The paper is written in response to those who fail to recognize the relation between a patient's mental competency and her state of pain. Some clinicians claim that a proper diagnosis can only be made in the absent of analgesia. Rather, the patient's state of pain directly affects her mental competency and thus her ability to give valid consent. Clinicians should rethink their approach to diagnosis when the patient is in pain.

In this paper we suggest a revisionist perspective on two significant figures in early modern life science and philosophy: William Harvey and John Locke. Harvey, the discoverer of the circulation of the blood, is often named as one of the rare representatives of the ‘life sciences’ who was a major figure in the Scientific Revolution. While this status itself is problematic, we would like to call attention to a different kind of problem: Harvey dislikes abstraction and (...) controlled experiments (aside from the ligature experiment in De Motu Cordis), tends to dismiss the value of instruments such as the microscope, and emphasizes instead the privileged status of ‘observed experience’. To use a contemporary term, Harvey appears to rely on, and chiefly value, ‘tacit knowledge’. Secondly, Locke’s project is often explained with reference to the image he uses in the Epistle to the Reader of his Essay, that he was an “underlabourer” of the sciences. In fact, despite the significant medical phase of his career, Locke’s ‘empiricism’ turns out to be above all a practical (i.e. ‘moral’) project, which focuses on the delimitation of our powers in order to achieve happiness, and rejects the possibility of naturalizing knowledge. When combined, these two cases suggest a different view of some canonical moments in early modern natural philosophy. (shrink)

Reshaping the neo-Aristotelian doctrines about the human soul was Descartes’s most spectacular enterprise, which gave birth to some of the sharpest debates in the Republic of Letters. Neverthe- less, it was certainly Descartes’s intention, as already expressed in the Discours de la méthode, to show that his new metaphysics could be supplemented with experimental research in the field of medicine and the conservation of life. It is no surprise then that several natural philosophers and doctors, such as Henricus Regius from (...) Utrecht, who had studied in Padua with William Harvey, rallied in support, in order to gain a more substantial theoretical basis for their research. Taking as his ground some general metaphysical assumptions, such as the existence of God, the immortality of the soul, and perhaps the separability of the pure understanding, Regius intended to secure a new philosophy of man, which was able to reflect his medical interests and complement his account of human nature. This is the story that is now gaining currency, and it is surely accurate, at least in part. Desmond Clarke has recently defended the same view1, based on the remarkable studies of the Utrecht scholars Theo Verbeek and Erik-Jan Bos. Here I would like to challenge some aspects of this view and ask how Regius, who was perceived as the philosopher most closely associated with Descartes, became a betrayer of his mentor. (shrink)

There is an interesting historical detour in the dissemination of one of the seventeenth century’s most praised discoveries: the reception of Harvey’s account of the circulation of the blood is closely intertwined, especially in the Low Countries, with Descartes’ account of the origin of the heartbeat. Descartes was one of the first figures to support the circulation of the blood and to give credit to Harvey for it, although he presumably arrived at the same conclusion independently through his (...) own anatomical experiments. He did so while vocally rejecting Harvey’s views on the muscular nature of the heart and his explanation of cardiac motion, to promote his own mechanistic solutions instead. Although Descartes’ ..

ABSTRACT. This essay addresses the interpretation of Descartes’ understanding of the mind-body relationship as a substantial union in light of a statement he makes in the Passions de l’âme regarding the role of the blood and vital heat. Here, it seems Descartes cites these corporeal properties as the essential dispositions responsible for accommodating the soul into the human fetus. I argue that this statement should be read in the context of certain medical texts with which Descartes was familiar, namely those (...) of Jean Fernel and William Harvey. Reviewing Fernel’s comments on substantial union, one finds that the soul joins the body on the basis of a celestial spirit that not only bears the vital heat, it also directs the generation of the body. Similar to Harvey, Descartes locates these properties in the blood itself, although, in contrast to Harvey, Descartes reduces these processes to matter and motion. Finally, I highlight the role this heat plays in Descartes’ embryological writing, contrasting it with that of Fernel. I conclude that although Descartes makes various comments supporting a reading of the mind-body relation as a substantial union, his physiological writings on generation and his idea of ‘life’ contradict this interpretation. -/- .

