Spinoza: Metaphysical Themes (review)

Writing in the mid-seventeenth century, Spinoza tried to provide conceptual foundations for the newly developing "natural philosophy" of his day. His monism, naturalism, and theory of mind are still intriguing today, but they are notoriously difficult to understand. There is little interpretive consensus with regard to even the most basic concepts and claims. In Spinoza: Metaphysical Themes the diversity of interpretive perspective is vividly on display.

All of the eleven essays in this collection are published here for the first time. They cover a broad range of topics and, taken together, they move us forward in our understanding of Spinoza's basic doctrines. Most of the essays are carefully argued discussions of clearly defined issues of interpretation. They address matters that are central to the system and central to our understanding of the system—monism, causation, individuation, conatus.

The editors' Introduction claims that Jonathan Bennett's 1986 work set a new standard of Spinoza scholarship—a standard that the essays in this volume seek to measure up to. Most (not all) of these essays do indeed come close to Bennett's commendable level of argumentative clarity and rigor. And here, as in Bennett's work, the emphasis is mostly systematic and argumentative, not historical.

The collection opens with a very good essay by Michael Della Rocca entitled "Spinoza's Substance Monism." This essay applies to the thorny issue of substance monism the same argumentative strategy that Della Rocca has elsewhere applied to monism regarding individual modes—i.e., to the claim that an extended mode and the idea of that mode are identical. The argument turns on the complete conceptual independence of the attributes, and Della Rocca makes a strong case for the centrality of that somewhat puzzling doctrine. John Carriero's contribution ("Monism in Spinoza") continues the focus on monism, but from a different perspective. Carriero asks, "Why does Spinoza hold that finite . . . bodies are not substances?" (47). Rejecting two traditional responses he provides a plausible answer to this good question by focusing on an early exchange of letters between Spinoza and Oldenburg and upon Spinoza's rethinking of Descartes's conception of extension.

One of the most interesting essays is Don Garrett's interpretive discussion of Spinoza's derivation of the conatus doctrine at Ethics3p4-3p6 ("Spinoza's Conatus Argument"). Commentators have identified various putative fallacies in the argument that Spinoza offers for this doctrine—chiefly fallacies of equivocation. Garrett develops an interesting and plausible notion of "inherence" that casts light on a number of central metaphysical relations and permits a defensible reading of the conatus argument. For the serious Spinoza scholar, this one essay is worth the price of the volume.

Olli Koistinen's "Causation in Spinoza" considers Spinoza's solution to the difficulty of causal interaction between substances—a glaring problem in Descartes that provoked glaringly problematic solutions from Malebranche and Leibniz. Richard Manning's essay addresses a controversial point in Jonathan Bennett's interpretation. The issue is whether, in Spinoza's system, mental content can have causal significance—a point closely related to the important issue of teleological explanation of human behavior. Manning supports a kind of "thoughtful teleology," making a convincing case for the causal efficacy of mental content.

On the whole the authors in this volume restrict their discussion of secondary literature to the works of fellow Anglophones. One finds occasional mention of Gueroult, but the Continental literature on Spinoza is mostly ignored. There are two notable exceptions to this rule. Steven Barbone ("What Counts as an Individual for Spinoza?") discusses the thorny issue of modal individuation in Spinoza's system, arguing against Matheron's 1969 claim that for Spinoza the state is an individual. Emphasizing the centrality of power, Barbone draws important (liberal) political conclusions from his analysis of individuation. Mark Kulstad ("Leibniz, Spinoza and Tschirnhaus: Metaphysics à Trois, 1675-1676") fruitfully uses recent Continental work on...
