The institutions that collectively sponsor and promote research, generally in connection with programs, centers, and departments that administer undergraduate and graduate education; sometimes the professional organizations with which these activities are affiliated; less often, the private and semi-private corporations that contribute to this work. Used pejoratively (i.e., “academic”), the work of said institutions and their denizens insofar as it is difficult or obscure. The term comes by the latter associations honestly, deriving as it does from the grove outside Athens in which Plato delivered lectures. Plato’s Academy was not a school, nor did it have a curriculum. The space was used for exercise in DIALECTIC. By its very nature, this pseudo-method of interrogation and exchange resists the definite conclusions that are required of ordinary tasks, and it inclines toward the speculative limits of philosophical inquiry. When the term returned to prominence in Renaissance Florence after a prolonged period of disuse, it described the flurry of activity being undertaken to recover the learning (or non-learning, as it were) of Ancient Greece. Academia expanded beyond humanistic scholarship in subsequent centuries—in that numerous elite cliques called themselves “academies” in order to describe their shared conception of intellectual endeavor in fields like vernacular writing (Accademia Fiorentina), artistic practice (Akademie der Künste), and scientific research (Académie des Sciences)—but the academies of the seventeenth and eighteenth centuries maintained the esoteric tradition they inherited from Florence and Athens. Alongside their productive research in mathematics, physics, and chemistry, academies sponsored work on magic, alchemy, astrology, and kabbalah. Interest in the hidden or the occult spanned the British, French, and Prussian Academies; practitioners in these domains included Isaac Newton and Gottfried Leibniz. All but the most fervent rationalists presumed that any understanding of the natural world would necessitate a détente with forces that no less sober a mind than David Hume called “obscure and uncertain.” Academies were functionally absorbed by the modern research UNIVERSITY in the nineteenth century, and today academia is effectively indistinguishable from the university itself, in its full socio-cultural and pragmatic reach. The remaining independent academies are in fact populated by scholars essentially all of whom hold university posts. Thus the function of academia in its current form (if not always its explicitly stated mission) is that of the university in its modern configuration: service to the global economy through the production of monetizable knowledge, together with the rearing of students into desirable employees for profitable firms. The tensions with the original design of the “academy” are pronounced, though it is unclear to what extent this genealogical awkwardness imperils the enterprise. If critics no longer accuse academia of concealing a trove of hidden knowledge, they instead levy a charge that is all the more distressing for its banality: that academia is not mysterious, but useless.
