This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

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.

Over the last quarter century, the dominant tendency in comparative cognitive psychology has been to emphasize the similarities between human and nonhuman minds and to downplay the differences as (Darwin 1871). In the present target article, we argue that Darwin was mistaken: the profound biological continuity between human and nonhuman animals masks an equally profound discontinuity between human and nonhuman minds. To wit, there is a significant discontinuity in the degree to which human and nonhuman animals are able to approximate (...) the higher-order, systematic, relational capabilities of a physical symbol system (PSS) (Newell 1980). We show that this symbolic-relational discontinuity pervades nearly every domain of cognition and runs much deeper than even the spectacular scaffolding provided by language or culture alone can explain. We propose a representational-level specification as to where human and nonhuman animals' abilities to approximate a PSS are similar and where they differ. We conclude by suggesting that recent symbolic-connectionist models of cognition shed new light on the mechanisms that underlie the gap between human and nonhuman minds. (shrink)

How many people should there be? Can there be overpopulation: too many people living? I shall present a puzzling argument about these questions, show how this argument can be strengthened, then sketch a possible reply.

When Ingmar and I discuss metaphysics or morality, our views are seldom far apart. Hut on the subjects of this paper, rationality and reasons, we deeply disagree.

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)

This article discusses the relation between prioritarian and egalitarian principles, whether and why we need to appeal to both kinds of principle, how prioritarians can answer various objections, especially those put forward by Michael Otsuka and Alex Voorhoeve, the moral difference between cases in which our acts could affect only one person or two or more people, veil of ignorance contractualism and utilitarianism, what prioritarians should claim about cases in which the effects of our acts are uncertain, the relative moral (...) importance of actual and expectable benefits, whether people should sometimes be given various chances of receiving benefits, and principles that appeal to competing claims.

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)

We can start with some science fiction. Here on Earth, I enter the Teletransporter. When I press some button, a machine destroys my body, while recording the exact states of all my cells. The information is sent by radio to Mars, where another machine makes, out of organic materials, a perfect copy of my body. The person who wakes up on Mars seems to remember living my life up to the moment when I pressed the button, and he is in (...) every other way just like me. Of those who have thought about such cases, some believe that it would be I who would wake up on Mars. They regard Teletransportation as merely the fastest way of travelling. Others believe that, if I chose to be Teletransported, I would be making a terrible mistake. On their view, the person who wakes up would be a mere Replica of me. (shrink)

sonable, in this sense, if we ignore, or give too little weight to, some other people's well-being or moral claims.' Some critics have suggested that, because Scanlon appeals to this sense of 'reasonable', his formula is empty. On this objection, whenever we believe that some act is wrong, we shall believe that people have moral claims not to be treated in this way. We could therefore argue that such acts are disallowed by some principle which no one could reasonably reject, (...) since anyone who rejected this principle would be giving too little weight to people's moral claims not to be treated in this way. Since everyone could claim that the principles which they accept could not be reasonably rejected, Scanlon's Formula would make no difference to our moral thinking. That is not so. If we reject the principles that disallow certain acts, we are denying that such acts are wrong. This denial would be unreasonable if it would give too little weight to some other people's moral claims. So Scanlon's Formula implies that.. (shrink)

Suppose that we can help either one person or many others. Is it a reason t0 help the many that We should thus be helping more people? John Taurek thinks not. We may learn from his arguments.

Much recent work on empathy assumes that one cannot give non-question-begging reasons for empathizing with others. In this article I argue that there are epistemic reasons for cultivating empathy. After sketching a brief general account of empathy, I proceed to argue that empathic information is user-friendly, fostering the achievement of widely held cognitive goals. It can also contribute to social knowledge and the satisfaction of democratic ideals. The upshot of my analysis is that there are strong, but defeasible, epistemic reasons (...) for empathizing with others. (shrink)

In IVP50S, Spinoza claims that “one who is moved to aid others neither by reason nor by pity is rightly called inhuman. For (by IIIP27) he seems to be unlike a man” (IVP50S). At first blush, the claim seems implausible, as it relies on the dubious assumption that beings will necessarily imitate the affects of conspecifics. In the first two sections of this paper, I explain why Spinoza accepts this thesis and show how this claim can be made compatible with (...) his account of representation. In the third and final section I offer an auxiliary defense of the thesis, showing that, according to Spinoza, to be human is to sociable, and sociability depends on the imitation of the affects.

