This chapter focuses on alternative logics. It discusses a hierarchy of logical reform. It presents case studies that illustrate particular aspects of the logical revisionism discussed in the chapter. The first case study is of intuitionistic logic. The second case study turns to quantum logic, a system proposed on empirical grounds as a resolution of the antinomies of quantum mechanics. The third case study is concerned with systems of relevance logic, which have been the subject of an especially detailed reform (...) program. Finally, the fourth case study is paraconsistent logic, perhaps the most controversial of serious proposals. (shrink)

This is the most comprehensive book ever published on philosophical methodology. A team of thirty-eight of the world's leading philosophers present original essays on various aspects of how philosophy should be and is done. The first part is devoted to broad traditions and approaches to philosophical methodology. The entries in the second part address topics in philosophical methodology, such as intuitions, conceptual analysis, and transcendental arguments. The third part of the book is devoted to essays about the interconnections between philosophy (...) and neighbouring fields, including those of mathematics, psychology, literature and film, and neuroscience.

‘Feminist logic’ may sound like an impossible, incoherent, or irrelevant project, but it is none of these. We begin by delineating three categories into which projects in feminist logic might fall: philosophical logic, philosophy of logic, and pedagogy. We then defuse two distinct objections to the very idea of feminist logic: the irrelevance argument and the independence argument. Having done so, we turn to a particular kind of project in feminist philosophy of logic: Valerie Plumwood's feminist argument for a relevance (...) logic. Plumwood's work serves as our primary case study as we turn to the project of considering three different ways we might understand her argument and revisionist arguments like it: as a priori theorizing, as ameliorative conceptual engineering, or as instances of anti-exceptionalist approaches to logic. After arguing that the anti-exceptionalist approach seems to provide the most promising means of understanding the kind of project undertaken in a feminist challenge to classical logic, we briefly address the consequences that this might have for logic instruction. Here, we argue for the perhaps unexpected conclusion that feminist programs ought to offer more, not less, instruction in logic for those who take interest. (shrink)

There is a robust tendency within the contemporary feminist mainstream to argue against and ultimately reject the so-called ‘dualising or dualist philosophy’ since it is the supportive paradigm background for any gender discrimination originated from the hegemonic sovereignty of masculinity over femininity. In this paper, having dived deeper into the feminist critical depiction of the logical binarist foundation on which the dualising philosophy is said to be well-grounded, I will proceed to portray and examine a sequence of doctrines that feminist (...) philosophers have developed to shed light on the fact that the hegemonic sovereignty of masculinity over femininity has been theoretically initiated from the logical disjunction 'p or not p' to masculinity essentialism. Finally, I will end by pointing to a tension between underlying assumptions of the feminist sequentialist approach and what feminists themselves claim to adhere to as the highest ideal: non-naturalising gender differences.

Philosophy’s adversarial argumentation style is often noted as a factor contributing to the low numbers of women in philosophy. I argue that there is a level of adversariality peculiar to philosophy that merits specific feminist examination, yet doesn’t assume controversial gender differences claims. The dominance of the argument-as-war metaphor is not warranted, since this metaphor misconstrues the epistemic role of good argument as a tool of rational persuasion. This metaphor is entangled with the persisting narrative of embattled reason, which, in (...) turn, is linked to the sexism-informed narrative of the “man of reason” continually warding off or battling “feminine” unreason. (shrink)

Reason has regularly been portrayed and understood in terms of images and metaphors that involve the exclusion or denigration of some element-body, passion, nature, instinct-that is cast as "feminine." Drawing upon philosophical insight into metaphor, I examine the impact of this gendering of reason. I argue that our conceptions of mind, reason, unreason, female, and male have been distorted. The politics of "rational" discourse has been set up in ways that still subtly but powerfully inhibit the voice and agency of (...) women. (shrink)