The articles in the special issue "Experience in natural philosophy and medicine" discuss the roles and notions of experience in the works of a range of early modern authors, including Galileo Galilei, Francis Bacon, the Dutch atomist David Gorlaeus, William Harvey, and Christian Wolff. The articles extend the evidential basis on which we can rely to identify trends, changes and continuities in the roles and notions of experience in the period of the Scientific Revolution. They shed light on (...) the longstanding influence of traditional views and the emergence of early modern experimental philosophy. This introduction highlights the benefits of considering medicine in connection with natural philosophy when studying early modern views on experience and summarizes the articles. (shrink)

This paper was written to study the order of medical advances throughout history. It investigates changing human beliefs concerning the causes of diseases, how modern surgery developed and improved methods of diagnosis and the use of medical statistics. Human beliefs about the causes of disease followed a logical progression from supernatural causes, such as the wrath of the Gods, to natural causes, involving imbalances within the human body. The invention of the microscope led to the discovery of microorganisms which were (...) eventually identified as the cause of infectious diseases. Identification of the particular microorganism causing a disease led to immunization against the disease. Modern surgery only developed after the ending of the taboo against human dissection and the discovery of modern anesthesia and the discovery of the need for anti-septic practices. Modern diagnostic practices began with the discovery of x-rays and the invention of medical scanners. Improved mathematics, especially in probability theory, led to statistical studies which led to a much greater ability, to identify the causes of disease, and to evaluate the effectiveness of treatments. These discoveries all occurred in a necessary and inevitable order with the easiest discoveries being made first and the harder discoveries being made later. The order of discovery determined the course of the history of medicine and is an example of how social and cultural history has to follow a particular course determined by the structure of the world around us.

I present a new puzzle about choice under uncertainty for agents whose preferences are sensitive to multiple dimensions of outcomes in such a way as to be incomplete. In response, I develop a new theory of choice under uncertainty for incomplete preferences. I connect the puzzle to central questions in epistemology about the nature of rational requirements, and ask whether it shows that preferences are rationally required to be complete.

The coordinated attack scenario and the electronic mail game are two paradoxes of common knowledge. In simple mathematical models of these scenarios, the agents represented by the models can coordinate only if they have common knowledge that they will. As a result, the models predict that the agents will not coordinate in situations where it would be rational to coordinate. I argue that we should resolve this conflict between the models and facts about what it would be rational to do (...) by rejecting common knowledge assumptions implicit in the models. I focus on the assumption that the agents have common knowledge that they are rational, and provide models to show that denying this assumption suffices for a resolution of the paradoxes. I describe how my resolution of the paradoxes fits into a general story about the relationship between rationality in situations involving a single agent and rationality in situations involving many agents.

Robert Aumann presents his Agreement Theorem as the key conditional: “if two people have the same priors and their posteriors for an event A are common knowledge, then these posteriors are equal” (Aumann, 1976, p. 1236). This paper focuses on four assumptions which are used in Aumann’s proof but are not explicit in the key conditional: (1) that agents commonly know, of some prior μ, that it is the common prior; (2) that agents commonly know that each of them updates (...) on the prior by conditionalization; (3) that agents commonly know that if an agent knows a proposition, she knows that she knows that proposition (the “K K” principle); (4) that agents commonly know that they each update only on true propositions. It is shown that natural weakenings of any one of these strong assumptions can lead to countermodels to Aumann’s key conditional. Examples are given in which agents who have a common prior and commonly know what probability they each assign to a proposition nevertheless assign that proposition unequal probabilities. To alter Aumann’s famous slogan: people can “agree to disagree”, even if they share a common prior. The epistemological significance of these examples is presented in terms of their role in a defense of the Uniqueness Thesis: If an agent whose total evidence is E is fully rational in taking doxastic attitude D to P, then necessarily, any subject with total evidence E who takes a different attitude to P is less than fully rational.

I observe that the “concept-generator” theory of Percus and Sauerland (2003), Anand (2006), and Charlow and Sharvit (2014) does not predict an intuitive true interpretation of the sentence “Plato did not believe that Hesperus was Phosphorus”. In response, I present a simple theory of attitude reports which employs a fine-grained semantics for names, according to which names which intuitively name the same thing may have distinct compositional semantic values. This simple theory solves the problem with the concept-generator theory, but, as (...) I go on to show, it has problems of its own. I present three examples which the concept-generator theory can accommodate, but the simple fine-grained theory cannot. These examples motivate the full theory of the paper, which combines the basic ideas behind the concept-generator theory with a fine-grained semantics for names. The examples themselves are of interest independently of my theory: two of them constrain the original concept-generator theory more tightly than previously discussed examples had. (shrink)

