Ferrajoli’s Argument for Structural Entrenchment

This paper engages with Ferrajoli’s contribution to the philosophical debate on constitutional democracy and in particular his conception of ‘structural entrenchment’, or the basis upon which one can defend the normativity of the Constitution as ‘higher law’, which can trump or limit legislation, without infringing democratic principles. Ferrajoli’s own understanding of ‘structural entrenchment’ is compared to Rawls’s and Dworkin’s arguments in support of it. Ferrajoli’s position is neither grounded on a philosophy of history, as in Rawls, nor on a version of moral realism, as for Dworkin, but on a formal understanding of the nature of fundamental rights, and in a conception of democratic sovereignty as ‘joint ownership.’     

On the Argument for Jian’ai

In all three versions of the “Jian’ai” 兼愛 Chapter in the Mozi 墨子, variations of a central argument may be found. This argument proceeds by advancing a diagnosis for what causes the various evils that beset the world, and it is on this basis that the Mohists propose jian’ai as the solution. The study examines this main argument in some detail, with the aim of improving both our understanding of the Mohist ethical doctrine and also our appreciation of their argumentative practices. The study shows that distinct ethical injunctions of varying degrees of stringency can be derived from the argument, though they all embody an underlying notion of impartiality. This impartiality—while in many ways recognizably attractive to us—puts Mohist jian’ai in tension with certain notions regarding the ethical significance of special relations. In addition, the paper argues that the Mohists main argument for jian’ai contains a critical flaw.     

Newton’s Conceptual Argument for Absolute Space

While many take Newton’s argument for absolute space to be an inference to the best explanation, some argue that Newton is primarily concerned with the proper definition of true motion, rather than with independent existence of spatial points. To an extent the latter interpretation is correct. However, all prior interpretations are mistaken in thinking that ‘absolute motion’ is defined as motion with respect to absolute space. Newton is also using this notion to refer to the quantity of motion (momentum). This reading reveals a misunderstood argument for absolute space, according to which absolute space is necessary for a workable definition of momentum.     

Discussions Quinton’s Neglected Argument for Scientific Realism

Summary  This paper discusses an argument for scientific realism put forward by Anthony Quinton in The Nature of Things. The argument – here called the controlled continuity argument – seems to have received no attention in the literature, apparently because it may easily be mistaken for a better-known argument, Grover Maxwell’s “argument from the continuum”. It is argued here that, in point of fact, the two are quite distinct and that Quinton’s argument has several advantages over Maxwell’s. The controlled continuity argument is also compared to Ian Hacking’s “argument from coincidence”. It is pointed out that both arguments are to a large extent independent from considerations about high-level scientific theories, and that both are abductive arguments at the core. But these similarities do not dilute an important difference related to the fact that Quinton’s argument cleverly seeks to anchor belief in unobservable entities in realism about ordinary objects, which is a position shared by most contemporary scientific anti-realists.     

Against Animal Liberation? Peter Singer and His Critics

This article explores Peter Singer’s Animal Liberation thesis and examines the arguments against his work, particularly from certain moral philosophers in the late 1970s and 1980s who seriously engaged with his ideas. This article argues that due to the straightforward, minimalist nature of Singer’s preference utilitarianism, his arguments have remained highly defensible and persuasive. By advancing sentience, above characteristics like intelligence or rationality, as a sufficient criterion for possessing interests, Singer provides a justifiable principle for morally considering animal interests equal to those of humans. Numerous moral philosophers have challenged Singer, but they have struggled to seriously counter his core principle and to resolve the argument of ‘marginal cases’—that is, why do infants and intellectually disabled humans have moral status and animals do not. Ultimately, Singer broadly challenged prevailing anthropocentric views of animals and, in some instances, persuaded some of his most intransigent opponents.     

