 Hegel, one of the founders of the deep conception of historical change broadly characteristic of nineteenth-century German scholarship, proceeded to historicize Kant’s innovation, in effect by historicizing Kant’s categories. They are not inborn, permanent, and universal; on the contrary, they are socio-historically acquired or lost and hence differ from one historical epoch to another. People living in different epochs cognize the world differently. It is tempting to read the Kuhn of Structure as further relativizing and localizing Hegel to specific scientific domains and their paradigms. Kuhn’s model provides endogenous, dynamic mechanisms of (inadvertent) scientific innovations that sow the seeds of the paradigm’s eventual destruction in a vaguely Hegelian sort of dialectical process. It thus becomes possible to experience a change in categorical scheme within one’s own lifetime—the victory of the new paradigm being the small-scale scientific counterpart of Hegel watching Napoleon march in victory through the streets of Jena! Thus it is tempting to regard Kuhnian revolutions as Hegelian revolutions writ small.
