Benedict de Spinoza is one of the most controversial and enigmatic thinkers in the history of philosophy. His greatest work, Ethics (1677), developed a comprehensive philosophical system and argued that God and Nature are identical. His scandalous Theological-Political Treatise (1670) provoked outrage during his lifetime due to its biblical criticism, anticlericalism, and defense of the freedom to philosophize. Together, these works earned Spinoza a reputation as a singularly radical thinker. -/- In this book, Steinberg and Viljanen offer a concise (...) and up-to-date account of Spinoza’s thought and its philosophical legacy. They explore the full range of Spinoza’s ideas, from politics and theology to ontology and epistemology. Drawing broadly on Spinoza’s impressive oeuvre, they have crafted a lucid introduction for readers unfamiliar with this important philosopher, as well as a nuanced and enlightening study for more experienced readers.

ABSTRACT:Technological advances introduce the possibility that, in the future, firms will be able to use big-data analysis to discover and offer consumers their individual reservation price. This can generate some interesting benefits, such as a better state of affairs in terms of equality of both welfare and resources, as well as increased social welfare. However, these benefits are countered by considerations of relational equality. This article takes up the market-failures approach as its basis to demonstrate what is wrong with using (...) big data to personalize prices. The article offers an improvement to the market-failures approach and argues that what is wrong with using big data to personalize prices is that it unfairly undermines consumers’ ability to benefit from the market, which is the very point of having a market.

According to tradition, logic is normative for reasoning. Gilbert Harman challenged the view that there is any straightforward connection between logical consequence and norms of reasoning. Authors including John MacFarlane and Hartry Field have sought to rehabilitate the traditional view. I argue that the debate is marred by a failure to distinguish three types of normative assessment, and hence three ways to understand the question of the normativity of logic. Logical principles might be thought to provide the reasoning agent with (...) first-personal directives; they might be thought to serve as third-personal evaluative standards; or they might underwrite our third-personal appraisals of others whereby we attribute praise and blame. I characterize the three normative functions in general terms and show how a failure to appreciate this threefold distinction has led disputants to talk past one another. I further show how the distinction encourages fruitful engagement with and, ultimately, resolution of the question. (shrink)

Daniel and Frances Howard-Snyder suggest that it is possible for an omnipotent being, Jove, to create randomly a world from a continuum of ever more perfect possible worlds. They then go on to argue that Jove could be characterized as morally unsurpassable despite creating a surpassable world. I raise a number of problems for the view that Jove could be characterized as morally unsurpassable when he creates (randomly or not) a surpassable world.

It is generally agreed that dispositions cannot be analyzed in terms of simple subjunctive conditionals (because of what are called “masked dispositions” and “finkish dispositions”). I here defend a qualified subjunctive account of dispositions according to which an object is disposed to Φ when conditions C obtain if and only if, if conditions C were to obtain, then the object would Φ ceteris paribus . I argue that this account does not fall prey to the objections that have been raised (...) in the literature. (shrink)

This article offers an overview of inferential role semantics. We aim to provide a map of the terrain as well as challenging some of the inferentialist’s standard commitments. We begin by introducing inferentialism and placing it into the wider context of contemporary philosophy of language. §2 focuses on what is standardly considered both the most important test case for and the most natural application of inferential role semantics: the case of the logical constants. We discuss some of the (alleged) benefits (...) of logical inferentialism, chiefly with regards to the epistemology of logic, and consider a number of objections. §3 introduces and critically examines the most influential and most fully developed form of global inferentialism: Robert Brandom’s inferentialism about linguistic and conceptual content in general. Finally, in §4 we consider a number of general objections to IRS and consider possible responses on the inferentialist’s behalf. (shrink)

This paper explores an apparent tension between two widely held views about logic: that logic is normative and that there are multiple equally legitimate logics. The tension is this. If logic is normative, it tells us something about how we ought to reason. If, as the pluralist would have it, there are several correct logics, those logics make incompatible recommendations as to how we ought to reason. But then which of these logics should we look to for normative guidance? I (...) argue that inasmuch as pluralism draws its motivation from its ability to defuse logical disputes—that is, disputes between advocates of rival logics—it is unable to provide an answer: pluralism collapses into monism with respect to either the strongest or the weakest admissible logic.

