How math helps us solve the universe's deepest mysteries You must be able to test any physical theory in the real world. To most physicists, this is obvious. But since the 1980s, experimental physics has yielded vanishingly little insight into the fundamental physics of the universe. Meanwhile, some physicists have begun to probe the universe not with proton beams, but with pure math. They're less concerned with testable theories than with the drive to explain nature with mathematical beauty. This approach (...) is often pilloried by traditional scientists, who point out that such approaches have yet to make a correct prediction about the real world. But in The Universe Speaks in Numbers, Graham Farmelo offers a gripping tour of the history of math-based physics and explores why it may be the key to the next big breakthrough in our understanding of the nature of reality.

Do perceptual states necessarily constitute evidence epistemically supporting corresponding perceptual beliefs? Susanna Schellenberg thinks so. She argues that perceptual states, veridical or not, necessarily provide (or constitute) a kind of evidence (for the existence of the truth-maker) supporting corresponding perceptual beliefs. She uses “phenomenal evidence” as a label for this kind of evidence and calls her argument “The Phenomenal Evidence Argument.” Having introduced her project, we offer a reconstruction of Schellenberg’s argument. A key premise has it that, necessarily, for items (...) with a function, fulfillment of the function (the good case) is explanatorily and metaphysically prior to function failure (the bad case). We suggest that the etiological theory of functions renders this key premise plausible. However, Schellenberg rejects the etiological theory of functions and likewise the idea that the epistemic or warranting force of perceptual states is grounded in their being reliably linked to veridical perception. But then what supports the key premise? Schellenberg argues that accurate perception is a part of the nature of perceptual capacities because the nature of perceptual capacities is explained in terms of their function, and their function is to represent accurately. We suggest that Schellenberg is committed to an understanding of priority which doesn’t require any actual good cases—just possible ones. This reading, we argue, is too weak to support the key premise. Given Schellenberg’s commitments, it is not necessarily the case that perceptual states are evidence for a corresponding perceptual belief. Before concluding we discuss an overgeneralization objection. (shrink)

Celtic spirituality has a long and distinguished ancestry with its origins in pre-Christian times. It was inculturated among peoples in the far west of Europe, particularly in Ireland, Scotland and the north and south-west of England. It was different from Roman Christianity in distinct ways until the mid-7th century CE when Roman Christianity became the norm in Britain and Ireland. This spirituality has endured throughout the centuries and has experienced a revival from the latter half of the 20th century. From (...) its inception, it has been closely linked to the environment. Over the years many key aspects of Celtic spirituality have been integrated in many religious traditions and shows similarities with and can contribute to a new ethical perspective on environmental issues. This article investigates the current environmental crisis from a faith perspective and attempts to draw lessons from Celtic traditions of spirituality in a scientific age. (shrink)

The dominance of the Abrahamic tradition in contemporary analytic philosophy of religion has led some to call for greater exploration of alternatives to the traditional conception of God, such as Pantheism, Ultimism, and Axiarchism. While we think this call for alternatives is important, we go in a different direction. Rather than explore and defend alternative conceptions of God, we defend a range of fairly traditional but non-religious conceptions of God. This range of views, from deism to philosophical theism, enjoys a (...) variety of benefits over its religious competitors and deserves greater attention. (shrink)

In Contradiction advocates and defends the view that there are true contradictions (dialetheism), a view that flies in the face of orthodoxy in Western philosophy since Aristotle. The book has been at the center of the controversies surrounding dialetheism ever since its first publication in1987. This second edition of the book substantially expands upon the original in various ways, and also contains the author's reflections on developments over the last two decades. Further aspects of dialetheism are discussed in the companion (...) volume, Doubt Truth to be a Liar, also published byOxford University Press in 2006. (shrink)

According to our folk theory of lying, liars leak observable cues of their insincerity, observable cues that make it easy to catch a liar in real time. Various prominent social epistemologists rely on the correctness of our folk theory as empirically well-confirmed when building their normative accounts of the epistemology of testimony. Deception detection research in communication studies, however, has shown that our folk-theory is mistaken. It is not empirically well-confirmed but empirically refuted. Michaelian (2010) and Shieber (2012) have already (...) discussed some of this literature and its relevance for epistemology, especially for the most worked out reliance on our folk theory by Elizabeth Fricker (1994, 2016, 2017a, 2024). Fricker (2016) raises a reasonable objection to their presentations of the research: is the research ecologically valid? Do the experiments in the lab carry over to real life? This chapter conveys the methodology of the research, defends its ecological validity, and addresses further research on the nature and frequency of lies in ordinary life. Social epistemologists stand to gain from understanding the nuts and bolts of deception detection research and its findings. The chapter concludes with a detailed examination of Fricker’s relilance on folk theory in her “local reductionist” epistemology of testimony. Further areas of research relevant to social epistemology are listed. (shrink)

A series of arguments are presented by De Jong & Merckelbach which suggest that biological preparedness has been received significantly less critically than it should have been. I agree fully with their assessment. Cuthbert raises four questions about the applicability of the expectancy bias hypothesis to selective associations in human conditioning. This response argues that none of these four examples is necessarily problematic for the hypothesis.