In this paper, I argue that Spinoza’s political theory gives us a model for how he might have approached a treatise on moral education. Indeed, his account of the method and aims of politics resembles Renaissance humanist rhetorical approaches to pedagogy – particularly, the work of sixteenth century Spanish humanist Juan Luis Vives – so strongly that it is hardly an exaggeration conclude that, for him, politics is education writ large. For Spinoza and for Vives, the governor-or-instructor must study the (...) prevailing character, or ingenium, of the subject and adopt means that promote the cognitive and emotional development of the subject, which can be accomplished only to the extent that subjects willingly participate in their own governance-or-instruction. Spinoza joins this rhetorical procedure to a Hobbesian scientific approach to studying ingenia, resulting in a political method that is part science, part art. (shrink)

In part I of this paper I argue that on his theory of the mind as the idea of an actually existing body Spinoza is unable to account for the ability of the mind to have adequate knowledge, and I suggest that his theory of the eternity of the mind can be viewed as his solution to this problem. In part II I deal with the question of the meaning of ‘eternity’ in Spinoza, in regard both to God and the (...) human mind, and I sketch a line of thought which I believe may have provided him with further motivation for his theory that a part of the mind is eternal.

This introductory article provides a contextual and theoretical overview to this special issue of Body & Society. The special issue presents five selected case studies – focusing on the contexts of transplantation, psychiatry, amputation and war, and a transvalued media ecology of cancer – to offer meditations on a number of interlinked questions. The first of these is the entanglement of biomedical governance – political/economic as well as self-disciplinary – with the nexus of estrangement, which can denote both the distancing (...) of otherness and self-division. Second is the realm of feeling, of phantasmatic projection and of the ways in which the biopolitical becomes reciprocally, discursively, enmeshed in a wider cultural imaginary. Third is the shifting terrain of gender and feminist politics, a key dimension of which is the necessary reworking of feminist thought in the wake of a radically altered biomedical and biotechnological landscape. Under the rubric of Estranged Bodies, the collection considers themes of dissolution and the fragility of the body/subject read through bodily catastrophe, radical body modification and extreme medical intervention. Also considered is the notion of assemblage – the provisional coming together of disparate parts – which encourages a rethinking of questions of reconstituted, displaced and re-placed bodies.

Spinoza's use of the phrase “sui iuris” in the Tractatus Politicus gives rise to the following paradox. On the one hand, one is said to be sui iuris to the extent that one is rational; and to the extent that one is rational, one will steadfastly obey the laws of the state. However, Spinoza also states that to the extent that one adheres to the laws of the state, one is not sui iuris, but rather stands under the power [sub (...) potestate] of the state (TP 3/5). It seems, then, that to the extent that one is sui iuris, one will not, in fact, be sui iuris. In this paper, I offer an interpretation of Spinoza's notion of being sui iuris that enables us to overcome this paradox and sheds light on Spinoza's relationship to the republican tradition. I work towards this goal by distinguishing between two ways in which Spinoza uses the locution, which correspond to two different conceptions of power: potentia and potestas. This distinction not only allows us to save Spinoza from internal inconsistency, it also enables us to see one important way in which Spinoza stands outside of the republican tradition, since he conceives of liberty not as constituted by independence, or citizenship in a res publica, but as being sui iuris in the first sense described above: being powerful.

