Elliott Sober is both an empiricist and an instrumentalist. His empiricism rests on a principle called actualism, whereas his instrumentalism violates this. This violation generates a tension in his work. We argue that Sober is committed to a conflicting methodological imperative because of this tension. Our argument illuminates the contemporary debate between realism and empiricism which is increasingly focused on the application of scientific inference to testing scientific theories. Sober’s position illustrates how the principle of actualism drives a wedge between (...) two conceptions of scientific inference and at the same time brings to the surface a deep conflict between empiricism and instrumentalism.

We apply Benacerraf’s distinction between mathematical ontology and mathematical practice to examine contrasting interpretations of infinitesimal mathematics of the seventeenth and eighteenth century, in the work of Bos, Ferraro, Laugwitz, and others. We detect Weierstrass’s ghost behind some of the received historiography on Euler’s infinitesimal mathematics, as when Ferraro proposes to understand Euler in terms of a Weierstrassian notion of limit and Fraser declares classical analysis to be a “primary point of reference for understanding the eighteenth-century theories.” Meanwhile, scholars like (...) Bos and Laugwitz seek to explore Eulerian methodology, practice, and procedures in a way more faithful to Euler’s own. Euler’s use of infinite integers and the associated infinite products are analyzed in the context of his infinite product decomposition for the sine function. Euler’s principle of cancellation is compared to the Leibnizian transcendental law of homogeneity. The Leibnizian law of continuity similarly finds echoes in Euler. We argue that Ferraro’s assumption that Euler worked with a classical notion of quantity is symptomatic of a post-Weierstrassian placement of Euler in the Archimedean track for the development of analysis, as well as a blurring of the distinction between the dual tracks noted by Bos. Interpreting Euler in an Archimedean conceptual framework obscures important aspects of Euler’s work. Such a framework is profitably replaced by a syntactically more versatile modern infinitesimal framework that provides better proxies for his inferential moves. (shrink)

Modern computing is generally taken to consist primarily of symbol manipulation. But symbols are abstract, and computers are physical. How can a physical device manipulate abstract symbols? Neither Church nor Turing considered this question. My answer is that the bit, as a hardware-implemented abstract data type, serves as a bridge between materiality and abstraction. Computing also relies on three other primitive—but more straightforward—abstractions: Sequentiality, State, and Transition. These physically-implemented abstractions define the borderline between hardware and software and between physicality and (...) abstraction. At a deeper level, asking how a physical device can interact with abstract symbols is the wrong question. The relationship between symbols and physical devices begins with the realization that human beings already know what it means to manipulate symbols. We build and program computers to do what we understand to be symbol manipulation. To understand what that means, consider a light switch. A light switch doesn’t turn a light on or off. Those are abstractions. Light switches don’t operate with abstractions. We build light switches, so that when flipped, the world is changed in such a way that we understand the light to be on or off. Similarly, we build computers to perform operations that we understand as manipulating symbols. (shrink)

This paper offers a new way to make sense of disagreement expansion from a polylogical perspective by incorporating various places in addition to players and positions into the analysis. The concepts build on prior implicit ideas about disagreement space by suggesting how to more fully account for argumentative context, and its construction, in large-scale complex controversies. As a basis for our polylogical analysis, we use a New York Times news story reporting on an oil train explosion—a significant point in the (...) broader controversy over producing oil and gas via hydraulic fracturing.

In "Exploring 'Atlas Shrugged': Ayn Rand’s Magnum Opus (2021)," Edward W. Younkins has compiled several of his essays on Ayn Rand's novel "Atlas Shrugged." The volume leads with an “Introduction” that contextualizes the importance of "Atlas Shrugged" and provides a detailed overview of each chapter. Chapter 1 gives a synopsis of the novel. Chapter 2 examines "Atlas Shrugged" as both philosophy and literature. In Chapter 3, Younkins looks at it as a treatise on economics before turning in Chapter 4 to (...) consider it as a story about business. Chapter 5 discusses it as a novel about and a blueprint for social change. In the “Appendix,” Younkins provides an overview of the philosophy of Objectivism. "Exploring 'Atlas Shrugged': Ayn Rand’s Magnum Opus" is a significant contribution and highly recommended for instructors, students, and the general reader. Younkins’s volume can serve as an instructor’s resource for those teaching "Atlas Shrugged," as a companion text for students in those courses, or as a stand-alone book for readers who are familiar with the book and are interested in a fresh examination of this timeless novel from a thematic, structural, and character-development point of view.

Kotarbiński is one of the leading figures in the Lvov-Warsaw school of Polish philosophy. We summarize the development of Kotarbiński’s thought from his early nominalism and ‘pansomatistic reism’ to the later doctrine of ‘temporal phases’. We show that the surface clarity and simplicity of Kotarbiński’s writings mask a number of profound philosophical difficulties, connected above all with the problem of giving an adequate account of the truth of contingent (tensed) predications. The paper will examine in particular the attempts to resolve (...) these difficulties on the part of Leśniewski. It will continue with an account of the relations of Kotarbińskian reism to the ontology of things or entia realia defended by the later Brentano. Kotarbiński’s identification of Brentano as a precursor of reism is, it will be suggested, at least questionable, and the paper will conclude with a more careful attempt to situate the Brentanian and Kotarbińskian ontologies within the spectrum of competing ontological views.

A comprehensive and practical study tool, introducing Kant's thought and key works and exploring his continuing influence.