This article is a response to Martin Orensanz’s argument that object-oriented ontology ought to accept the existence of matter as both a sensual and a real object. That matter can exist as a sensual object is a point immediately granted, since “sensual object” is such a broad term that nothing could be excluded from this designation. Yet I argue that this is not the case with respect to real objects, which must exist independently of any other entity that might encounter (...) them. This leads to a related debate on whether parthood is transitive, in which Orensanz takes up a recent argument of Daniel Korman while I defend the modified Aristotelian position that only the proximate parts of an object can be said to belong to it in the strict sense.

How does thinking in terms of truth contribute to our knowledge of the world? Moreover, what might the answers to this question tell us about truth itself? The aim of this paper is to canvas several roles of the truth concept for first-order inquiry (that is, inquiry into extra-linguistic and extra-mental reality) and then relate these answers to the ongoing inflationism-deflationism debate. I argue that the deflationary conception of truth is more versatile than is often appreciated, but there is nonetheless (...) one role that is uniquely inflationary. I call this role ‘representing semantic determinants’. In short, I argue that inflationism permits substantive explanations of the truth-conditional semantic facts and that such explanations can occasionally play a role in investigating certain first-order claims.

Philosophers are intellectual cannibals; they feed on the supposed errors of their colleagues. No harm in that, it might be said. With a sophistical argument like that of the Queen in Alice Through the Looking Glass to support the punishment of the innocent, progress in philosophy might be thought dependent on such voracious activities. The Queen thought that in replying to the claim that punishing the innocent was wrong one could say that if the victim really was innocent then that (...) produced a better universe than one which contained both the pain of the punishment and that of the original crime. In a similar way it might be argued that if the supposed errors of a colleague really exist, then their correction is beneficial; while if the errors do not exist then at least there is underlying agreement among philosophers, though perhaps not harmony. The sophistry, however, arises from the fact that in both cases there are other, and better, alternatives. The Queen unaccountably forgets that it would be still better in the case of innocence not to punish at all; and the philosophical apologist for intellectual cannibalism forgets, unaccountably, that it might be still better to advertise agreement rather than to feed on supposed errors which do not exist. For one thing, in that latter case the spurious conflict might positively conceal the real disagreements. Something of that latter kind happens in Timothy Sprigge’s comments on my views about William James ; James and Bradley:American Truth and British Reality, Open Court, 1994 ). I cannot, however, take much credit for stimulating Sprigge to adopt positions similar to mine for two reasons. First the apparent conflicts which conceal real agreement are relatively few, although quite important; second his own considered general view of James is certainly different from mine and marks the real disagreement between us. Accordingly I take two bites at this particular cherry; first to consider my supposed errors and second to identify the real differences between us. Timothy Sprigge claims to find a number of minor errors in my account, but I concentrate on the two major cases. (shrink)

The aim is to defend the starting?point of Marx's theory of class, which is located in a definition of the working class in the Communist Manifesto. It is a definition solely in terms of separation from productive resources and a need to sell one's labour power, and it is closely connected with Marx's thesis that the population in capitalism has a tendency to polarize. That thesis conflicts with the widely?held belief in the growth of a large middle class, unaccounted for (...) by Marx. Moreover, recent critics such as Elster, Roemer, and Cohen have argued that this definition fails even in its own terms. The definition is refurbished so as to withstand these objections. But is there any point in using it? Does it serve to pick out the exploited producers as Marx intended? It does, once due attention is given to the idea of the collective worker, which is central in the volume of Capital which Marx himself published. That idea makes plain that it is an irreducibly corporate entity which is productive and subject to exploitation. The structural conditions for membership of that entity remove Marx's view from any simple identification of working?class membership with manual or lowly labour. (shrink)

This paper compares the roles classical and intuitionistic logic play in restricting the free use of truth principles in arithmetic. We consider fifteen of the most commonly used axiomatic principles of truth and classify every subset of them as either consistent or inconsistent over a weak purely intuitionistic theory of truth.
