The second event was the placing of philosophy as one more discipline alongside these sciences within the modern research university. A result was that philosophy, previously the queen of the disciplines, was displaced, as the natural and social sciences divided the world between them.

This is not to claim that philosophy had reigned unchallenged before the 19th century. The role of philosophy had shifted across the centuries and in different countries. But philosophy in the sense of a concern about who we are and how we should live had formed the core of the university since the church schools of the 11th century. Before the development of a scientific research culture, conflicts among philosophy, medicine, theology and law consisted of internecine battles rather than clashes across yawning cultural divides.

Indeed, these older fields were widely believed to hang together in a grand unity of knowledge — a unity directed toward the goal of the good life. But this unity shattered under the weight of increasing specialization by the turn of the 20th century.

Early 20th-century philosophers thus faced an existential quandary: With the natural and social sciences mapping out the entirety of both theoretical as well as institutional space, what role was there for philosophy?

A number of possibilities were available: Philosophers could serve as 1) synthesizers of academic knowledge production; 2) formalists who provided the logical undergirding for research across the academy; 3) translators who brought the insights of the academy to the world at large; 4) disciplinary specialists who focused on distinctively philosophical problems in ethics, epistemology, aesthetics and the like; or 5) as some combination of some or all of these.
