Adequate ideas are the fundamental element of Spinoza’s epistemological program. However, a recurrent worry among scholars is that Spinoza’s account of adequate ideas is inconsistent with any finite being ever having one. As I frame it, the problem is that for Spinoza an idea is adequate in a mind only if all its causal antecedents lie within the mind as well. However, it seems there can be no finite mind for which this is true; finite minds come to be and (...) exist within a deterministic causal nexus, and the causal antecedents of every idea in a mind will ultimately stretch far beyond it. I call this the External Cause Objection. I argue that Spinoza appreciated and explicitly answered this concern. According to this reply, adequate ideas do not have causes external to the mind because they do not fall into the category of what Spinoza calls “singular things.” In addition to showing that this coheres with his more specific claims about adequate ideas and his firm belief that finite minds are parts of nature, I argue that the resolution to this problem sheds light on Spinoza’s understanding of what I call absolute agency.

In this essay, I suggest that Spinoza acknowledges a distinction between formal reality that is infinite and timelessly eternal and formal reality that is non-infinite (i. e., finite or indefinite) and non-eternal (i. e., enduring). I also argue that if, in Spinoza’s system, only intelligible causation is genuine causation, then infinite, timelessly eternal formal reality cannot cause non-infinite, non-eternal formal reality. A denial of eternal-durational causation generates a puzzle, however: if no enduring thing – not even the sempiternal, indefinite individual (...) composed of all finite, enduring things – is caused by the infinite, eternal substance, then how can Spinoza consistently hold that the one infinite, eternal substance is the cause of all things and that all things are modes of that substance? At the end of this essay, I sketch how Spinoza could deny eternal-durational causation while still holding that an infinite, eternal God is the cause of all things and that all things are modes. I develop the interpretation more in the companion essay.1 1 In “Spinoza’s Monism II,” in the next issue of this journal. (shrink)

People attribute resistance to bodies in Spinoza's physics. It's not always clear what they mean when they do this, or whether they are entitled to. This article clarifies what it would mean, and examines the evidence for attributing resistance. The verdict: there's some evidence, but not nearly as much as people think.

In this paper, I argue that Spinoza holds a perspectivalist view of mereological composition, a form of anti-realism. The paper has two parts: In the first half of the paper, I introduce interpretive puzzles for the standard realist reading of Spinoza’s mereology. In the second half of the paper, I discuss Spinoza’s positive view on mereological composition and present a perspectivalist reading that avoids the interpretive puzzles.

I argue that we should rethink the nature and scope of Spinoza’s “one and the same” relation. Contrary to the standard reading, the nature of this relation is not identity but a union, and its scope includes all idea-object pairs, even God and the idea of God. A crucial reason we should adopt this dual picture is that the idea of God must be one and the same as something found when Nature is conceived under each of the other attributes. (...) If “one and the same” is interpreted as a relation of identity, this requirement cannot be met. However, maintaining that God and the idea of God are one and the same not only fulfills this requirement, but also is independently motivated. I also briefly consider how the thesis that God and the idea of God are one and the same affords us with positive insights concerning the nature of this relation. (shrink)