A significant portion of the practice of medicine is dependent on individual acts of medical altruism. Many of these acts, such as the donation of blood, gametes, stem cells, and organs, entail varying degrees of bodily intrusion and, for the altruist, various combinations of discomfort, risk, and expense. Discussion of the ethics of altruism has typically been fragmented under various rubrics such as blood donation, organ and tissue transplantation, health information, and the assisted reproductive technologies. The ethics of these specific (...) examples of altruism are best explored in conjunction with a broader discussion of their relatively neglected mother discipline, altruism in medicine.David Steinberg, M.D., is a board certified internist, hematologist, and oncologist. He is Chief of the Section of Medical Ethics at the Lahey Clinic Medical Center in Burlington, Massachusetts, and Clinical Assistant Professor of Medicine at the Harvard Medical School.FootnotesThis work was made possible by a grant in memory of Harold Karp by the Karp Family Foundation.

Epistemic utility theory is generally coupled with veritism. Veritism is the view that truth is the sole fundamental epistemic value. Veritism, when paired with EUT, entails a methodological commitment: norms of epistemic rationality are justified only if they can be derived from considerations of accuracy alone. According to EUT, then, believing truly has epistemic value, while believing falsely has epistemic disvalue. This raises the question as to how the rational believer should balance the prospect of true belief against the risk (...) of error. A strong intuitive case can be made for a kind of epistemic conservatism – that we should disvalue error more than we value true belief. I argue that none of the ways in which advocates of veritist EUT have sought to motivate conservatism can be squared with their methodological commitments. Short of any such justification, they must therefore either abandon their most central methodological principle or else adopt a permissive line with respect to epistemic risk. (shrink)

Spinoza's account of belief entails that if A has two ideas, p and q, with incompatible content, A believes that p if the idea of p is stronger than the idea of q. This seems to leave little space for dominant non-beliefs, or cases in which there is discord between one's beliefs and one's affective-behavioral responses. And yet Spinoza does allow for two classes of dominant non-beliefs: efficacious fictions [fictiones] and ideas that conduce to akrasia. I show how Spinoza can (...) account for dominant non-beliefs within his model of cognition by distinguishing between the doxastic and the affective powers of ideas and by suggesting that doxastic power is best understood diachronically. While other scholars have stressed the elegance of Spinoza's account of ideas, this paper highlights the sophistication and flexibility of his account. (shrink)

We consider and reject a variety of attempts to provide a ground for identifying and differentiating disembodied minds. Until such a ground is provided, we must withhold inclusion of disembodied minds from our picture of the world.

Fritz Allhoff has recently offered an extremely compelling challenge to the morality of human cloning. He argues that a biological phenomenon, that of telomere shortening, undermines the moral permissibility of human cloning. Telomere shortening is caused by cell replication, and appears to be one of the central reasons that cells and organisms age and die. Allhoff considers a thirty-year-old woman who wishes to create a genetic clone. He notes that the DNA from her cell that would be used to create (...) the clone would have shortened telomeres—as it would have gone through many generations of cell replication. As a result, the clone would begin its existence with shortened telomeres; the clone’s telomeres would be the same length as the woman’s telomeres at the time of cloning. The moral problem lies in the fact that because of shortened telomeres, the clone will senesce more rapidly as compared with noncloned organisms, and would have increased susceptibility to degenerative conditions and diseases. Allhoff then goes on to argue that earlier senescence and disease susceptibility constitute a moral ground for rejecting cloning because “the life of a clone would be worse than that of a non-clone”. This line of argument is rooted in Parfit’s The Same Number Quality Claim : “If in either of two outcomes the same number of people would ever live, it would be bad if those who live are worse off, or have a lower quality of life, than those who would have lived”. Applying Parfit’s Q principle to cases of cloning, it could be argued that parents ought to produce children that would be maximally well off, and since clones would be worse off than children produced “normally,” it follows that parents should avoid cloning. As Allhoff puts it, “obviously sexual reproduction would not transfer shortened telomeres to offspring so, all else being equal, sexual reproduction is better than cloning ”. For this sort of line to pack any moral punch, Q must be interpreted rather strongly. (shrink)

