 Dewey never puts forth an explicit definition of aesthetic experience in terms of necessary and sufficient conditions. However, certain features recur in his numerous discussions. Most importantly, aesthetic experience has a temporal structure. Aesthetic experience is something that develops and attains specific qualities as the experience proceeds. It is in this sense “dynamic because it takes time to complete” (AE: 62). To qualify as an aesthetic experience, there must, moreover, be accumulation between the different phases of the experience: aesthetic experience includes a sense that the later phases build on earlier ones and carry them further rather than just mechanically following them. Aesthetic experiences are also intensive; they condense, for example, emotional and formal features to a single experience. Another key quality of aesthetic experience is a feeling of resistance. These resistances are not obstacles: they feed the experience’s development and accumulation and are converted into movement toward a close. In aesthetic experience, the experiencer is also overcome by a sense of rhythm. Aesthetic experience has an internal momentum and, already from the initial phases, the experiencer can feel a sense of direction in it. In other words, in an aesthetic experience “every successive part flows freely, without seam and without unfilled blanks, into what ensues”. Moreover, “as one part leads to another and as one part carries on what went before, each gains distinctness in itself” (AE: 43). Aesthetic experience also does not terminate at some random point. Rather, its close is a summation of its earlier phases, either in the sense that the energy that has gathered up during the experience is released or the experience reaches a fulfillment in some other sense. In short, aesthetic experience involves “inception, development, and fulfillment” (AE: 62).
