The history of Western philosophy can be presented in a number of ways. It can be told in terms of periods — ancient, medieval and modern. We can divide it into rival traditions (empiricism versus rationalism, analytic versus Continental), or into various core areas (metaphysics, epistemology, ethics). It can also, of course, be viewed through the critical lens of gender or racial exclusion, as a discipline almost entirely fashioned for and by white European men.

Yet despite the richness and variety of these accounts, all of them pass over a momentous turning point: the locating of philosophy within a modern institution (the research university) in the late 19th century. This institutionalization of philosophy made it into a discipline that could be seriously pursued only in an academic setting. This fact represents one of the enduring failures of contemporary philosophy.

Take this simple detail: Before its migration to the university, philosophy had never had a central home. Philosophers could be found anywhere — serving as diplomats, living off pensions, grinding lenses, as well as within a university. Afterward, if they were “serious” thinkers, the expectation was that philosophers would inhabit the research university. Against the inclinations of Socrates, philosophers became experts like other disciplinary specialists. This occurred even as they taught their students the virtues of Socratic wisdom, which highlights the role of the philosopher as the non-expert, the questioner, the gadfly.

Philosophy, then, as the French thinker Bruno Latour would have it, was “purified” — separated from society in the process of modernization. This purification occurred in response to at least two events. The first was the development of the natural sciences, as a field of study clearly distinct from philosophy, circa 1870, and the appearance of the social sciences in the decade thereafter. Before then, scientists were comfortable thinking of themselves as “natural philosophers” — philosophers who studied nature; and the predecessors of social scientists had thought of themselves as “moral philosophers.”