Muller’s Critique of the Argument for Aim-Oriented Empiricism

For over 30 years I have argued that we need to construe science as accepting a metaphysical proposition concerning the comprehensibility of the universe. In a recent paper, Fred Muller criticizes this argument, and its implication that Bas van Fraassen’s constructive empiricism is untenable. In the present paper I argue that Muller’s criticisms are not valid. The issue is of some importance, for my argument that science accepts a metaphysical proposition is the first step in a broader argument intended to demonstrate that we need to bring about a revolution in science, and ultimately in academic inquiry as a whole so that the basic aim becomes wisdom and not just knowledge.     

Korsgaard’s Other Argument for Interpersonal Morality: the Argument from the Sufficiency of Agency

Christine Korsgaard’s (1996, 2009) argument for the claim that one should not only value one’s own humanity but also the humanity of all other persons, ‘the publicity of reasons argument’, has been heavily criticized and I believe rightly so. However, both in an early paper (1986) and in her most recent work (forthcoming), Korsgaard does not rely on controversial, Wittgensteinian ideas regarding the publicity of reasons, but instead she uses a different argument to justify interpersonal morality, which I will refer to as ‘the argument from the sufficiency of agency’. The goal of this paper is to evaluate whether the argument from the sufficiency of agency can succeed where the publicity of reasons argument fails. I will argue that although the argument from the sufficiency of agency is potentially more promising, it fails to justify a categorical and universal principle of interpersonal morality. I argue, however, that this failure has less to do with the argument from the sufficiency of agency itself and more with Korsgaard’s specific version of it. This leaves open the possibility that other Kantian constructivist arguments from the sufficiency of agency might be more successful.     

On Defining ‘Argument’

There is no concept more central to logic and critical thinking than the concept of an argument. I here address the definition of ‘argument’ in the logical sense of the term and defend the claim that many current proposals, once they are interpreted in a way that makes them sufficiently precise, are extensionally inadequate. Definitions found in some contemporary, prominent critical thinking textbooks will serve as a springboard. I claim that each may be interpreted in an absolutist way (i.e., as providing a definition of ‘argument’ simpliciter) or a relativistic way (as providing a definition of ‘argument-for-S’, where S is some agent or group of agents), yet all turn out to be objectionable no matter which route is taken. I finish with a proposal on which the definition of ‘argument’ is an absolutist one, yet one that avoids the problems discussed for the earlier proposals.     

Understanding (in) Newton’s Argument for Universal Gravitation

In this essay, I attempt to assess Henk de Regt and Dennis Dieks recent pragmatic and contextual account of scientific understanding on the basis of an important historical case-study: understanding in Newton’s theory of universal gravitation and Huygens’ reception of universal gravitation. It will be shown that de Regt and Dieks’ Criterion for the Intelligibility of a Theory (CIT), which stipulates that the appropriate combination of scientists’ skills and intelligibility-enhancing theoretical virtues is a condition for scientific understanding, is too strong. On the basis of this case-study, it will be shown that scientists can understand each others’ positions qualitatively and quantitatively, despite their endorsement of different worldviews and despite their convictions as what counts as a proper explanation.     

The Tense Logic for Master Argument in Prior’s Reconstruction

In this paper we examine Prior’s reconstruction of Master Argument [4] in some modal-tense logic. This logic consists of a purely tense part and Diodorean definitions of modal alethic operators. Next we study this tense logic in the pure tense language. It is the logic K _t 4 plus a new axiom (P): ‘p Λ G p ⊃ P G p’. This formula was used by Prior in his original analysis of Master Argument. (P) is usually added as an extra axiom to an axiomatization of the logic of linear time. In that case the set of moments is a total order and must be left-discrete without the least moment. However, the logic of Master Argument does not require linear time. We show what properties of the set of moments are exactly forced by (P) in the reconstruction of Prior. We make also some philosophical remarks on the analyzed reconstruction. Presented by Jacek Malinowski     

Louis de La Forge and the ‘Non-Transfer Argument’ for Occasionalism

In this paper, I investigate Louis de La Forge's argument against body–body causation. His general strategy exploits the impossibility of bodies communicating their movement by transfer of motion. I call this the ‘non-transfer’ argument (NT). NT allows La Forge both to reinterpret continuous creation in an occasionalistic fashion and to support his non-occasionalistic view concerning mind–body union. First, I present how NT emerges in Descartes’ own texts. Second, I show how La Forge recasts it to draw an occasionalistic account of body–body interactions, and I discuss how La Forge supports NT with continuous creation. Third, I conclude by suggesting that this further step of his argument does not undermine his non-occasionalistic account of mind–body union.     

