 The first disjunct is the more important one; it says that something’s a work if it’s an artifact, “an arrangement of conditions”, that was intended by its creator to be capable of providing an experience with non-negligible aesthetic character. It’s important to realize what’s not being said here. First, the definition doesn’t say that a work of art is intended to provide (or be capable of providing) a full-blown aesthetic experience. Only “an experience with marked aesthetic character” is required. Second, the definition doesn’t say that a work of art doesn’t or can’t have a utilitarian function, in the everyday sense of the term. A work of art could be a chair that’s many times simply sat in, for example. Third, the definition doesn’t say that the primary intention behind the creation of the artifact is an aesthetic one. The primary intention behind the creation of a religious icon, for example, could be to bring worshipers closer to God. What makes such an icon a work of art, however, is not that intention but another one: the intention that it be capable of affording viewers an experience with marked aesthetic character. How marked this character must be isn’t specified, but that may be all to the good. As the exact extension of “work of art” is somewhat indefinite, so is the extension of “artifact created with the intention of being capable of affording an experience with marked aesthetic character”. If the extensions of the two are the same or very nearly so, and the objects in the “gray areas”, the areas not definitely within or without the extension of the two, are also the same or very nearly so, then so much the better for the definition.