I this paper, I discuss Plumwood’s feminist logic program. I argue both in favor of her general stance in feminist philosophy of logic and her more specific feminist critique of classical logic. Plumwood’s general position is in opposition with (I think it’s safe to say) the prevailing view in analytic philosophy about the relation between formal logic and feminist theory, according to which feminist theory cannot say anything about or against logic proper, since the issues of oppression are external to (...) logic as a (formal) discipline. Connected to this externalism is a non-Plumwoodian view that “feminist logic” either doesn’t mean anything, or that it has some figurative meaning. Concerning Plumwood’s (I think it’s safe to say) not widely accepted feminist critique of classical logic, I propose an interpretation according to which classical logic is oppressive only when it’s used to describe a particular, “dualized” or “dualizable”, kind of notions. In accordance with this understanding, I consider five features of oppressive differentiations as proposed by Plumwood, arguing that two of them don’t concern negation, the feminist critique of which operator Plumwood is mostly (in)famous for.

The form of the sentence, as it is understood in contemporary semantics and linguistics, is functional. This paper interprets the metaphors in which Frege shows what the functional sentence means, arguing that Frege's sentence is neither an adequate translation of natural language nor of use in feminist theorizing.

This paper is part of a larger project of recovering the work of women thinkers. Heloise has traditionally been read as either a foil of Abelard or his intellectual appendage. In this paper, I present her views on love, religious devotion, and language as an alternative to philosophic method as it is conceived by Abelard.

Three misrepresentations of informal and formal logic by two feminist writers are discussed. Andrea Nye's criticism that the semantics for formal logic abstracts from context is a misrepresentation of formal logic because Nye ignores the development of intensional logics. Second, Nye's criticism that informaIlogicians ignore the origins of arguments is a misrepresentation of fallacy theory. Prominent writers in the field specifiy numerous cases where the origins of an argument are relevant to its evaluation. Third, Valerie Plumwood's criticism that negation in (...) classical logic rests on an exclusivistic dualism that encourages the exclusion of women is shown to be false. (shrink)

The traditional sciences have always had trouble with ambiguity. To overcome this barrier, ‘science’ has imposed “enabling constraints”—hidden assumptions which are given the status of ceteris paribus. Such assumptions allow ambiguity to be bracketed away at the expense of transparency. These enabling constraints take the form of uncritically examined presuppositions, which we refer to throughout the article as “uceps.” The meanings of the various uceps are shown via their applicability to the science of climate change. Second order science examines variations (...) in values assumed for these uceps and looks at the resulting impacts on related scientific claims. Second order science reveals hidden issues, problems and assumptions which all too often escape the attention of the practicing scientist. This article lays out initial foundations for second order science, its ontology, methodology, and implications. (shrink)

While contemporary feminist philosophical discussions focus on the oppressiveness of universality which obliterates “difference,” the complete demise of universality might hamper feminist philosophy in its political project of furthering the well-being of all women. Dewey's thoroughly functionalized, relativized, and fallibilized understanding of universality may help us cut universality down to size while also appreciating its limited contribution. Deweyan universality may signify the ongoing search for a genuinely common language in the midst of difference.

More than one philosopher has expressed puzzlement at the very idea of feminist epistemology. Metaphysics and epistemology, sometimes called the 'core' areas of philosophy, are supposed to be immune to questions of value and justice. Nevertheless, many philosophers have raised epistemological questions starting from feminist-motivated moral and political concerns. The field is burgeoning; a search of the Philosopher's Index reveals that although nothing was published before 1981 that was categorized as both feminist and epistemology, soon after, the rate of publication (...) in feminist epistemology rose to between 15 and 25 articles per year.1 At the same time, social epistemology was also beginning to grow as a separate identifiable field of inquiry.

Self-trust is a necessary condition of personal autonomy and self-respect. Self-trust involves a positive sense of the motivations and competence of the trusted person; a willingness to depend on him or her; and an acceptance of vulnerability. It does not preclude trust in others. A person may be rightly said to have too much self-trust; however core self-trust is essential for functioning as an autonomous human being.

