Permaculture is primarily a thinking tool for designing low carbon, highly productive systems. It originated in Australia in the 1970s and was conceived by Bill Mollison and David Holmgren as a response to the devastating effects of a temperate European agriculture on the fragile soils of an ancient antipodean landscape. Like the dust bowls of the Great Plains in the USA in the 1930s, an alien agriculture has the capacity to turn a delicately balanced ecology into desert. Their initial response (...) was to design a permanent agriculture with tree crops and other perennials inhabiting all the niches from the canopy to the ground cover and below. The soil is left untilled to establish its own robust micro-ecology. Key to this is that the land must be biodiverse and stable for future generations. From perennial tree crops, permaculture has developed into an integrated system of design that encompasses everything from agriculture, horticulture, architecture, and ecology, as well as economy and legal systems for businesses and communities.

Mathematicians tend to think of themselves as scientists investigating the features of real mathematical things, and the wildly successful application of mathematics in the physical sciences reinforces this picture of mathematics as an objective study. For philosophers, however, this realism about mathematics raises serious questions: What are mathematical things? Where are they? How do we know about them? Offering a scrupulously fair treatment of both mathematical and philosophical concerns, Penelope Maddy here delineates and defends a novel version of mathematical (...) realism. She answers the traditional questions and poses a challenging new one, refocusing philosophical attention on the pressing foundational issues of contemporary mathematics. (shrink)

This paper outlines a second-philosophical account of arithmetic that places it on a distinctive ground between those of logic and set theory.

Naturalism in Mathematics investigates how the most fundamental assumptions of mathematics can be justified. One prevalent philosophical approach to the problem--realism--is examined and rejected in favor of another approach--naturalism. Penelope Maddy defines this naturalism, explains the motivation for it, and shows how it can be successfully applied in set theory. Her clear, original treatment of this fundamental issue is informed by current work in both philosophy and mathematics, and will be accessible and enlightening to readers from both disciplines.

Mathematics depends on proofs, and proofs must begin somewhere, from some fundamental assumptions. For nearly a century, the axioms of set theory have played this role, so the question of how these axioms are properly judged takes on a central importance. Approaching the question from a broadly naturalistic or second-philosophical point of view, Defending the Axioms isolates the appropriate methods for such evaluations and investigates the ontological and epistemological backdrop that makes them appropriate. In the end, a new account of (...) the objectivity of mathematics emerges, one refreshingly free of metaphysical commitments. (shrink)

Richard Harland provides a lucid account of all the major movements in literary theory up to the late 1960s. In a lucid and accessible style, he unfolds a comprehensive "story" of literary theory in all its manifestations. Because contemporary literary theory depends heavily upon European thinkers, the book has an international focus, and its coverage extends from philosophers to social theorists to linguists. Harland explains the essential principles of each theoretical position, looking behind particular critical judgments and interpretations (...) in order to convey a core grasp of underlying positions.

The effort to fit simple logical truths–like `if it's either red or green and it's not red, then it must be green'–into Kant's account of knowledge turns up a position more subtle and intriguing than might be expected at first glance.

This paper explores women's accounts of prostitution in terms of the lived experience of the body, drawing on life story narratives and arts images created by women in the sex industry. These narratives show that women's experiences of prostitution constitute a spectrum of (dis)embodiment that is inflected, not determined, by settings and contexts. Theoretical approaches to embodiment were sought that acknowledged tensions between violation and a sense of empowerment. Therefore, the ontology of selling sex, and associated experiences such as violence, (...) drug use and self-harm are explored using feminist applications of Merleau-Ponty's notion of the `habit body'. A key focus is how the body is constituted by embodied experiences of abuse (e.g. the work of Parkins and of Weiss), and how women negotiate ownership of the body within commercial sex transactions. This highlights the process of repositioning the body by selling sex, in accordance with the accumulated experiences of the habit body. Thus, to borrow from Wendy Parkins, women perceive that they are acting meaningfully through the body, even when reproducing dynamics of objectification and dissociation. (shrink)

This chapter compares and contrasts Quine’s naturalism with the versions of two post-Quineans on the nature of science, logic, and mathematics. The role of indispensability in the philosophy of mathematics is treated in detail.

