A Historical Look at Unity  \nThe notion that science is unified in one way or another dates back at least to Aristotle, though unity claims since then have been diverse and variously motivated. By way of introduction to the modern discussion of unity, disunity, and integration, in this first section we examine five historical attempts to unify knowledge: Aristotle’s metaphysical and hierarchical unity; the Enlightenment project of the French Encyclopedists; the systematic unity of Naturphilosophen Lorenz Oken; the methodological unity of the Vienna School’s Encyclopedia of Unified Science; and finally, the organizational unity of cybernetics and general systems theory. We treat these unification projects not only as context, but also because, as we shall see, something of their momentum carries over into the modern discussion.  \n1.1. Aristotle’s Metaphysical and Hierarchical Unity  \nAristotle arranged the ‘sciences’ into three divisions: the theoretical sciences (metaphysics, mathematics, and physics): the practical sciences (e.g., ethics and politics), and the productive sciences (e.g., poetry and rhetoric) . That is, he divided sciences according to their purposes. Theoretical sciences are concerned with knowledge alone and for its own sake, practical sciences  \n1 We thank Adele Abrahamsen, Elihu Gerson, and Theo Kuipers for their very helpful comments and suggestions on earlier drafts ofthis paper.  \nare for doing, and productive sciences are for making. Despite these divisions, however, Aristotle’s image of the sciences was one of a unified hierarchy. In the Metaphysics, he made clear that the theoretical sciences—most particularly metaphysics or ‘theology’—are at the top of the hierarchy. These are the sciences that investigate first causes, and the people who know them know universally and in the highest degree, as well as “understand…all the underlying subjects”(Metaphysics A.2) .  \nAristotle argued that the theoretical sciences are the most basic. It is by virtue of theoretical knowledge that one has true command of practical and productive matters. Without theory, one merely has experience. With theory, one has art (techné) . Consider Aristotle’s example of the physician who treats Callias. Medicine for Aristotle is a practical science, but its practice is enhanced by a grasp of theory. The better physician will not be one who knows only how to treat Callias, or men of a certain age, or those with the specific ailment afflicting Callias. Rather, the better physician will be one who understands disease qua disease, according to its principles and causes, and understands people qua people.  \nThis consequence of a science’s rank in the hierarchy applies even within the theoretical sciences. It is by virtue of doing metaphysics, the highest theoretical science, that one truly grasps the lesser two theoretical sciences. That is, the better physicist or mathematician is one who understands metaphysics. As Aristotle makes clear in the middle books of the Metaphysics, he thinks there are causes and substances that are beyond the reach of physics.