Against the backdrop of the English reception of Locke’s Essay, stands a little-known philosophical dispute between two seventeenth-century women writers: Mary Astell (1666-1731) and Damaris Cudworth Masham (1659-1708). On the basis of their brief but heated exchange, Astell and Masham are typically regarded as philosophical adversaries: Astell a disciple of the occasionalist John Norris, and Masham a devout Lockean. In this paper, I argue that although there are many respects in which Astell and Masham are radically opposed, the two women (...) also have a surprising amount in common. Rather than interpret their ideas solely in relation to the ‘canonical’ philosophies of the time – Lockean empiricism and Malebranchean occasionalism – I examine the ways in which Astell and Masham are influenced by the metaphysical theories of the Cambridge Platonists, Ralph Cudworth and Henry More. On this basis, I argue that a remarkably similar theological approach underlies the metaphysical and feminist arguments of Astell and Masham. (shrink)

What is the future of religion ? Some expect the resurgence and ultimate triumph of this or that fundamentalism . Some expect the religious phenomenon itself to weaken and die, a casualty to the science of our day. Others, observing the history of religion, expect that it will continue to evolve, inextricably connected to and yet clearly distinct from its past. If such an evolution occurs, what will religions of the future be like?

This essay critiques the return to objects posited by certain new materialisms, most specifically the speculative realism of Harman, Meillassoux and Brassier. It argues that their “non-relational” and “autonomous” ontology represents a neo-positivist conception of reality. In place of such an atomistic ontology, I will suggest that the new materialisms develop a more productive, “non-reductive materialism”—a term drawn from analytic philosophy of mind. I will interpret Merleau-Ponty and Jean-Luc Nancy as crucial examples of such a materialism on the continental side. (...) Rather than being based on the non-relational innerness of an object, this position instead takes into account matter’s fundamentally extended nature. Confirmed by examples such as the growing evidence for neuroplasticity, the externalist, non-reductive view advances the new materialist argument that matter is “agentive” and “active” rather than “mechanic” and “passive,” without slipping into an anti-social-constructionist biologism or behaviorism.

According to a standard view of the second law of thermodynamics, our belief in the second law can be justified by pointing out that low entropy macrostates are less probable than high entropy macrostates, and then noting that a system in an improbable state will tend to evolve toward a more probable state. I would like to argue that this justification of the second law of thermodynamics is fundamentally flawed, and will show that some puzzles sometimes associated with the second (...) law are merely artifacts of this incorrect justification.

David Hume has traditionally been regarded as a skeptic, perhaps the most formidable in the history of Western philosophy. Since the publication of Norman Kemp Smith's Philosophy of David Hume in 1941, however, there has been an increasing tendency to downplay the skeptical dimension of Hume's philosophy, in some cases to the point of denying that Hume is a serious skeptic, or even a skeptic at all. Much of the motivation for a nonskeptical reading of Hume comes from recognition of (...) his endorsement of empirical science and his own project of founding a "science of man." Recent scholarship has, in my opinion correctly, recognized Hume as a constructive rather than a purely destructive thinker. Yet this recognition has, in my opinion incorrectly, gone hand in hand with a tendency to overlook or deny the skeptical side of Hume's thought. In this work, I address the issue of Hume's skepticism. I believe that though the issue of Hume's skepticism is more complicated than is suggested by some of those who interpret him as a skeptic, nevertheless the traditional view is more true to Hume's texts than is a nonskeptical interpretation. I argue, on the basis of a reading of the Treatise of Human Nature and Enquiry Concerning Human Understanding, that Hume is a serious theoretical skeptic with regard to much of our alleged knowledge. In saying that Hume is a serious theoretical skeptic I mean that Hume's skeptical pronouncements are in general sincere, not ironic, Hume's skepticism extends to a large part of our alleged knowledge, and Hume's skepticism is a result of his substantive philosophical views. In saying that Hume is a serious theoretical skeptic I mean that though Hume doesn't prescribe eschewal of beliefs that are not rationally justified, he thinks that much of our alleged knowledge essentially involves beliefs that cannot be rationally justified and that hence much of our alleged knowledge is not knowledge at all.

My dissertation explores some issues of Aristotle’s philosophy, regarding the functionalist interpretation developed by Hilary Putnam and Martha C. Nussbaum as a valuable starting point. In Chapter One, I analyze some families of interpretations of Aristotle’s “psuchology” proposed in the second half of the 20th century in the context of the philosophy of mind. I show how some aspects of Aristotle’s thought, which are correctly grasped by the dualistic as well as by the physicalist interpretation, are later resumed and harmonized (...) by functionalism into a coherent doctrine. In Chapter Two it is worth to set out an analysis of Aristotle’s hylomorphism. I take into account homonymy, which is traditionally conceived as being in conflict with hylomorphism. I show not only how homonymy is rather a consequence of hylomorphism, but also how it allows to highlight that hylomorphism, if properly conceived, should be regarded as an ontological thesis with predicative consequences. In this regard, I suggest my own definition of hylomorphism. In Chapter Three, I take into account Aristotle’s final causation, comparing it with contemporary naturalism. I hold that teleology demonstrates Aristotle’s anti-reductionism and, in particular, the fact that he attributes causal efficacy to natural forms and ends. I criticize functionalism for having regarded Aristotle’s formal and final causes as being just explanatory, whereas, on the contrary, Aristotle conceives such explanatory character to derive from their genuine causal role. I formulate my own position, which I label as “logical compatibilism”. I hint at how the functional analysis of living organism may establish some points of contact between Aristotle’s and Darwin’s analysis. I recognize that functionalism correctly grasps the functional roles Aristotle attributes to matter and form and that it translates such an account in a valuable philosophical doctrine. Nevertheless, functionalism confines itself within the framework of contemporary philosophy of mind and fails to comprehend Aristotle’s anti-reductionist naturalism as regards biological life and nature in general.