Feminist scholars have long critiqued the fashion industry’s ultra-thin beauty standards as harmful to women. Combining data from three qualitative studies of women’s clothing retailers—of bras, plus-size clothing, and bridal wear—we shift the analytical focus away from glamorized media images toward the seemingly mundane realm of clothing size standards, examining how women encounter, understand, and navigate these standards in their daily lives. We conceptualize clothing size standards as “floating signifiers,” given their lack of consistency within and across brands and the (...) extent to which women engage in identity work and body work in relation to them. Our findings indicate that the instability of these unregulated standards allows some women—particularly those with bodies located closest to the boundaries between size categories—to claim conformity to body ideals and to access some of the associated psychological, social, and material privileges. However, even as individual women may benefit by distancing themselves from stigmatized size categories, this pattern renders women’s body acceptance tenuous while simultaneously reinforcing hierarchies among women based on body size and shape.

We examine physicists’ charge of ad hocness against the Higgs mechanism in the standard model of elementary particle physics. We argue that even though this charge never rested on a clear-cut and well-entrenched definition of “ad hoc”, it is based on conceptual and methodological assumptions and principles that are well-founded elements of the scientific practice of high-energy particle physics. We further evaluate the implications of the recent discovery of a Higgs-like particle at the CERN’s Large Hadron Collider for the charge (...) of ad hocness against the Higgs mechanism. (shrink)

Many philosophers these days consider themselves naturalists, but it's doubtful any two of them intend the same position by the term. In Second Philosophy, Penelope Maddy describes and practices a particularly austere form of naturalism called "Second Philosophy". Without a definitive criterion for what counts as "science" and what doesn't, Second Philosophy can't be specified directly ("trust only the methods of science" for example), so Maddy proceeds instead by illustrating the behaviors of an idealized inquirer she calls the (...) "Second Philosopher". mhis Second Philosopher begins from perceptual common sense experimentation, theory formation and testing, working all the while to asses, correct and improve her methods as she goes. Second Philosophy is then the result of the Second Philosopher's investigations. Maddy delineates the Second Philosopher's approach by tracing her reactions to various familiar skeptical and transcendental views (Descartes, Kant, Carnap, late Putnam, van Fraassen), comparing her methods to those of other self-described naturalists (especially Quine), and examining a prominent contemporary debate (between disquotationalists and correspondence theorists in the theory of truth) to extract a properly second-philosophical line of thought. She then undertakes to practice Second Philosophy in her reflections on the ground of logical truth, the methodology, ontology and epistemology of mathematics, and the general prospects for metaphysics naturalized.

In lieu of an abstract, here is a brief excerpt of the content:Why the Phenomenology Remains FoundationalRobert Harland (bio)Keywordspsychology, cognitive-behavioral therapy (CBT), phenomenology, psychiatry, depressionDemian Whiting in his paper criticizes an exclusively cognitive approach to the treatment of emotional problems. There is no doubt that the cognitive model of the mind has been recently in the ascendancy and therapies based on it are to be found in almost every subspecialty of psychiatry. Cognitive-behavioral therapy (CBT) in particular is "discovered" as (...) being effective in everything from posttraumatic stress disorder to psychosis. The heartland of the approach is and remains anxiety and depression, the two most common emotional states that psychiatrists and psychologists are asked to deal with. As Dr. Whiting describes, leaving aside the behavioral aspects, the basic principle is about eliciting and challenging distorted cognitions. Cognitive theory suggests that distorted cognitions are the cause of, the substance of, and the maintaining factors in most if not all depression and anxiety.The author accepts that in certain cases distorted cognitions lead to an experience that is represented contra to reality. He suggests that in certain circumstances a cognitive therapist could help a patient to reappraise the world they find themselves in and by gathering evidence with the therapist, to challenge these distortions. So in depression, a patient sees themselves as worthless and their therapist suggests they gather evidence that helps them form a more balanced perspective. The cognition "I am worthless" is shown empirically to be a distortion. Whiting argues, correctly in my opinion, for the limitation of this approach. In doing so he argues against a growing psychological hegemony, one that sees itself as developing evidence-based practice that should be applied (on the back of national guidelines) to many presentations before or exclusively of others such as medication or alternative psychotherapeutic approaches.Whatever the outcome in the clinic, as opposed to the randomized controlled trials, many clinicians and health care managers are attracted to CBT because of its pragmatic, short-term, problem- and consumer-orientated nature. It has an approach tailored for most disorders and therefore fits very well within the organization of modern mental health services. With this background, nonclinical readers may more readily appreciate the potential target of Dr. Whiting's critique.Whiting suggests three examples where eliciting cognitions can at best be seen as secondary [End Page 247] to the problem in hand: First, where a drug (e.g., alcohol) or state (e.g., tiredness) directly causes an emotion; second, where an emotion causes a mistaken understanding of a situation; and third, where the representation is accurate but the response defective (e.g., the pedophile in his article, or more routinely a person particularly sensitive to anxiety). The phenomenology, before the prism of analysis, is that in all three cases the patients find themselves in an emotional state where any putative cognitive etiology is at best post hoc and at worst tautological. Furthermore, as the author states, in the cases where accurate representations elicit the wrong kinds of emotions, the question why cannot be answered by referring back to the person's representations.To answer the question of why someone is particularly sensitive to anxiety or gets aroused by children, Dr. Whiting points to several possibilities that all impact on treatment: First, the influence of noncognitive desires and emotions; second, physical contamination; third, an idiosyncratic or abnormal constitution; and fourth, a defective emotional acculturation. In all these cases, suggesting that the patient's problems will be resolved through altering eliciting cognitions seems illogical.The paper then preempts two criticisms from the cognitive approach. The first again rightly expands that, if a higher order evaluative level is proposed, this in no way answers a noncognitive critique. Either the higher level of evaluation is simply an unnecessary (or unpredictable) cognitive confirmation of a negative (or positive) representation, or the evaluation is a cognitive foil for an emotional reaction that is simply not cognitive; when someone says they are worthless they are merely giving voice to their depressed emotional state. Second, that retreating to a position where the cognitive approach is used to challenge distorted representations that are secondary to, and yet maintain, an inappropriate emotion may have a role, but does not mean that...

