Kant claims that we cannot cognize the mutual interaction of substances without their being in space; he also claims that we cannot cognize a ‘spatial community’ among substances without their being in mutual interaction. I situate these theses in their historical context and consider Kant’s reasons for accepting them. I argue that they rest on commitments regarding the metaphysical grounding of, first, the possibility of mutual interaction among substances-as-appearances and, second, the actuality of specific distance-relations among such substances. By illuminating these commitments, I shed light on Kant’s metaphysics of space and its relation to Newton and Leibniz’s views.

In ‘Kripke on epistemic and metaphysical possibility: two routes to the necessary a posteriori’, Scott Soames identifies two arguments for the existence of necessary a posteriori truths in Naming and Necessity (NN). He argues that Kripke’s second argument relies on either of two principles, each of which leads to contradiction. He also claims that it has led to ‘two-dimensionalist’ approaches to the necessary a posteriori which are fundamentally at odds with the insights about meaning and modality expressed in NN. I argue that the alleged second argument is not in NN. I identify the mistakes that lead to Soames’ misinterpretation.

According to the guise of the good thesis, we desire things under the ‘guise of the good.’ Here I sympathetically articulate a generic formulation of the guise of the good thesis, and address a problem for the view, which I call the problem of partiality. The problem is, roughly, that our partial pro-attitudes–for example, our special concern for ourselves–do not correspond to what is absolutely good. I criticize three solutions to the problem, and propose an alternative strategy, on which partial pro-attitudes constitute a species of illusion.

Many accounts of the morality of abortion assume that early fetuses must all have or lack moral status in virtue of developmental features that they share. Our actual attitudes toward early fetuses don’t reflect this all-or-nothing assumption. If we start with the assumption that our attitudes toward fetuses are accurately tracking their value, then we need an account of fetal moral status that can explain why it is appropriate to love some fetuses but not others. I argue that a fetus can come to have moral claims on persons who have taken up the activity of person-creation.

This paper offers a new interpretation of the young Spinoza’s method of distinguishing the true ideas from the false, which shows that his answer to the sceptic is not a failure. This method combines analysis and synthesis as follows: if we can say of the object of an idea (a) which simple things underlie it, (b) how it can be constructed out of simple elements, and (c) what properties it has after it has been produced, doubt concerning the object simply makes no sense. The paper also suggests a way in which this methodology connects to the ontology of the Ethics.

According to a ‘Straight’ reading of Elizabeth Anscombe’s (1975) ‘The First Person’, she holds a radically non-referring view of ‘I’. Specifically, ‘I’ is analogous to the expletive ‘it’ in ‘It’s raining’. I argue that this is not her conclusion. Her substantive view, rather is that if what you mean by ‘reference’ is a certain rich and recherché notion tracing to Frege, then ‘I’ is not a referring term. Her methodological point is that one shouldn’t be ‘bewitched by language’ into thinking that ‘I’, because of its syntax, must exhibit ‘reference’ in this sense.

Social networking services provide services in return for rights to commercialize users’ personal data. We argue that what makes this transaction permissible is not users’ autonomous consent but the provision of sufficiently valuable opportunities to exchange data for services. We argue that the value of these opportunities should be assessed for both (a) a range of users with different decision-making abilities and (b) third parties. We conclude that regulation should shift from aiming to ensure autonomous consent towards ensuring that users face options that they will use to advance individual and common interests.

According to conventional wisdom, the causes of economic inequality under capitalism are different in kind from those operating in a socialist system. In socialist societies today the distribution of wealth and income is determined by political authority, whereas in capitalism it is thought to arise mainly from the choices of individuals freely transferring goods and services in the competitive market. Robert Nozick's account of the workings of a ‘free society’ expresses this view clearly:

Contractarians view justice (or, more ambitiously, all of morality) as being defined by a contract made by rational individuals. No one supposes that this contract is actual, and the fact that it is merely hypothetical raises a number of questions both about the assumptions under which it would be actual and about the force of hypothetical agreement that is contingent on these assumptions.

Particular contractarian theories must specify the circumstances of the agreement and the endowments, beliefs, desires, and degree and type of rationality of the agents. How these issues are settled determines the force of the hypothetical agreement. The fact that ignorant people who desired only universal suffering would, under duress, agree to a certain principle gives us no reason to believe the principle is a correct moral principle or to think it rational to accept or act on it: some counterfactual assumptions undermine entirely the moral force of hypothetical agreement. On the other hand, to take people just as they are, with their current beliefs, desires, endowments, and all, is to endorse their ignorance and mistakes as well as any previous injustice that affects their bargaining power.