A landmark of Enlightenment thought, Hume's _An Enquiry Concerning Human Understanding_ is accompanied here by two shorter works that shed light on it: _A Letter from a Gentleman to His Friend in Edinburgh_, Hume's response to those accusing him of atheism, of advocating extreme skepticism, and of undermining the foundations of morality; and hisof _A Treatise of Human Nature_, which anticipates discussions developed in the _Enquiry_. In his concise Introduction, Eric Steinberg explores the conditions that led Hume to write (...) the Enquiry and the work's important relationship to Book I of Hume's _A Treatise of Human Nature_.

In recent years, insurance companies have begun tracking their customers’ behaviors and price premiums accordingly. Based on the Market-Failures Approach as well as the Justice-Failures Approach, I provide an ethical analysis of the use of tracking technologies in the insurance industry. I focus on the use of telematics in car insurance and on the use of fitness tracking in life insurance. The use of tracking has some important benefits to policyholders and insurers alike: it reduces moral hazard and fraud, increases (...) actuarial fairness, and incentivizes safe behavior. These benefits, however, are outweighed by significant moral objections. First, the use of tracking technologies significantly undermines the fairness of the interaction between insurance companies and policyholders. Specifically, the use of tracking eliminates information asymmetries, but in such a way that favors insurers exclusively. Furthermore, tracked behaviors and the ability to choose to behave safely are highly correlated with other variables such as income. Therefore, tracking-based insurance relies on and exacerbates existing inequalities and injustices, which undermines the benefits that tracking is supposed to introduce. (shrink)

For a half-century or more, political theory has been characterized by a pronounced distrust of metaphysical or ontological speculation. Such a disposition has been sharply at odds with influential currents in post-war philosophy - both analytic and continental - where metaphysical issues have become a central preoccupation. The Idea of the State seeks to reaffirm the importance of systematic philosophical inquiry into the foundations of political life, and to show how such an approach can cast a new and highly instructive (...) light on a variety of controversial, seemingly intractable problems of tolerance, civil disobedience, democracy and consent. The author considers the problem of the state in light of recent developments in philosophy and social thought, and seeks to provide an account of what the state really is. In doing so he pursues a range of fundamental issues pertaining to the office, the authority and the internal organization of political society. (shrink)

In this paper, I maintain—contrary to those commentators who regard him as a principled republican—that at the core of Spinoza’s political theory is an instrumental, rather than an intrinsic, defense of democratic procedures. Specifically, Spinoza embraces democratic decision procedures primarily because they tend to result in better decisions, defined relative to a procedure-independent standard of correctness or goodness. In contemporary terms, Spinoza embraces an epistemic defense of democracy. I examine Spinoza’s defense of collective governance, showing not only how it differs (...) from other accounts of his time but also how it might contribute to current debates about the epistemic standing of popular governing bodies. In the opening section I defend the thesis that has been contested in recent years that Spinoza was, in fact, a consistent democrat. The second section focuses on procedural (i.e., intrinsic) defenses of democracy, paying particular attention to the republican version of proceduralism that was prominent in Spinoza’s time. And in the final section I present my case for reading Spinoza as an epistemic democrat, comparing his epistemic defense with contemporary versions. What we find are not only striking anticipations of contemporary arguments, but also largely neglected lines of argumentation that reveal both the potential epistemic advantages and disadvantages of democracy.

In this essay I consider what grounds Spinoza’s defense of the freedom to philosophize, considering why Spinoza doesn’t think that we should attempt to snuff out irrationality and dissolution with the law’s iron fist. In the first section I show that Spinoza eschews skeptical, pluralistic, and rights-based arguments for toleration. I then delineate the prudential, anticlerical roots of Spinoza’s defense, before turning in the final section to consider just how far and when toleration contributes to the guiding norms of governance: (...) peace and empowerment. Once we see how the defense of toleration is anchored in these norms, we form a clearer picture of Spinoza as a liberal perfectionist for whom the bounds of political toleration depends on pragmatic and circumstance-specific assessments of what conduces to the flourishing of the state. This will help to illuminate what is distinctive—and, perhaps, distinctively commendable—about Spinoza’s form of liberalism. (shrink)

