This chapter takes a fresh look at 3d2 of Spinoza’s Ethics, an absolutely pivotal definition for the ethical theory that ensues. According to it, “we act when something happens, in us or outside us, of which we are the adequate cause,” whereas we are passive “when something happens in us, or something follows from our nature, of which we are only a partial cause.” The definition of activity has puzzled scholars: how can we be an adequate, i.e. complete, cause of (...) an effect outside us (which clearly involves other causal factors as well)? However, the definition of passivity is hardly unproblematic either: how can something follow from the patient’s nature so that the patient can nevertheless be considered only a partial cause? I begin by outlining 3d2 and situating it in the historical context formed by Descartes, Hobbes, and the Aristotelian tradition. Then I show that the existing interpretations do not solve the problem of activity and argue that unraveling the problem requires taking properly into account the distinction between immanent and transeunt causality. In relation to the definition of passivity, I argue that Spinoza’s geometry-inspired theory of essence constitution offers the key to understanding the nature of passions. (shrink)

While both intuitive knowledge and reason are adequate ways of knowing for Spinoza, they are not equal. Intuitive knowledge, which Spinoza describes as the ‘greatest virtue of mind’, is superior to reason. The nature of this superiority has been the subject of some controversy due to Spinoza's notoriously parsimonious treatment of the distinction between reason and intuitive knowledge in the Ethics. In this paper, I argue that intuitive knowledge differs from reason not only in terms of its method of cognition—but (...) also in terms of its content. More specifically, I maintain that there is something that is known by intuition, namely the unique essences of things, that is not known by reason. My argument is supported by an examination of Spinoza's account of essences in the Ethics, which reveals that he is committed to both unique and shared essences. Based on this dual commitment, I argue that whereas for Spinoza both reason and intuition can be said to reach adequate knowledge of the shared essence of a thing, the unique essence of a singular thing, which is nothing but its actual essence, can only be known through intuitive knowledge.

Most discussions of Spinoza and consciousness—and there are not many— conclude either that he does not have an account of consciousness, or that he does have one but that it is at best confused, at worst hopeless. I argue, in fact, that people have been looking in the wrong place for Spinoza's account of consciousness, namely, at his doctrine of "ideas of ideas". Indeed, Spinoza offers the possibility of a fairly sophisticated, naturalistic account of consciousness, one that grounds it in (...) the nature and capacities of the body. Consciousness for Spinoza, I suggest, is a certain complexity in thinking that is the correlate of the complexity of a body, and human consciousness, for Spinoza, is nothing but the correlate in Thought of the extraordinarily high complexity of the human body in Extension. In this respect, Spinoza anticipates the conception of mind that is presently emerging from studies in the so-called ‘embodied mind’ research program. Moreover, this research program, in turn, may hold out hope for a clearer understanding of some of Spinoza's more difficult claims. CiteULike Connotea Del.icio.us What's this? (shrink)

My project in this paper is to fill a gap in Spinoza's theory of metaphysical individuation. In a few brief passages of the Ethics, Spinoza manages to explain his views on the nature of composition and the part-whole relation, the metaphysical facts which ground the individuation of simple bodies and the extended individuals they compose, and the persistence of one and the same individual through time and mereological change. Yet Spinoza nowhere presents a corresponding account of the individuation of simple (...) ideas, or the minds such ideas compose. While it is initially tempting to locate the details of such an account in Spinoza's views on the relation between the mental and physical domains, I argue here that such approaches fail, in conflicting with Spinoza's insistence that the mental and the physical are conceptually and explanatorily independent. By contrast, I show that for Spinoza, each idea essentially possesses the property of affirming the existence of its object, and that such properties are well-suited to serve as the principle of ideal individuation Spinoza never explicitly provided.

Scholars have begun to explore Baruch Spinozas critique of rationalism, largely because of his importance for later thinkers deeply concerned about the nature of body, including Nietzsche, Freud, Marx, Frankfurt school critical theorists, and feminists. Until now, however, Spinozas epistemological writings have not been properly addressed in this revival of interest in his materialism. My dissertation reconstructs Spinozas materialist method of knowing in an effort to reclaim it from Cartesian and idealist readings, offering instead a materialist reading of Spinozas epistemological (...) writings that shows him as the first serious critic of modern rationalism. Contrary to the predominant reading of Spinoza in Anglo-American philosophy, which presents him as a metaphysician dependent on Cartesian epistemology, I argue that Spinoza offers something separate, akin to an epistemology, that distinguishes him from the Cartesian model and allows him to critique it. The dissertation explores how Spinozas method of knowing must involve material conditions, including concrete history, psychology, society, and politics, that are experienced through the body and that render a purely mental criterion for knowledge impossible.

Adequate and inadequate ideas play a central role in Spinoza’s system. A number of recent commentators have suggested that the internality or externality of an idea’s immediate cause is a necessary and sufficient condition of the idea’s adequacy or inadequacy, respectively. I show that this thesis is subject to counterexample and briefly explore the significance of this critique for recent interpretations. I offer an alternative interpretation on which adequate and inadequate ideas are characterized by the manner in which they grasp (...) their objects. Adequate ideas conceive of their objects as following from God. Inadequate ideas conceive of their objects as affecting the body at a time and place. (shrink)
