Locke notoriously included number amongst the primary qualities of bodies and was roundly criticized for doing so by Berkeley. Frege echoed some of Berkeley's criticisms in attacking the idea that ‘Number is a property of external things’, while defending his own view that number is a property of concepts. In the present paper, Locke's view is defended against the objections of Berkeley and Frege, and Frege's alternative view of number is criticized. More precisely, it is argued that numbers are assignable to pluralities of individuals. However, it is also argued that Locke went too far in asserting that ‘Number applies itself to ... everything that either doth exist, or can be imagined’.

In a paper entitled ‘Saints and Heroes’1 Professor J. O. Urmson has criticised ‘the trichotomy of duties, indifferent actions, and wrongdoing’ (p. 215), commonly found in moral philosophy, on the ground that it fails to cover an important class of actions, of which saintly and heroic actions are ‘conspicuous” but by no means the only examples. I am inclined to think that this trichotomy is defensible, and that at least it deserves a much longer run for its money than Urmson gives it. The form in which he presents it, however, makes it more implausible than it need be and this is perhaps the main reason why he finds it so indefensible.

An almost unbelievable amount of false philosophy has arisen through not realizing what ‘existence’ means…. [It] rests upon the notion that existence is, so to speak, a property that you can attribute to things, and that the things that exist have the property of existence and the things that do not exist do not. That is rubbish (Bertrand Russell).

I have dared to puncture several metaphysical balloons and nothing came out of them but hot air (Voltaire).

The concept of rights is among the more thoroughly examined in political philosophy. Nonetheless, it remains ontologically elusive and morally problematical. In the form of an allegedly natural endowment bequeathed by the Stoic philosophers, it was famously dismissed by Bentham as ‘nonsense on stilts’. Chiefly by way of natural law theory and versions of Kantian moral philosophy rights arise at once from the presupposed autonomy of rational beings and from certain duties others have to beings of such a kind. Within this tradition it is argued that morality itself is grounded in the autonomy of rational beings and that whatever overrides this autonomy converts such beings to instrumental means. Accordingly, there is a basic right to be regarded as a moral being and it is this right that generates or is foundational for the rest. Debate continues, of course, on such questions as to whether autonomy per se either logically or morally requires dutiful respect and whether rationality per se is either a necessary or a sufficient condition for autonomy itself.

This paper defends a substance-based metaphysics for organisms against three arguments for thinking that we should replace a substantial understanding of living things with a processual one, which are offered by Dan Nicholson and John Dupré in their edited collection, Everything Flows: Towards a Processual Philosophy of Biology (Oxford: Oxford University Press, 2018). Dupré and Nicholson consider three main empirical motivations for the adoption of a process ontology in biology. These motivations are alleged to stem from facts concerning (i) metabolism; (ii) the life cycles of organisms; and (iii) ecological interdependence. The paper discusses each of the three arguments in turn and concludes that none gives us any compelling reason to abandon the metaphysics of things. At best, they are arguments against a kind of caricature substance metaphysics that ought never to have been in the running in any case. Then, at the end of the paper, it is suggested that there may be more positive arguments for insisting on retaining things in our metaphysics, arguments which, perhaps ironically (given the opposed standpoint of Everything Flows) get their main impetus from the phenomenon of life.

The paper argues that Hume's philosophy is best described as sceptical materialism. It is argued that the conjunction is not self-contradictory as long as ‘scepticism’ is understood in its ancient sense, as the denial of knowledge of the essences of things. It is further argued that scepticism (thus understood) and materialism are natural bedfellows, since a thoroughgoing materialism denies any special status to human rational powers. The content of the Treatise of Human Nature is then shown to conform to this understanding: the Treatise consistently employs an implicitly materialist faculty psychology in order to arrive at its sceptical standpoint. Finally, it is shown that Hume's philosophy can be understood to be a sceptical rewriting of the dogmatic materialism of Hobbes.

We falter and stammer when trying to describe our own mental acts. Many mental acts, including thinking, are what the author calls ‘chain-undertakings’, that is, courses of action with some over-arching purpose governing the moment-by-moment sub-acts of which we are introspectively aware. Hence the intermittency and sporadicness of the passage of mental activity which constitutes thinking about something.

Certain primitive Yoruba carry about with them boxes covered with cowrie shells, which they treat with special regard. When asked what they are doing, they apparently reply that the boxes are their heads or souls and that they are protecting them against witchcraft. Is that an interesting fact or a bad translation? The question is, I believe, partly philosophical. In what follows, I shall propound and try to solve the philosopher's question, arguing that it has large implications for the theory of Social Anthropology.

This theory regards intentions as mental states, e.g., attitudes, which, typically, have causal power. But we do not speak of our intentions as having such powers. Instead, we speak of a person's resolve, determination, or his anxiety, eagerness, and so forth, as the ‘powers’ that move us. Of course, one desires for various reasons to carry out his various intentions but that desire is not a component of the intentions. An intention is, roughly, the course of action that one has adopted, so it has no such components.