AbstractThis essay argues for a new interpretation of the notion of “unity” in Yangming’s 王陽明 famous doctrine of the “unity of knowledge and action” (zhi xing he yi 知行合一). I distinguish two parts of Wang’s doctrine: one concerning training (gong fu 工夫), and one concerning the “original natural condition” of knowledge and action (ben ti 本體). I focus on the latter aspect of the doctrine, and argue that Wang holds, roughly, that a person exhibits knowledge in its original natural condition (...) if and only if the person exhibits action in its original natural condition. Moreover, I argue that Wang denies that knowledge in its original natural condition is identical to action in its original natural condition. (shrink)

Are LLMs cultural technologies like photocopiers or printing presses, which transmit information but cannot create new content? A challenge for this idea, which we call bibliotechnism, is that LLMs generate novel text. We begin with a defense of bibliotechnism, showing how even novel text may inherit its meaning from original human-generated text. We then argue that bibliotechnism faces an independent challenge from examples in which LLMs generate novel reference, using new names to refer to new entities. Such examples could be (...) explained if LLMs were not cultural technologies but had beliefs, desires, and intentions. According to interpretationism in the philosophy of mind, a system has such attitudes if and only if its behavior is well explained by the hypothesis that it does. Interpretationists may hold that LLMs have attitudes, and thus have a simple solution to the novel reference problem. We emphasize, however, that interpretationism is compatible with very simple creatures having attitudes and differs sharply from views that presuppose these attitudes require onsciousness, sentience, or intelligence (topics about which we make no claims).

An opinionated introduction to philosophical issues connected to common knowledge.

According to relationism, for Alice to believe that some rabbits can speak is for Alice to stand in a relation to a further entity, some rabbits can speak. But what could this further entity possibly be? Higher-order metaphysics seems to offer a simple, natural answer. On this view (roughly put), expressions in different syntactic categories (for instance: names, predicates, sentences) in general denote entities in correspondingly different ontological categories. Alice's belief can thus be understood to relate her to a sui (...) generis entity denoted by "some rabbits can speak", belonging to a different ontological category than Alice herself. This straightforward account of the attitudes has historically been deemed so attractive that it was seen as providing an important motivation for higher-order metaphysics itself (Prior [1971]). But I argue that it is not as straightforward as it might seem, and in fact that propositional attitudes present a foundational challenge for higher-order metaphysics. (shrink)

This paper studies one aspect of the great Ming dynasty philosopher Wang Yangming’s (王陽明 1472-1529) celebrated doctrine of the unity of knowledge and action (zhi xing he yi 知行合一). Wang states that his doctrine does not apply to all knowledge, but only to an elevated form of knowledge, which he sometimes calls “genuine knowledge” (zhen zhi 真知). But what is “genuine knowledge”? I develop and compare four different interpretations of this notion: the perceptual, practical, normative and introspective models. The main (...) aim of the paper is to develop these models in more detail than has been done before. But at the end of the paper I argue that the introspective model is to be preferred over the alternatives. (shrink)

Among philosophers, Fregeanism and sententialism are widely considered two of the leading theories of the semantics of attitude reports. Among linguists, these approaches have received little recent sustained discussion. This paper aims to bridge this divide. I present a new formal implementation of Fregeanism and sententialism, with the goal of showing that these theories can be developed in sufficient detail and concreteness to be serious competitors to the theories which are more popular among semanticists. I develop a modern treatment of (...) quantifying in for Fregeanism and sententialism, in the style of Heim and Kratzer, and then show how these theories can—somewhat surprisingly—account for “third readings” on the model of the “Standard Solution” from possible-worlds semantics. The resulting Fregean/sententialist proposal has a distinctive attraction: it treats data related to counterfactual attitudes —which have proven challenging to accommodate in the setting of possible worlds semantics—straightforwardly as third readings.

This paper introduces the axiom of Negative Dominance, stating that if a lottery f is strictly preferred to a lottery g, then some outcome in the support of f is strictly preferred to some outcome in the support of g. It is shown that if preferences are incomplete on a sufficiently rich domain, then this plausible axiom, which holds for complete preferences, is incompatible with an array of otherwise plausible axioms for choice under uncertainty. In particular, in this setting, Negative (...) Dominance conflicts with the standard Independence axiom. A novel theory, which includes Negative Dominance, and rejects Independence, is developed and shown to be consistent. (shrink)

Remarks on method in the history of Chinese philosophy for analytic philosophy. (Published in a Chinese Translation.).