An important motivation for believing in the modal realist’s ontology of other concrete possible worlds and their inhabitants is its theoretical utility, centrally the reduction of ordinary modal talk to counterpart theory as showcased by David Lewis’s 1968 translation scheme. In a recent paper Harold Noonan, following the lead of John Divers, argues that Lewis’s scheme is not strictly adequate by the modal realist’s own lights, and that nothing short of jettisoning de dicto contingency will help. In this paper, I (...) argue that this is a serious overreaction. First, I show that Noonan’s problem does not touch Lewis’s proposal, since his translation scheme is not even concerned with the relevant sentences. Thus, Noonan’s problem only points to a limit in scope. I then go on to propose a straightforward extension of the translation scheme that provides translations for the allegedly problematic sentences, but does so endangering neither adequacy nor de dicto contingency.

Spinoza's Political Psychology advances a novel, comprehensive interpretation of Spinoza's political writings, exploring how his analysis of psychology informs his arguments for democracy and toleration. Justin Steinberg shows how Spinoza's political method resembles the Renaissance civic humanism in its view of governance as an adaptive craft that requires psychological attunement. He examines the ways that Spinoza deploys this realist method in the service of empowerment, suggesting that the state can affectively reorient and thereby liberate its citizens, but only if (...) it attends to their actual motivational and epistemic capacities. His book will interest a range of readers in Spinoza studies and the history of political thought, as well as readers working in contemporary political theory. (shrink)

In the Ethics, Spinoza advances two apparently irreconcilable construals of will [voluntas]. Initially, he presents will as a shorthand way of referring to the volitions that all ideas involve, namely affirmations and negations. But just a few propositions later, he defines it as striving when it is “related only to the mind” (3p9s). It is difficult to see how these two construals can be reconciled, since to affirm or assent to some content is to adopt an attitude with a cognitive (...) (mind-to-world) direction of fit, while to strive to persevere in one’s being would seem to be to adopt an attitude with a conative (world-to-mind) direction of fit. Attempting to achieve consistency by taking striving under the attribute of thought to consist in affirming only pushes the equivocation problem onto the concept of affirmation (Lin 2019). It would seem, then, that Spinoza equivocates on the concepts of will, affirmation, or perhaps both. I defend the univocity of Spinoza’s accounts of will and affirmation, showing that it comports with established accounts of affirmation in early modern philosophy and yields a clear, uniform account of what it means to strive under the attribute of thought, preserving the systematicity of Spinoza’s account of mind in ways that other interpretations do not.

Logic, the tradition has it, is normative for reasoning. But is that really so? And if so, in what sense is logic normative for reasoning? As Gilbert Harman has reminded us, devising a logic and devising a theory of reasoning are two separate enterprises. Hence, logic's normative authority cannot reside in the fact that principles of logic just are norms of reasoning. Once we cease to identify the two, we are left with a gap. To bridge the gap one would (...) need to produce what John MacFarlane has appropriately called a bridge principle, i.e. a general principle articulating a substantive and systematic link between logical entailment and norms of reasoning. This is Harman's skeptical challenge. In this paper I argue that Harman's skeptical challenge can be met. I show how candidate bridge principles can be systematically generated and evaluated against a set of well‐motivated desiderata. Moreover, I argue that bridge principles advanced by MacFarlane himself and others, for all their merit, fail to address the problem originally set forth by Harman and so do not meet the skeptical challenge. Finally, I develop a bridge principle that meets Harman's requirements as well as being substantive. (shrink)

In this paper I examine the question of logic’s normative status in the light of Carnap’s Principle of Tolerance. I begin by contrasting Carnap’s conception of the normativity of logic with that of his teacher, Frege. I identify two core features of Frege’s position: first, the normative force of the logical laws is grounded in their descriptive adequacy; second, norms implied by logic are constitutive for thinking as such. While Carnap breaks with Frege’s absolutism about logic and hence with the (...) notion that any system of logic should have a privileged claim to correctness, I argue that there is a sense in which Carnap’s framework-relative conception of logical norms has a constitutive role to play: though they are not constitutive for the conceptual activity for thinking, they do nevertheless set the ground rules that make certain forms of scientific inquiry possible in the first place. I conclude that Carnap’s principle of tolerance is tamer than one might have thought and that, despite remaining differences, Frege’s and Carnap’s conceptions of logic have more in common than one might have thought.