There are other characteristics of intentions which the mental state idea of intentions does not share. Intentions do not have the temporal characteristics that mental states have, or share the curious context dependency that intentions have. And since, according to the theory, mental states operate causally, it would not be possible for a person to commit himself to a course of action as we ordinarily do when we make a promise or sign an agreement or contract.

Wittgenstein's later philosophy and the doctrines of Mahayana Buddhism integral to Zen coincide in a fundamental aspect: for Wittgenstein language has, one might say, a mystical base; and this base is exactly the Buddhist ideal of acting with a mind empty of thought. My aim is to establish and explore this phenomenon. The result should be both a deeper understanding of Wittgenstein and the removal of a philosophical objection to Zen that has troubled some people.

In his well known proposition that pleasures differ qualitatively, Mill seems to be arguing three principal points. (1) ‘Mental’ pleasures as a kind are intrinsically ‘more desirable and more valuable’ than ‘bodily pleasures’ (p. 12). (2) This estimation of pleasure, Mill says, is such as to rule out the claim that it ‘should be supposed to depend on quantity alone.’ Indeed, he continued, the ‘superiority in quality’ might be ‘so far outweighing quantity as to render it, in comparison, of small account’ (p. 12). (3) The ‘test of quality and the rule for measuring it against quantity,’ Mill says, is ‘the preference’ of experienced judges (p. 16). ‘[T]he judgment of those who are qualified by knowledge of both, or, if they differ, that of the majority among them, must be admitted as final’ (p. 15).

The concept of ideology plays an important part in contemporary social and political thinking. In many works which raise the question about the relationship between what men think and how their societies operate some mention of ideology is made. Since the variety of thinkers who write about this relationship have a variety of views on the subject, it is not at all surprising that they disagree about just what an ideology is. It might be helpful if we could agree on just one usage, or, failing that, understand why a variety of usages is necessary and understand them.

This article aims to review the standard objections to dualism and to argue that either they will fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are selected. The remaining sections are analyses of the standard objections to substance dualism: It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful.

Freud is often assumed to have given an explanation of how human beings acquire a morality, especially as it is manifested in the phenomenon of moral conscience. Freud himself certainly lends credence to such an interpretation of his theory, as the following passage testifies.

A moral compromise is a compromise on moral matters; it is agreement in the face of moral disagreement but where there is agreement on the importance of consensus – namely that it secures a morally desirable outcome. It is distinguishable from other forms of agreement, and an important distinction between moral compromise with public agreement and moral compromise with public disagreement is also made. Circumstances in which the former might be permissible are outlined, and the sense in which it is allowed all things considered to agree is made clear. The relevant discussions of Dan Brock and Mary Warnock on the role of the philosopher to public policy are critically reviewed. Finally, a brief list is offered of the considerations relevant to an estimation of whether and, if so, when such compromise is allowed.

This is a paper about philosophical methodology or, better, methodologies. Most of the material that has been published to date under the rubric of African philosophy has been methodological in character. One reason for this is the conflicts that sometimes arise when philosophers in Africa attempt to reconcile their relationships with both academic philosophy and so-called African '‘traditional’ systems of thought. A further complication is that the studies of traditional African thought systems that become involved in these conflicts are themselves products of academia– of disciplinary methodologies.

The object of this essay is to discuss Ludwig Wittgenstein's remarks in Philosophical Investigations and elsewhere in the posthumously published writings concerning the role of therapy in relation to philosophy. Wittgenstein's reflections seem to suggest that there is a kind of philosophy or mode of investigation targeting the philosophical grammar of language uses that gratuitously give rise to philosophical problems, and produce in many thinkers philosophical anxieties for which the proper therapy is intended to offer relief. Two possible objectives of later Wittgensteinian therapy are proposed, for subjective psychological versus objective semantic symptoms of ailments that a therapy might address for the sake of relieving philosophical anxieties. The psychological in its most plausible form is rejected, leaving only the semantic. Semantic therapy in the sense defined and developed is more general and long-lasting, and more in the spirit of Wittgenstein's project on a variety of levels. A semantic approach treats language rather than the thinking, language-using subject as the patient needing therapy, and directs its attention to the treatment of problems in language and the conceptual framework a language game use expresses in its philosophical grammar, rather than to soothing unhappy or socially ill-adjusted individual psychologies.

‘Marital faithfulness’ refers to faithful love for a spouse or lover to whom one is committed, rather than the narrower idea of sexual fidelity. The distinction is clearly marked in traditional wedding vows. A commitment to love faithfully is central: ‘to have and to hold from this day forward, for better for worse, for richer for poorer, in sickness and in health, to love and to cherish, till death us do part… and thereto I plight [pledge] thee my troth [faithfulness]’. Sexual fidelity is promised in a subordinate clause, symbolizing its supportive role in promoting love's constancy: ‘and, forsaking all other, keep thee only unto her/him.’