Recent moral philosophy has been characterized by some serious attempts to show that both Kantian and utilitarian moralities leave us with insufficient room to pursue our personal projects and relationships. These moralities have been charged with demanding a kind of impartiality that leaves us with too little space for developing ourselves and our friendships, family relations, communities, and nations in the ways best suited for us. Critics claim these theories implausibly maintain that if our personal relationships and affinities do not further the ends of moral duty or maximum utility, they are of no value and hence we lack reason to devote ourselves to them. In what follows, I will assume that a conception of morality would indeed be implausible if it were to demand impartiality in the strong sense that it would be impermissible to favor our own projects and ambitions, to care especially about the welfare of certain persons rather than others, and sometimes to give preference to those we care most about, even when we could benefit strangers more.

If by the term ‘matter’ is meant the extended, movable, and corporeal stuff out of which perceptible objects are made, then, according to one interpretative tradition, there is nothing in Aristotle's account of the world that corresponds to matter in the above sense of physical stuff. Aristotle does indeed describe certain things as extended, movable, and corporeal: for example, the five elements, earth, water, air, fire, and ether, as well as everything made out of them. He also has the concept of a material cause, that is, the raw materials out of which something can be made or generated, and he makes frequent use of this concept in his analysis of perceptible substances. Still, the fact that Aristotle thought about what perceptible substances are made of is insufficient evidence for attributing to him the concept of matter as physical stuff. In addition, we would want to know whether he thought that all perceptible substances are extended, movable, and corporeal precisely because they are made out of matter, and whether any aspect of their behavior is to be explained simply by virtue of their nature as material objects.

In his book The Rediscovery of the Mind (hereafter RM), John Searle attacks computational psychology with a number of new and boldly provocative claims. Specifically, in the penultimate chapter entitled ‘The Critique of Cognitive Reason,’ Searle targets what he calls ‘cognitivism,’ according to which our brains are digital computers that process a mental syntax. And Searle denies this view on grounds that the attribution of syntax is observer relative. A syntactic property is arbitrarily assigned to a physical system, he thinks, with the result that syntactic states ‘do not even exist except in the eyes of the beholder’ (RM, 215). This unabashed anti-realism differs significantly from Searle's earlier work. The Chinese room argument, for example, was intended to show that syntactic properties will not suffice for semantics, where the syntax was realistically construed. But now Searle claims that physical properties will not suffice to determine a system's syntactic properties.

This paper is designed to reinterpret and clarify John Stuart Mill's ideas on science. Past discussions of these ideas strike me as unsatisfactory in two crucial respects. In the first place they have encouraged us to regard Mill's principal work on epistemology, A System of Logic, as fundamentally inductivist This is the received interpretation of Mill's Logic and one finds it summarized and affirmed in the remark of Laurens Laudan that 'by and large' Mill was 'a rather orthodox inductivist who saw science as the generalisation of observation and who argued that all scientific ideas (including those of mathematics) come directly from experience.

It is technically possible to clone a human being. The result of the procedure would be a human being in its own right. Given the current level of cloning technology concerning other animals there is every reason to believe that early human clones will have shorter-than-average life-spans, and will be unusually prone to disease. In addition, they would be unusually at risk of genetic defects, though they would still, probably, have lives worth living. But with experimentation and experience, seriously unequal prospects between cloned and noncloned people should erode. We shall ignore arguments about cloning that focus on the potential for harm to the fetus or resultant human being, where harm is understood solely in terms of physical and mental health. Unless the resultant people would generally have lives worth living there is no positive case for cloning, or any other form of reproduction, for that matter. If the resultant beings will generally have lives worth living there is a prima facie case for allowing cloning. We imagine the case in which the resultant beings will have lives well worth living.

It was common enough in the seventeenth and eighteenth centuries to find philosophers holding the position that for something to be ‘in the mind’ and for that mind to be conscious of it are one and the same thing. The thought is that consciousness is a relation between a mind and a mental entity playing the same role as the relation of inherence found between a substance and qualities belonging to it. What it is, on this view, for something to ‘inhere’ in the mind is for that mind to be conscious of it. Locke was explicit in his acceptance of such a claim, writing, for instance,

Introduction

It is at least a bit embarrassing, perhaps even scandalous, that debate should still rage over the sheer existence of qualia, but they continue to find able defenders after decades of being attacked as relics of ghostly substances, epiphenomenal non-entities, nomological danglers and the like; the intensity of the current confrontation is captured vividly by Daniel Dennett:

On many accounts, the criterion of our diachronic identity or persistence consists in or comprises some psychological conditions. As on Locke's account, these conditions often include one's appealing to the relation of remembering having an experience of. Contemporary theorists are unlikely to claim simply that a necessary condition for Pm at tm being the same person as Pn at a later time, tn, is that Pn remembers having experiences had by Pm at tm. They are more likely to appeal, as does Derek Parfit, to a ‘continuity of memory’ or ‘overlapping chains’ of memories, that is, to assert that Pn must at least remember having experiences had by somebody, Pn-1, existing at some time in-between tm and tn, that Pn-1 in turn must remember having experiences had by somebody Pn-2 … and so on back to Pm.