Despite Spinoza’s reputation as a thoroughgoing critic of teleology, in recent years a number of scholars have argued convincingly that Spinoza does not wish to eliminate teleological explanations altogether. Recent interpretative debates have focused on a more recalcitrant problem: whether Spinoza has the resources to allow for the causal efficacy of representational content. In this paper I present the problem of mental causation for Spinoza and consider two recent attempts to respond to the problem on Spinoza’s behalf. While these interpretations (...) certainly shed some light on Spinoza’s account of cognitive economy, I argue that both fail to point the way out of the problem because they fail to differentiate between two forms of representation, one of which is causally efficacious, one of which is not. I close by suggesting that there is some reason to believe that Spinoza’s account of mind avoids some of the problems typically associated with mental causation. (shrink)

Logic has traditionally been construed as a normative discipline; it sets forth standards of correct reasoning. Explosion is a valid principle of classical logic. It states that an inconsistent set of propositions entails any proposition whatsoever. However, ordinary agents presumably do — occasionally, at least — have inconsistent belief sets. Yet it is false that such agents may, let alone ought to, believe any proposition they please. Therefore, our logic should not recognize explosion as a logical law. Call this the (...) ‘normative argument against explosion’. Arguments of this type play — implicitly or explicitly — a central role in motivating paraconsistent logics. Branden Fitelson, in a throwaway remark, has conjectured that there is no plausible ‘bridge principle’ articulating the normative link between logic and reasoning capable of supporting such arguments. This paper offers a critical evaluation of Fitelson’s conjecture, and hence of normative arguments for paraconsistency and the conceptions of logic’s normative status on which they repose. It is argued that Fitelson’s conjecture turns out to be correct: normative arguments for paraconsistency probably fail. (shrink)

As philosophers are keen to say, there is a possible world where Socrates is a carpenter. Plausibly, truths about what might or could not be the case are not basic but grounded in more fundamental features of reality. Steinberg develops this insight into a novel account of the supervenience structure of the modal realm. This study was awardedthe 2012 GAP/ontos award.".

In defending the scientific legitimacy of ceteris paribus qualified causal generalizations, we situate and specify the reference of the ceteris paribus proviso within a fundamental causal framework consisting of causal agents, pathways of influence, mediators, moderators, and causal consequences. In so doing, we provide an explication of the reference and utility of the ceteris paribus proviso in terms of mediators and moderators as these constitute the range of factors that can impinge on the relation between cause and effect. We argue (...) that the conceptual causal roadmap embodied by the ceteris paribus qualification serves as a schematic template for the ongoing identification of causally relevant factors and plays an indispensable heuristic role in advancing scientific inquiry into causal relations. We then provide guidelines for differentiating between acceptable and unacceptable uses of ceteris paribus and describe how mediators and moderators conceptually encompassed by the ceteris paribus proviso can be employed in evaluating the meaning and acceptability of proposed ceteris paribus causal generalizations, as well serve as a guide to investigators in the process of designing studies to identify a causal agent, mediators, moderators, pathways of influence, and causal consequences. 2012 APA, all rights reserved).

Spinoza’s treatment of absolute sovereignty raises a number of interpretative questions. He seems to embrace a form of absolutism that is incompatible with his defense of mixed government and constitutional limits on sovereign power. And he seems to use the concept of “absolute sovereignty” in inconsistent ways. I offer an interpretation of Spinoza’s conception of absolutism that aims to resolve these problems. I argue that Spinoza is able to show that, when tied to a proper understanding of authority, absolute sovereignty (...) is not only compatible with, but actually necessitates, power-sharing and constitutionalism.