It was also recommended that future researchers be encouraged to conduct this kind of research in a new location and to set to expand this kind of study. (shrink)

According to the structured theory of propositions, if two sentences express the same proposition, then they have the same syntactic structure, with corresponding syntactic constituents expressing the same entities. A number of philosophers have recently focused attention on a powerful argument against this theory, based on a result by Bertrand Russell, which shows that the theory of structured propositions is inconsistent in higher order-logic. This paper explores a response to this argument, which involves restricting the scope of the claim that (...) propositions are structured, so that it does not hold for all propositions whatsoever, but only for those which are expressible using closed sentences of a given formal language. We call this restricted principle Closed Structure, and show that it is consistent in classical higher-order logic. As a schematic principle, the strength of Closed Structure is dependent on the chosen language. For its consistency to be philosophically significant, it also needs to be consistent in every extension of the language which the theorist of structured propositions is apt to accept. But, we go on to show, Closed Structure is in fact inconsistent in a very natural extension of the standard language of higher-order logic, which adds resources for plural talk of propositions. We conclude that this particular strategy of restricting the scope of the claim that propositions are structured is not a compelling response to the argument based on Russell’s result, though we note that for some applications, for instance to propositional attitudes, a restricted thesis in the vicinity may hold some promise.

The difficult phrase ὅ ποτε ὄν ἐστι (hereafter ‘OPO’), which occurs in key passages in Aristotle’s discussions of blood and of time, has long vexed interpreters of Aristotle. This paper proposes a new interpretation of OPO, which resolves some textual and interpretative problems about Aristotle’s theories of blood and of time. My interpretation will also shed light on more general issues in Aristotle’s metaphysics. In the passages I will discuss, Aristotle takes both blood and time to be examples of his (...) peculiar ‘coupled entities’. He then uses OPO to provide explanations which differ from what we might call his ‘standard’ metaphysical explanations. On the ‘standard’ approach, Aristotle explains derivative entities—non-substances—by describing their relationship to substances. By contrast to this standard form of explanation, when Aristotle uses OPO he explains blood and time by describing their relationship to non-substances. This paper thus identifies a new species of metaphysical dependence in Aristotle. In addition, it provides detailed examination of evidence concerning whether Aristotle himself used coupled entities in his own physical and metaphysical theories. (shrink)

I respond to P. J. Ivanhoe's criticisms of my translation of a key passage in Wang Yangming.

A translation of two untranslated epistolary exchanges of Wang Yangming, which provide a record of how he understood the doctrine of the unity of knowledge and action after 1521.

This article presents a new interpretation of the great Ming dynasty philosopher Wang Yangming’s celebrated doctrine of the “unity of knowledge and action”. Wang held that action was not unified with all knowledge, but only with an elevated form of knowledge, which he sometimes called “genuine knowledge”. I argue for a new interpretation of this notion, according to which genuine knowledge requires freedom from a form of doxastic conflict. I propose that, in Wang’s view, a person is free from this (...) form of doxastic conflict if and only if they are acting virtuously. (shrink)

In this paper we consider the possibility of a Quantum Molinism : such a view applies an analogue of the Molinistic account of free will‘s compatibility with God’s foreknowledge to God’s knowledge of (supposedly) indeterministic events at a quantum level.

We consider various formulations of such a Quantum Molinism, and after rejecting a number of options arrive at one (...) seemingly coherent formulation. (shrink)

An action is agentially perfect if and only if, if a person tries to perform it, they succeed, and, if a person performs it, they try to. We argue that trying itself is agentially perfect: if a person tries to try to do something, they try to do it; and, if a person tries to do something, they try to try to do it. We show how this claim sheds new light on questions about basic action, the logical structure of (...) intentional action, and the notion of "options" in decision theory. On the way to these central ideas, we argue that a person can try to do something even if they believe it is impossible that they will succeed, that a person can try to do something even if they do not want to succeed, and that a person can try to do something even if they do not intend to succeed.

