The Metaphysics of Practice: Writings on Action, Community, and Obligation. Edited by Kyle Ferguson and Jeremy Randel Koons. New York: Oxford University Press, 2023. 745 pp. Cloth, 115. 00 Wilfrid Sellars thought deeply about ethics, practical reasoning, and intentional agency throughout his career and published extensively on these issues, with much additional unpublished material housed in the Archives of Scientific Philosophy at the University of Pittsburgh. In prominent places Sellars indicates that he regards his ethics as the key to his overarching project of reconciling our manifest nature as norm-governed rational beings with his nominalistic scientific naturalism. Yet with a few noteworthy exceptions, Sellars scholars have only very recently begun to seriously grapple with Sellars's practical philosophy. No one has done more to initiate this recent trend than Jeremy Koons, who, together with Kyle Ferguson, collects in this volume virtually all of Sellars's practical philosophical works, including approximately 200 pages of hitherto unpublished material—mostly correspondences with R. M. Hare, Robert Binkley, Hector-Neri Castañeda, Bruce Aune, and David Solomon. Sellars's published practical philosophical writings are grouped thematically into four parts. A fifth part is dedicated to the unpublished writings. The editors also provide a sixty-page introduction, which offers a synopsis of Sellars's overall vision of us as practically rational moral End Page 728 agents, followed by summaries of each of the nineteen essays and the correspondences published in this volume. Sellars thinks of moral ought-judgments as simultaneously motivationally internalistic (with traditional emotivism) and as truth-apt and more or less rational (with traditional cognitivism). His key idea to combine these seemingly incongruent commitments is to regard moral ought-judgments as a species of we-intentions. Since intentions generally are "conceptually tied" to practice, in the sense that (absent interferences or defeaters) they determine proper action in accordance with norms of practical reasoning, we get, in this sense, a version of motivational internalism. Sellars models these normative connections in terms of a nuanced logic of practical reasoning—basically a logic of means–ends reasoning—that is largely parasitic on the logic of theoretical reasoning. This logic is cast in terms of shall-statements, which are linguistic expressions of intentions of the forms "Shall-be p" and "Shall I do A if in C, " where the "Shall-be"s and "Shall"s express the states of intending and the square-bracketed portions the intended contents. Logically proper practical reasoning bottoms out in intentions that immediately give rise to actions (volitions), to be expressed by shall-statements of the form "Shall I do A now. " Sellars makes the case for the truth-aptness of moral ought-judgments by treating them as a species of we-intentions. Such moral we-intentions are expressed by statements of the form "Shall (we) We, any of us, do A if in C, " where both the "we" in the content expression and the "we" indexed to the "shall" are maximally inclusive, comprising every rational being at all. This appears to be what today we would call a combined mode and content account of moral we-intentions, where firs-tperson plural elements are built both into the mode of moral we-intending and the content of moral we-intentions. The truth-aptness of moral we-intentions, Sellars thinks, is secured by the fact that the first-person plural elements of the intention include every rational being at all. Sellars maintains that, due to this maximal inclusion, moral we-intentions are apt to yield genuine interpersonal agreement or disagreement (contra I-intentions) and they ground, via what seems to be a transcendental argument, Sellars's fundamental principle of morality, expressed as "Shall (we) We, any of us, maximize our general welfare). " This principle provides the standard of objective moral correctness for any other moral judgment. Part 1 of the volume includes six essays in which Sellars offers comprehensive articulations of this overall picture, culminating in "Objectivity, Intersubjectivity, and the Moral Point of View" (OIM), the stand-alone seventh chapter of Science and Metaphysics, based on Sellars's 1965–66 John Locke Lectures. . .
