Abstract

Michael Strevens develops kairetic account of causal explanations as a brand of explanatory reductionism. He argues that explanations in higher-level sciences are complete (stand-alone) only because they can be potentially deepened—that is, added kernels of causal processes all the way down to the level of micro-physical relations. Thus, they are, in essence, the result of abstraction from deeper causal explanatory levels. I argue that Strevens’s discussion of the notion of depth in science is limited to a very narrow domain, the boundaries of which are determined by a simplistic amalgam of science textbook and everyday cases analyzed by means of rational metaphysics. In contrast to his view, history of scientific practice shows that scientific explanations are typically bounded within a level and do not draw their viability from their potential for lower-level explanatory deepening. Moreover, a result of such deepening of higher-level explanations produces changes and refinements much more complex than Strevens’s account assumes.
