This paper examines the rabbinic concept of impurity in terms of the essence of the reality that this term implies. Did the Rabbis consider impurity to be a force of nature, or rather an abstract formalistic structure devoid of any actual existence? A review of rabbinic sources regarding corpse impurity reveals that the essential structures of tannaitic halakhah are grounded in a natural, immanent perception of impurity, which gave rise to an entire system, intricate and coherent, of “natural laws of impurity.” Layered onto this system, as a secondary stratum of sorts comprising exceptions and “addenda,” is a more subtle halakhic tapestry woven from a diametrically opposed perception. This view subjects the concept of impurity to human awareness and intention, severing it from reality and, in so doing, also stripping it of its “natural” substance.

Underlying Principle

Physics I 6 addresses the question of the number of principles and motivates the need for an underlying principle in addition to the contrary ones argued for in chapter 5. Physics I 6 ends in aporia about whether there are two or three principles, an aporia which is resolved with Aristotle’s own account in I 7. This chapter focuses on two issues. First, it explores how Aristotle’s arguments for contrary and underlying principles give rise to the aporia. Second, it discusses Aristotle’s puzzling attitude towards, and use of, materialist views in I 6 and, more generally, in book I. Though Aristotle brings out deep tensions between his own hylomorphic conception and materialism, he also seems to downplay them for the purposes of arguing for an underlying principle. I suggest that this is a result of trying to motivate a hylomorphic conception of natural substance from within a more familiar materialist framework.

The Way

AbstractAristotle introduces Physics I as an inquiry into principles; in this paper I ask where he argues for the position he reaches in I 7. Many hold that his definitive argument is found in the first half of I 7 itself; I argue that this view is mistaken: the considerations raised there do not form the basis of any self-standing argument for Aristotle's doctrine of principles, but rather play a subordinate role in a larger argument begun in earnest in I 5. This larger argument stalls in I 6, which ends in aporia; I argue that the problem lies in the fact that Aristotle's reasoning in I 6 thoroughly undermines his reasoning in I 5 (on which I 6 is ostensibly supposed to build). I further argue that the materials necessary for resolving this problem, and thereby allowing the argument begun in I 5 to reach its proper conclusion, are supplied by the thesis that organizes the first half of I 7. Along the way I offer some remarks about Aristotle's doctrine of principles, arguing that it is about the principles of natural substance (as opposed to coming to be or change). I also offer some remarks about the thesis which organizes the first half of I 7. I argue negatively that it is not anything like a preliminary statement of Aristotle's doctrine of principles. I argue positively that it reflects Aristotle's idea that there are two distinct kinds of effect change has upon things (one constructive, the other destructive). One of these effects lies behind Aristotle's reasoning in I 5, the other comes to the fore in I 6; the achievement of the first half of I 7 is to reconcile these seemingly competing conceptions by finding a place for them both in a unified account of coming to be and its subjects.
