Bissell offers a new interpretation and clarification of Rand's definition of art, maintaining that an artwork, like language, functions as a "tool of cognition," and that it does so more specifically as a special kind of microcosm which presents an imaginary world. In particular, he argues that architecture and music are aesthetic microcosms and tools of cognition that re-create reality and embody fundamental abstractions and, thus, contrary to assertions by certain Objectivist writers, are forms of art consistent with Rand's definition (...) and concept.