Two priority problems frustrate our understanding of Spinoza on desire [cupiditas]. The first problem concerns the relationship between desire and the other two primary affects, joy [laetitia] and sadness [tristitia]. Desire seems to be the oddball of this troika, not only because, contrary to the very definition of an affect, desires do not themselves consist in changes in one's power of acting, but also because desire seems at once more and less basic than joy and sadness. The second problem concerns (...) the priority of desires and evaluative judgements. While 3p9s and 3p39s suggest that evaluative judgements are posterior to desires, Andrew Youpa has recently argued that passages in Ethics 4 indicate that rational evaluative judgements can give rise to, rather than arise out of, desires. I aim to offer solutions to these problems that reveal the elegance and coherence of Spinoza's account of motivation. Ultimately, I argue that whereas emotions and d.. (shrink)

The role of possible worlds in philosophy is hard to overestimate. Nevertheless, their nature and existence is very controversial. This is particularly serious, since their standard applications depend on there being sufficiently many of them. The paper develops an account of possible worlds on which it is particularly easy to believe in their existence: an account of possible worlds as pleonastic entities. Pleonastic entities are entities whose existence can be validly inferred from statements that neither refer to nor quantify over (...) them as a matter of conceptual necessity. Definitions are proposed that ensure that this is the case for possible worlds. (shrink)

The constitutional monarchy of present-day Britain hardly seems the same sort of institution as fourteenth-century feudal kingdoms, but Dante’s Monarchia (c. 1313) and Walter Bagehot’s The English Constitution (1872) share fundamental assumptions about what the purpose and strengths of monarchy are. In the Monarchia, Dante lays out the essential attributes of monarchy that endure even today: authority, impartiality, and unity. Dante values and promotes monarchy as final arbiter of conflicts, sole just judge without cupidity, and unifying will. More than 550 (...) years later, Bagehot, despite his distrust concerning the Crown’s actual effectiveness, conceives of monarchy in surprisingly similar terms. The monarch is ‘the regulating wheel of our Constitution’, an authority outside and above partisan politics, and the ‘dignified’, ‘intelligible’, unifying element of government. In both cases, the monarch functions as the government’s source of impartial, unifying authority – whether monarch or Parliament ultimately wields that authority. The broad outlines of monarchy are surprisingly similar for both writers, suggesting a basic continuity in the conceptualization of monarchy from the fourteenth to the nineteenth century (and beyond) and an abiding store of reserve symbolism within the monarchic concept that writers, thinkers, and politicians throughout those centuries are able to tap at will.

In the final chapter of the Tractactus Theologico-Politicus , Spinoza declares that “the purpose of the state is, in reality, freedom.” While this remark obviously purports to tell us something important about Spinoza’s conception of the civitas , it is not clear exactly what is revealed. Recently, a number of scholars have interpreted this passage in a way that supports the view that Spinoza was a liberal for whom civic norms are rather more modest than the freedom of the Ethics (...) . Against this view, I provide an interpretation of Spinoza’s account of civil liberation that enables us to view the political writings as an extension of his larger ethical enterprise. Specifically, I show that, according to Spinoza, the state can promote robust liberty in a variety of ways, not least by influencing the behavioral patterns and affective dispositions of its citizens.

Given that an analysis of disposition ascription cannot be made in terms of a simple subjunctive conditional, we present a multiply qualified conditional analysis that places disposition ascription within an implicit fundamental causal conceptual typography within which a disposition ascription is embedded, framed, and understood. By placing the multiply qualified analysis within an implicit causal matrix involving a focal cause, pathway of influence, mechanism of action, contributing/partial cause, mediator, extrinsic moderator,, intrinsic moderator, and manifestation, we show how this analysis evades (...) counterexamples and arguments raised against the simple conditional analysis. We then indicate how the causal conceptual landscape provides a roadmap for unpacking and explicating parameters of the ceteris paribus qualifier to acquit the analysis of charges of being vacuous or irredeemably vague.

Leibniz argued that God would not create a world unless it was the best possible world. I defend Leibniz’s argument. I then consider whether God could refrain from creating if there were no best possible world. I argue that God, on pain of contradiction, could not refrain from creating in such a situation. I conclude that either this is the best possible world or God is not our creator.
