the nature of the experience that expresses it.

Once again it is useful to begin from Kant, who distinguished two uses of the imagination: the first in ordinary thought and perception, the second in aesthetic experience. When I look before me and see a book, my experience, according to Kant, embodies a “synthesis.” It contains two elements: the “intuition” presented to the senses and the “concept” (“book”), contributed by the understanding. The two elements are synthesized by an act of the imagination that constitutes them as a single experience—the experience of seeing a book. Here imagination remains bound by the concepts of the understanding, which is to say that how I see the world depends upon my disposition to form determinate beliefs about it—in this case, the belief that there is a book before me. In aesthetic experience, however, imagination is free from concepts and engages in a kind of free play. This free play of the imagination enables me to bring concepts to bear on an experience that is, in itself, free from concepts. Thus there are two separate ways in which the content of experience is provided: one in ordinary perception, the other in aesthetic experience. In both cases the operative factor, in holding thought and sensation together, is the imagination.

Whether such theories can cast light on the mysterious unity between the intellectual and the sensory that we observe in aesthetic experience remains doubtful. The argument for saying that there is a single process of imagination involved in all perception, imagery, and remembering seems to consist only in the premise (undoubtedly true) that in these mental processes thought and experience are often inseparable. But to suppose therefore that there is some one “faculty” involved in forging the connection between them is to fail to take seriously the fact that they are inseparable.

Nevertheless, even if we find this general invocation of imagination, as the “synthesizing force” within perception, vacuous or unilluminating, we may yet feel that the imagination has some special role to play in aesthetic experience and that the reference to imagination has some special value in explaining the precise way in which a content and an experience become “fused” (to use George Santayana’s term). Whether or not Kant was right to refer to a free play of imagination in aesthetic experience, there certainly seems to be a peculiarly creative imagination that human beings may exercise and upon which aesthetic experience calls. It is an exercise of creative imagination to see a face in a picture, since that involves seeing in defiance of judgment—seeing what one knows not to be there. It is not in the same sense an imaginative act to see a face in something that one also judges to be a face. This creative capacity is what Jean-Paul Sartre is referring to in L’Imaginaire: psychologie phénoménologique de l’ima-gination (1940; “The Imaginary: The Phenomenological Psychology of the Imagination”; Eng. trans. The Psychology of Imagination) when he describes imagining as “the positing of an object as a nothingness”—as not being. In memory and perception we take our experience “for real.” In imagination we contribute a content that has no reality beyond our disposition to “see” it, and it is clear that this added content is frequently summoned by art when, for example, we see the face in a picture or hear the emotion in a piece of music.

interior design: Aesthetic components of design

Recent work in aesthetics, to some extent inspired by the seminal writings of Sartre and Wittgenstein, has devoted considerable attention to the study of creative imagination. The hope has been to provide the extra ingredient in aesthetic experience that bridges the gap between the sensory and the intellectual and at the same time shows the relation between aesthetic experience and the experience of everyday life—an enterprise that is in turn of the first importance for any study that seeks to describe the moral significance of beauty.

Consider, for example, the spectators at a performance of William Shakespeare’s King Lear. They see before them an actor who, by speaking certain lines and making certain gestures, earns his bread. But that is not all that they see. They also see a hoary king, cast down by age, pride, and weakness, who rages against the depravity of humankind. Yet the spectators know that, in a crucial sense, there is no such king before them. It is intellectual understanding, not psychical distance, that prevents them from stepping onto the stage to offer their assistance. They know that the scene they enjoy is one that they invent, albeit under the overwhelming compulsion induced by the actor and his lines. The spectators are being shown something that is outside the normal commerce of theoretical and practical understanding, and they are responding to a scene that bears no spatial, temporal, or causal relation to their own experience. Their response is quintessentially aesthetic. For what interest could they have in this scene other than an interest in it for its own sake, for what it is in itself? At the same time, what it is in itself involves what it shows in general. In imaginatively conjuring this scene, the spectators draw upon a wealth of experience, which is brought to mind and, as it were, condensed for them into the imaginative perception of the play. (Hence, Aristotle believed that poetry is more general than history, since its concreteness is not that of real events but rather that of imaginary episodes constructed so as to typify human destiny in exemplary form.)

Such an exercise of the imagination clearly has much to tell us about the nature of aesthetic experience. Whether or not it could found a theory of the “missing link” between sensory enjoyment and intellectual understanding, it at least provides a paradigm of the relation between aesthetic experience and the experience of everyday life. The former is an imaginative reconstruction of the latter, which becomes interesting for its own sake precisely because—however realistic—it is not real.
