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.