Standard models in epistemic game theory make strong assumptions about agents’ knowledge of their own beliefs. Agents are typically assumed to be introspectively omniscient: if an agent believes an event with probability p, she is certain that she believes it with probability p. This paper investigates the extent to which this assumption can be relaxed while preserving some standard epistemic results. Geanakoplos (1989) claims to provide an Agreement Theorem using the “truth” axiom, together with the property of balancedness, a significant (...) relaxation of introspective omniscience. I provide an example which shows that Geanakoplos’s statement is incorrect. I then introduce a new property, local balancedness, which allows us both to correct Geanakoplos’s result, and to extend it to cases where the truth axiom may fail. I exploit this general Agreement Theorem to provide novel epistemic conditions for correlated and Nash equilibrium, both of which relax the assumption of introspective omniscience. In all three cases, the results are also extended to infinite state spaces. (This is Chapter 5 of my 2014 Oxford DPhil (PhD) thesis.). (shrink)

The sense of form that provides the modern poet with a unique experience of the literary object has been crucial to various attempts to compare poetry to other cultural activities.

And yet their poetry is more crucially concerned with the sudden emergence of visible "worlds" containing verbal objects that integrate a new kind of literary (...) text. This paper discusses the emergence of "aesthetic worlds" in the work of both poets and then examines how a common concern with Baroque form unites them in the phenomenological task of overcoming Cartesian dualism.

Since it was inspired by Bernard and developed and named by Cannon, the conceptof homeostasis has been invoked by many as the central theoretical framework for physiology. Ithas also been the target of numerous criticisms that have elicited the introduction of a plethoraof alternative concepts. We argue that many of the criticisms actually target the more restrictiveaccount of homeostasis advanced by the cyberneticists. What was crucial to Bernard and Cannonwas a focus on the maintenance of the organism as the goal (...) of physiological regulation. We analysehow Bernard’s and Cannon’s broad conception of what was required to maintain the organismwas narrowed to negative feedback, characterized in terms of setpoints, by the cyberneticistsand demonstrate how many of the alternative concepts challenge the role of setpoints – treatingthem as variable in light of circumstances or in anticipation of future circumstances, or asdispensable altogether. To support our analysis, we draw on the experimental and theoreticalwork on thermoregulation, a phenomenon that has been considered as a paradigmatic example ofhomeostasis and has been a common focus of those advancing alternative concepts. To integratethe insights advanced by the original proponents of homeostasis and the theorists proposingreplacement notions we advance a framework in which regulation is viewed from the perspectiveof maintaining the organism.

Kit Fine’s logic of essence and his reduction of modality crucially rely on a principle called the ‘monotonicity of essence’. This principle says that for all pluralities, xx and yy, if some xx belong to some yy, then if it is essential to xx that p, it is also essential to yy that p. I argue that on the constitutive notion of essence, this principle is false. In particular, I show that this principle is false because it says that some (...) propositions are essential to yy even though those propositions are only about some of its members. I then consider modifications to the principle appealing to consequential essence and argue that such a modification is inconsistent with a central. (shrink)

Gerald Gaus argued in his 1996 book Justificatory Liberalism that proponents of public reason liberalism should attempt to ground their position in a specific epistemology. Critics of public reason liberalism such as David Enoch have also argued that public reason liberals need to elucidate their epistemic claims. Surprisingly, few public reason liberals have taken up Gaus and Enoch on their challenge. This paper will interact with the epistemological position undergirding the public justification principle, access internalism, arguing that it fails. In (...) its place, I put forward and defend proper functionalism as the better grounding epistemology, and then defend the new theory from possible objections. The result will be a synthesis of Nicholas Wolterstorff’s version of liberalism and an externalist version of convergence public reason liberalism. (shrink)

We provide a general argument against value incomparability, based on a new style of impossibility result. In particular, we show that, against plausible background assumptions, value incomparability creates an incompatibility between two very plausible principles for ranking lotteries: a weak "negative dominance" principle (to the effect that Lottery 1 can be better than Lottery 2 only if some possible outcome of Lottery 1 is better than some possible outcome of Lottery 2) and a weak form of ex ante Pareto (to (...) the effect that, if Lottery 1 gives an unambiguously better prospect to some individuals than Lottery 2, and equally good prospects to everyone else, then Lottery 1 is better than Lottery 2). After spelling out our results, and the arguments based on them, we consider which principle the proponent of incomparability ought to reject. (shrink)