This chapter considers the challenges to, and the resources for, cultivating a personal capacity for tolerance, given a Spinozist account of belief-formation. After articulating two main components of personal tolerance, I examine the features of Spinoza’s theory of cognition that make the cultivation of tolerance so difficult. This is followed by an analysis of Spinoza’s account of overcoming intolerant tendencies. Ultimately, I argue that the capacity of individuals to be tolerant depends crucially on the establishment of conditions of trust, conditions (...) that are conspicuously lacking in many modern democracies.

It is often noted that Spinoza’s conception of striving (conatus) reflects the influence of Hobbes. While this is undoubtedly true, in this chapter I explore how an important difference in how Hobbes and Spinoza understand “striving” drives a wedge between them, resulting in remarkably different views of goodness, happiness, liberty, and the function of the state.

In recent years, a number of commentators have expressed dissatisfaction with Spinoza’s account of practical reason. In this paper, I defend his account against the most prominent objections, showing that the dictates of reason play an important role in guiding thought and action. However, against the standard interpretation, I propose that we view these rules not as exceptionless, instrumental prescriptions—hypothetical imperatives with necessary antecedents, as Curley memorable put it—but rather as adaptable guideposts that aid us in the complex, dynamic process (...) of acquiring a habit of virtue. The dictates of reason are best understood as defeasible policies that help to orient one in the ars vivendi. (shrink)

In my Steinberger 2009 I argued that Neil Tennant’s Harmony requirement is untenable because of its failure to account for the standard quantifier rules.1 Instead of justifying the customary rules for the existential and universal quantifiers, Tennant’s account appears to sanction only wholly unrestricted – and so patently disharmonious – quantifier rules. In his characteristically thoughtful response Tennant 2010, Tennant offers a sequent calculus version of his Harmony requirement that rules out such pathological would-be quantifiers. While I agree with Tennant (...) that recasting his Harmony requirement in the sequent format as he proposes blocks the said disharmonious quantifier rules, I submit that Tennant’s revamped Harmony requirement nevertheless misses the mark. I present two objections to substantiate my claim. First, I show that the crucial additional assumption underlying Tennant’s sequent calculus-based account – what I call the admissibility assumption – is excessively strong: so strong, in fact, that it renders otiose the core of Tennant’s original account. Second, I argue that the admissibility assumption, as a global requirement on deductive systems, is ill-suited for the purposes of codifying the intuitive notion of harmony. Fortunately, though, as I will demonstrate, we can dispense with the admissibility assumption altogether. (shrink)

Modern political conflict characteristically reflects and represents deep-seated but also unacknowledged and un-analyzed disagreements about what it means to be 'objective'. In defending this proposition, Peter J. Steinberger seeks to reaffirm the idea of rationalism in politics by examining important problems of public life explicitly in the light of established philosophical doctrine. The Politics of Objectivity invokes, thereby, an age-old, though now widely ignored, tradition of western thought according to which all political thinking is inevitably embedded in and underwritten by (...) larger structures of metaphysical inquiry. Building on earlier studies of the idea of the state, and focusing on highly contested practices of objectivity in judgement, this book suggests that political conflict is an essentially discursive enterprise deeply implicated in the rational pursuit of theories about how things in the world really are.

In this paper I maintain that Spinoza systematizes independently credible accounts of belief-formation, affect, and desire into an intriguing general theory of how the mind works. His account also explains disparate downstream psychological phenomena, including: (1) emotional responses to fiction; (2) belief perseverance; (3) the reduction of cognitive dissonance; (4) epistemic conservativism that opens us up to confirmation bias, identity protection, and intolerance. Given the promise of Spinoza’s program, I conclude with a plea for further philosophical engagement.

I would have preferred that the Special Section on Children as Organ Donors had focused on the donation of a specific organ because morally relevant differences are obscured when the subject is discussed in general terms. The donation of a lobe of liver and peripheral blood or bone marrow stem cells does not result in the permanent loss of vital tissue because these organs regenerate; however, a kidney does not regenerate and its donor loses a vital organ permanently. Liver tissue (...) and peripheral blood or bone marrow stem cells are typically required to save a life, but, because most patients with end-stage renal disease can be kept alive on dialysis, the donation of a kidney is rarely life saving. Also, donor risk is organ specific; for example, it is more dangerous to donate a lobe of liver than it is to donate peripheral blood or bone marrow stem cells. (shrink)
