The tenth proposition of Spinoza’s Ethics reads: ‘Each attribute of substance must be conceived through itself.’ Developing and defending the argument for this single proposition, it turns out, is vital to Spinoza’s philosophical project. Indeed, it’s virtually impossible to overstate its importance. Spinoza and his interpreters have used EIp10 to prove central claims in his metaphysics and philosophy of mind (i.e., substance monism, mind-body parallelism, mind-body identity, and finite subject individuation). It’s crucial for making sense of his epistemology (i.e., Spinoza’s (...) account of knowledge and response to skepticism) and in resolving puzzles within the Ethics (i.e., explaining human ignorance of all but two attributes). Even those who do not attribute some of the above claims to Spinoza need EIp10 to defend much of what they believe about Spinoza’s system. This paper locates a previously unnoticed argument for this proposition in Spinoza’s Short Treatise on God, Man, and His Well Being. There, Spinoza shows himself concerned with a powerful and underappreciated form of philosophical skepticism, one with surprising echoes in the work of his contemporary Leibniz as well as in the later Wittgenstein. Spinoza’s introduction of E1p10 in the Ethics circumvents this form of skepticism, solving the problem the Short Treatise envisions while also explaining that text’s argument’s absence from the explicit justificatory structure of the Ethics.

We argue that prevailing definitions of Berkeley’s idealism fail to rule out a nearby Spinozist rival view that we call ‘mind-body identity panpsychism.’ Since Berkeley certainly does not agree with Spinoza on this issue, we call for more care in defining Berkeley’s view. After we propose our own definition of Berkeley’s idealism, we survey two Berkeleyan strategies to block the mind-body identity panpsychist and establish his idealism. We argue that Berkeley should follow Leibniz and further develop his account of the (...) mind’s unity. Unity—not activity—is the best way for Berkeley to establish his view at the expense of his panpsychist competitors. (shrink)

I address an apparent conflict between Spinoza’s concepts of immanent causation and acting/doing [agere]. Spinoza apparently holds that an immanent cause undergoes [patitur] whatever it does. Yet according to his stated definition of acting and undergoing in the Ethics, this is impossible; to act is to be an adequate cause, while to undergo is to be merely a partial cause. Spinoza also seems committed to God’s being the adequate cause of all things, and, in a well-known passage, appears to deny (...) categorically that God is capable of undergoing. How then can God also be the immanent cause of all things, as Spinoza claims? On the basis of a close reading of the passage in question, I argue that Spinoza actually distinguishes between two senses of undergoing. An immanent cause undergoes not by being a partial cause but rather by being the metaphysical subject of its effect. While this sense of undergoing has its roots in scholasticism, Spinoza’s willingness to attribute such a capacity to undergo to God is idiosyncratic and reveals important ways in which his understanding of essence, perfection, and causation differs from the scholastic model.

In this paper we compare two different notions of 'power', both of which attempt to provide a realist understanding of quantum mechanics grounded on the potential mode of existence. For this propose we will begin by introducing two different notions of potentiality present already within Aristotelian metaphysics, namely, irrational potentiality and rational potentiality. After discussing the role played by potentiality within classical and quantum mechanics, we will address the notion of causal power which is directly related to irrational potentiality and (...) has been adopted by many interpretations of QM. We will then present the notion of immanent power which relates to rational potentiality and argue that this new concept presents important advantages regarding the possibilities it provides for understanding in a novel manner the theory of quanta. We end our paper with a comparison between both notions of 'power', stressing some radical differences between them. (shrink)

In this paper, through a close reading of Spinoza's use of common notions I argue for the role of experiential and experimental knowledge in Spinoza's epistemology.

Conception and causation are fundamental notions in Spinoza's metaphysics. I argue against the orthodox view that, due to the causal axiom, if one thing is conceived through another thing, then the second thing causes the first thing. My conclusion forces us to rethink Spinoza's entitlement to some of his core commitments, including the principle of sufficient reason, the parallelism doctrine and the conatus doctrine.

This article aims to study the intersection between critical realism and complexity theories through the existing literature on complex systems via an engagement with Luhmann’s autopoiesis. With reference to the philosophies of substance and persistence, I build on previous critical realist scholarship and provide an explanation for what the literature has only noted as the limitations and potentials of autopoiesis for complex systems thinking and its compatibility with Critical Realism. By highlighting how Luhmann’s autopoiesis is not a trans-immanent/ perdurantist-exdurantist system, (...) I show first how a trans immanent system through the method of calibration entails a complex causation involving objects in the environment of systems and not just within their boundaries. Second, I explain how a trans-immanent system fits with CR via the Morphogenetic Régulation framework by exploring the theme of crisis in terms of the movement from inadequate to adequate understanding of objects.

In this paper we provide a general account of the causal models which attempt to provide a solution to the famous measurement problem of Quantum Mechanics. We will argue that—leaving aside instrumentalism which restricts the physical meaning of QM to the algorithmic prediction of measurement outcomes—the many interpretations which can be found in the literature can be distinguished through the way they model the measurement process, either in terms of the efficient cause or in terms of the final cause. We (...) will discuss and analyze why both, ‘final cause’ and ‘efficient cause’ models, face severe difficulties to solve the measurement problem. In contradistinction to these schemes we will present a new model based on the immanent cause which, we will argue, provides an intuitive understanding of the measurement process in QM. (shrink)

There is a long tradition of reading Spinoza as committed, perhaps unwillingly, to the non-reality of finite modes. While acknowledging that Spinoza does seem to rely on the reality of modes in certain places, Michael Della Rocca has called attention to what he labels an “idealist strand.” As a concluding remark in “Steps Toward Eleaticism in Spinoza's Philosophy of Action,” he claims that faced with these two conflicting strands, which are genuinely to be found in the text, it is better (...) to note both rather than artificially imposing a unity on the text. In this paper, I suggest that one need not admit two conflicting strands in Spinoza, on the one hand, nor arbitrarily disregard one strand, on the other. Rather, I argue for a unified view that diagnoses what gives rise to both seemingly conflicting strands. The key to this enterprise is recognizing that finite modes, paradoxically seeming perhaps at first, are not wholly finite. That is, a finite mode is determined by the totality of finite modes—wherein lies its finite aspect, but at the same time, and equally, partially actively determines this totality—wherein lies its infinite aspect.

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.

Spinoza's doctrine of the eternity of the mind is often understood as the claim that the mind has a part that is eternal. I appeal to two principles that Spinoza takes to govern parthood and causation to raise a new problem for this reading. Spinoza takes the composition of one thing from many to require causal interaction among the many. Yet he also holds that eternal things cannot causally interact, without mediation, with things in duration. So the human mind, since (...) it is the idea of a body existing in duration, cannot have an eternal part. In order to solve this problem, I propose an aspectual reading of Spinoza's doctrine of the eternity of the mind: the mind itself is eternal, under one of its aspects. (shrink)

Imagination is characterized by Spinoza as the first kind of knowledge, and, as such, imagination is a mode of thought. However, in a further mapping of the concept in the Ethics, we see that it is an activity that involves both the mind and the extended body. The standard and idealist interpretation of imagination does not account for its corporeal or extended dimension, leaving aside an important aspect of the activity. Based on the thesis of causal independency of attributes, I (...) will argue against the traditional interpretation and demonstrate that there is an imagination of the body in Spinoza. (shrink)