Many philosophers claim to be naturalists, but there is no common understanding of what naturalism is. Maddy proposes an austere form of naturalism called 'Second Philosophy', using the persona of an idealized inquirer, and she puts this method into practice in illuminating reflections on logical truth, philosophy of mathematics, and metaphysics.

Pursues the theoretical level of the two‐tiered epistemology of set theoretic realism, the level at which more abstract axioms can be justified by their consequences at more intuitive levels. I outline the pre‐axiomatic development of set theory out of Cantor's researches, describe how axiomatization arose in the course of Zermelo's efforts to prove Cantor's Well‐ordering Theorem, and review the controversy over the Axiom of Choice. Cantor's Continuum Hypothesis and various questions of descriptive set theory were eventually shown to be independent (...) of the standard axioms, and new axiom candidates—Gödel's Axiom of Constructibility, on the one hand, determinacy and large cardinal axioms, on the other—offer dramatically different solutions. This situation presents a new epistemic challenge to the set theoretic realist: on what grounds can we adjudicate between new axiom candidates? (shrink)

Outlines a physicalistic version of set theoretic realism, and compares and contrasts it with Field's nominalism, with structuralism, and with modalism. I conclude that, despite metaphysical differences, versions of all these views share the new challenge raised in Ch. 4: how are new axiom candidates to be rationally evaluated?

Begins with a review of Benacerraf's metaphysical challenge to mathematical realism based on sets: how, for example, can number theory be the study of particular sets when other sets with the same structural relations would seem to do just as well? The set theoretic realist gives the straightforward response that numbers are not particular sets, but properties of sets. I close with a digression on the prospects for ‘Frege numbers’—i.e. numbers construed as proper classes.

Mathematical axioms have traditionally been thought of as obvious or self-evident truths, but current set theoretic work in the search for new axioms belies this conception. This raises epistemological questions about what other forms of justification are possible, and how they should be judged.

Begins with a presentation and elaboration of Benacerraf's epistemic challenge to realism: how can we gain knowledge of an acausal world of non‐spatio‐temporal abstracts? I then outline a theory of perception based in part on neurological theories of Hebb and developmental evidence from Piaget, and I argue in these terms that we can, in fact, perceive sets of medium‐sized physical objects. This account of perception is elaborated into an account of physical and mathematical intuition, faculties that produce various rudimentary beliefs (...) that underlie the simplest physical and set theoretic assumptions. I conclude by comparing and contrasting this epistemology with some controversial passages from Gödel's writings. (shrink)

The early sections describe the pre‐theoretic realism of the mathematician, survey the basic forms of realism in philosophy, and attempt to disentangle the issues of realism from debates over the nature of truth. The final section begins by laying out traditional Platonism, intuitionism, and formalism. Quine's famous critique of Carnap's conventionalism then leads to Quine's realism, and Putnam's developments thereof, while a different sort of mathematical realism is found in Gödel's writings. Set theoretic realism emerges as an effort to build (...) on the strengths of Quine's and Gödel's realisms, while avoiding their weaknesses and filling in their lacunae. (shrink)

It’s often said that set theory provides a foundation for classical mathematics because every classical mathematical object can be modeled as a set and every classical mathematical theorem can be proved from the axioms of set theory. This is obviously a remarkable mathematical fact, but it isn’t obvious what makes it ‘foundational’. This paper begins with a taxonomy of the jobs set theory does that might reasonably be regarded as foundational. It then moves on to category-theoretic and univalent foundations, exploring (...) to what extent they do these same jobs, and to what extent they might do other jobs also reasonably regarded as foundational.