This paper deals with what a government funded development agency should do when a developing country imposes restrictions on the development process which discriminate on the basis of gender against some members of the development agency’s staff. The conclusion is that there are circumstances in which development agencies should continue their work in the face of gender discrimination but they should not instigate development projects if doing so would involve them in gender discrimination. A set of procedures for a development (...) agency to follow in these difficult circumstances is outlined. It is argued that an agency is entitled to violate a moral principle when so doing will reduce violations of that same principle. (shrink)

In their Why Machines Will Never Rule the World, Landgrebe and Smith (2023) argue that it is impossible for artificial general intelligence (AGI) to succeed, on the grounds that it is impossible to perfectly model or emulate the “complex” “human neurocognitive system”. However, they do not show that it is logically impossible; they only show that it is practically impossible using current mathematical techniques. Nor do they prove that there could not be any other kinds of theories than those in (...) current use. Even if perfect theories were impossible or unlikely, perfection may not be needed and may even be unhelpful. (shrink)

Several theorists have observed that attitude reports have what we call “revisionist” uses. For example, even if Pete has never met Ann and has no idea that she exists, Jane can still say to Jim ‘Pete believes Ann can learn to play tennis in ten lessons’ if Pete believes all 6-year-olds can learn to play tennis in ten lessons and it is part of Jane and Jim’s background knowledge that Ann is a 6-year-old. Jane’s assertion seems acceptable because the claim (...) she reports Pete as believing is entailed by Pete’s beliefs if they are revised in light of Jane and Jim’s background knowledge. We provide a semantic theory of revisionist reports based on this idea. We observe that the admissible “revisions” are limited in a striking way. Jane cannot say ‘Pete thinks Ann is a 6-year-old and can play tennis in ten lessons’ in the same context that she can say ‘Pete believes Ann can learn to play tennis ten lessons’, even though this too follows from Jane and Jim’s background knowledge together with what Pete believes. Our theory predicts the infelicity of these latter reports. It also has the resources to predict the truth of “exported” attitude reports and casts the relationship between these reports and “singular thought” in a new light. We conclude by discussing how revisionist reports make trouble for a simplistic view of the connection between the relations expressed by attitude verbs in natural language and the relations of most interest to philosophers of mind and cognitive science.

The disjunction problem and the distality problem each presents a challenge that any theory of mental content must address. Here we consider their bearing on purely probabilistic causal theories. In addition to considering these problems separately, we consider a third challenge—that a theory must solve both. We call this “the hard problem.” We consider 8 basic ppc theories along with 240 hybrids of them, and show that some can handle the disjunction problem and some can handle the distality problem, but (...) none can handle the hard problem. This is our main result. We then discuss three possible responses to that result, and argue that though the first two fail, the third has some promise. (shrink)

There are two distinct approaches to Bayesian modelling in cognitive science. Black-box approaches use Bayesian theory to model the relationship between the inputs and outputs of a cognitive system without reference to the mediating causal processes; while mechanistic approaches make claims about the neural mechanisms which generate the outputs from the inputs. This paper concerns the relationship between these two approaches. We argue that the dominant trend in the philosophical literature, which characterizes the relationship between black-box and mechanistic approaches to (...) Bayesian cognitive science in terms of the dichotomy between instrumentalism and realism, is misguided. We propose that the two distinctions are orthogonal: black-box and mechanistic approaches to Bayesian modelling can each be given either an instrumentalist or a realist interpretation. We argue that the current tendency to conflate black-box approaches with instrumentalism and mechanistic approaches with realism stems from unwarranted assumptions about the nature of scientific explanation, the ontological commitments of scientific theories, and the role of abstraction and idealization in scientific models. We challenge each of these assumptions to reframe the debates over Bayesian modelling in cognitive science. (shrink)

According to a rights forfeiture theory of punishment, liability to punishment hinges upon the notion that criminals forfeit their rights against hard treatment. In this paper, I assume the success of rights forfeiture theory in establishing the permissibility of punishment but aim to develop the view by considering how forfeited rights might be reclaimed. Built into the very notion of proportionate punishment is the idea that forfeited rights can be recovered. The interesting question is whether punishment is the sole means (...) for reclaiming forfeited rights. I argue for a pluralistic theory of rights reclamation, according to which, there are multiple ways by which a wrongdoer can recapture her forfeited rights. In particular, I argue that offering remorseful compensation is a valid means by which a wrongdoer might partially, or fully, reclaim her right against punishment. (shrink)