A New Argument for Pragmatism?

Shah, N. The Philosophical Quarterly, 56, 481–498 (2006) has defended evidentialism on the premise that only it (and not pragmatism) is consistent with both (a) the deliberative constraint on reasons and (b) the transparency feature of belief. I show, however, that the deliberative constraint on reasons is also problematic for evidentialism. I also suggest a way for pragmatism to be construed so as to make it consistent with both (a) and (b) and argue that a similar move is not available to the evidentialist. Thus, far from settling the debate in favour of evidentialism, considerations concerning the deliberative constraint on reasons support pragmatism.     

Rethinking Gibbard’s Riverboat Argument

According to the Principle of Conditional Non-Contradiction (CNC), conditionals of the form “If p, q” and “If p, not q” cannot both be true, unless p is inconsistent. This principle is widely regarded as an adequacy constraint on any semantics that attributes truth conditions to conditionals. Gibbard has presented an example of a pair of conditionals that, in the context he describes, appear to violate CNC. He concluded from this that conditionals lack truth conditions. We argue that this conclusion is rash by proposing a new diagnosis of what is going on in Gibbard’s argument. We also provide empirical evidence in support of our proposal.     

On Quine’s Translation Argument

Quine's translation argumnent figures centrally in his views on logic. The goal of this paper is to get clear on that argument. It can be interpreted as an argument to the effect that one should never translate somebody’s speech as going against a law of the translator’s logic. Key to this reading of the translation argument is the premise that one should never translate somebody's speech such that their speech is unintelligible. Ultimately, it is my aim to reject this reading. I argue that only a weaker conclusion—one that says “not most of the time” instead of the stronger “never”—should be attributed to Quine. Accordingly, I propose and defend a weaker version of the first premise that better coheres with the weaker conclusion of the translation argument. Instead of the claim that one should never translate somebody’s speech such that their speech is unintelligible I argue that we should only ascribe to Quine the claim that one should not most of the time translate somebody’s speech in a way that makes it unintelligible. I go on to  sum up the results of my discussion and respond to a criticism of my reading.

     

A New Argument for Evidentialism?

In his “A new argument for evidentialism” (Shah, Philos Q 56(225): 481–498, 2006), Nishi Shah argues that the best explanation of a feature of deliberation whether to believe that p which he calls transparency entails that only evidence can be reason to believe that p. I show that his argument fails because a crucial lemma that his argument appeals to cannot be supported without assuming evidentialism to be true in the first place.     

On Behalf of J. S. Mill's ‘Assumption of Infallibility’ Argument

According to the Cambridge Platonist Henry More, individual ‘spirits’ – the souls of humans and non-human animals – are extended but cannot be physically divided. His contemporaries and recent commentators have charged that More has never given an explication of the grounds on which the indivisibility of spirits is based. In this article, I suggest that exploring the usage that More makes of the analogy between spirits and light could go some way towards providing such an explication. More compares the relation between spirit and matter to the relation that, according to Aristotelian theories of light, holds between ‘intentional species’ and matter. I will argue that the purpose of his comparison is to highlight that both intentional species and spirits are existentially independent from matter. The existential independence of intentional species from matter expresses itself in the fact that light is not moved through the motion of the illuminated body. The existential independence of spirits from matter expresses itself in the fact that when a body that is coextensive with a spirit is divided, the spirit is not thereby divided but rather contracts into the remaining living organism.