What Do Philosophers Do? takes up the leading arguments for radical skepticism from an everyday point of view. A range of philosophical methods are examined and employed, for a revealing portrait of what philosophers do, and perhaps a quiet suggestion for what they should do, for what they do best.

A recently popular formulation of the Higgs naturalness principle prohibits delicate cancellations between running renormalized Higgs mass parameters and EFT matching corrections, by contrast with the principle’s original formulation, which prohibits delicate cancellations between the bare Higgs mass parameter and its quantum corrections. While the need for this latter cancellation is sometimes viewed as unproblematic since bare parameters are thought by some to be divergent and unphysical, renormalized parameters are finite and measurable, and the need for delicate cancellations between the (...) renormalized Higgs mass parameter and EFT matching corrections is therefore considered by some to constitute a more salient formulation of the Higgs naturalness problem. Here, we argue that to the contrary, the need for fine tuning of the renormalized Higgs mass parameter is an eliminable, unphysical artifact of renormalization scheme, and that this severely weakens the grounds for regarding it as a problematic instance of fine tuning. In doing so, we highlight what we take to be a number of important conceptual lessons about the physical interpretation of model parameters in QFT. (shrink)

This talk surveys a range of positions on the fundamental metaphysical and epistemological questions about elementary logic, for example, as a starting point: what is the subject matter of logic—what makes its truths true? how do we come to know the truths of logic? A taxonomy is approached by beginning from well-known schools of thought in the philosophy of mathematics—Logicism, Intuitionism, Formalism, Realism—and sketching roughly corresponding views in the philosophy of logic. Kant, Mill, Frege, Wittgenstein, Carnap, Ayer, Quine, and Putnam (...) are among the philosophers considered along the way. (shrink)

My goal here is to explore the relationship between pure and applied mathematics and then, eventually, to draw a few morals for both. In particular, I hope to show that this relationship has not been static, that the historical rise of pure mathematics has coincided with a gradual shift in our understanding of how mathematics works in application to the world. In some circles today, it is held that historical developments of this sort simply represent changes in fashion, or in (...) social arrangements, governments, power structures, or some such thing, but I resist the full force of this way of thinking, clinging to the old school notion that we have gradually learned more about the world over time, that our opinions on these matters have improved, and that seeing how we reached the point we now occupy may help us avoid falling back into old philosophies that are now no longer viable. In that spirit, it seems to me that once we focus on the general question of how mathematics relates to science, one observation is immediate: the march of the centuries has produced an amusing reversal of philosophical fortunes. Let me begin there. In the beginning, that is, in Plato, mathematical knowledge was sharply distinguished from ordinary perceptual belief about the world. According to Plato’s metaphysics, mathematics is the study of eternal and unchanging abstract Forms,1 while science is uncertain and changeable opinion about the world of mere becoming. Indeed, in Plato’s lights, of the two, only mathematics deserves to be called ‘knowledge’ at all! Of course if sense perception cannot give us knowledge, if mathematics is not about perceivable things, then Plato owes us an account of how we ordinary humans achieve this wonderful insight into the properties of the abstract world of Forms. Plato’s answer is that we do not actually acquire mathematical knowledge at all; rather, we recollect it from a time before birth, when our souls, unencumbered by physical bodies, were free to commune with the Forms, and not just the mathematical ones, either – also Truth, Beauty, Justice, the Good, and so on.2 Whatever appeal this position may have held for the ancient Greeks, it will not begin to satisfy a contemporary, scientifically minded philosopher.. (shrink)

The goal of this paper is to sketch a distinctive version of naturalism in the philosophy of science, both by tracing historical antecedents and by addressing contemporary objections.

Naturalism in philosophy is sometimes thought to imply both scientific realism and a brand of mathematical realism that has methodological consequences for the practice of mathematics. I suggest that naturalism does not yield such a brand of mathematical realism, that naturalism views ontology as irrelevant to mathematical methodology, and that approaching methodological questions from this naturalistic perspective illuminates issues and considerations previously overshadowed by (irrelevant) ontological concerns.