This essay begins with a critique of the Critical-Logical model dominant in contemporary argumentation theory. The concerns raised stem primarily from considerations brought by several feminist thinkers including Carol Gilligan, Karen Warren, Deborah Tannen and, most especially, Andrea Nye. It is argued that, in light of these considerations, and concerns of essentialism or non-essentialism notwithstanding, that the Critical-Logical model is liable to dis-enfranchise a significant part of the population with regard to modes and styles of reasoning. The solution is found (...) in coalescent reasoning, an approach to argumentation that focuses on finding agreement rather than emphasizing disagreement and criticism. (shrink)

Continental philosophy of science has developed alongside mainstream analytic philosophy of science. But where continental approaches are inclusive, analytic philosophies of science are not–excluding not merely Nietzsche’s philosophy of science but Gödel’s philosophy of physics. As a radicalization of Kant, Nietzsche’s critical philosophy of science puts science in question and Nietzsche’s critique of the methodological foundations of classical philology bears on science, particularly evolution as well as style (in art and science). In addition to the critical (in Mach, Nietzsche, Heidegger (...) but also Husserl just to the extent that continental philosophy of science tends to depart from a reflection on the crisis of foundations), other continental philosophies of science include phenomenology (Husserl, Bachelard, Merleau‐Ponty, etc.) and hermeneutics (Heidegger, Gadamer, Heelan, etc.), especially incorporating history of science (Nietzsche, Mach, Duhem, Butterfield, Feyerabend, etc.). Examples are drawn from the philosophy of sciences (chemistry, geology, and biology) other than physics. (shrink)

Is it possible for one and the same person to be a feminist and a logician, or does this entail a psychic rift of such proportions that one is plunged into an endless cycle of self-contradiction? Andrea Nye's book, Words of Power (1990), is an eloquent affirmation of the psychic rift position. Although eloquent, I believe it is mistaken in certain serious ways, which I shall address in this paper.Nye advances this position in her concluding essay to Words of Power (...) (Ibid.). In brief, her position is that the logical enterprise is inherently self-contradictory for feminist thinkers. Feminists who attempt to use logic to demonstrate its shortcomings are doomed to failure; arguing against logical claims is self-defeating, for the critic will be sucked into the maelstrom of logical tradition. Hydra-headed, the logical monster will thrive rather than perish under the sharpened edge of argument; hence the critic succeeds only in strengthening the very endeavour whose shortcomings she attempts to expose. This is guaranteed to happen, according to Nye, because in entering the debate, one is thereby committed to the terms of the debate. The critic herself will be devoured in the process, for logic was constructed to eliminate the voices and concerns of women. ‘The feminist logician speaks from a script in which the master always wins' (Ibid., p. 180).If feminists cannot use logic itself to attack the arrogant and unsupportable assumptions of logic, what are our alternatives? Nye sketches two alternatives - one is to simply turn our backs on logic, ignoring it in all of its masculine arrogance, and talk among ourselves in our own women's language about our own concerns. Nye does not recommend this alternative, for although it escapes the criticism of arrogance, it does so at the price of impotence. What she does recommend is the second alternative, that as feminists we direct our energy towards reading other people's work, including that of the logicians, and responding to it in ways ‘that can mortally wound’ (Ibid., p. 184) the authors; women, Nye believes, are particularly adept at reading. ‘It is a skill we have perfected’ (Ibid.) in the course of our oppression.In what follows, I shall discuss Nye's proscription of logic as well as her perceived alternatives of a woman's language and reading. This will be followed by a discussion more sharply focused on Nye's feminist response to logic, namely, her claim that feminism and logic are incompatible. I will end by offering a sketch of a class in the life of a feminist teaching logic, a sketch which is both a response to Nye (in Nye's sense of the word) and a counter-example to her thesis that logic is necessarily destructive to any genuine feminist enterprise.

The logical empiricists often appear as a foil for feminist theories. Their emphasis on the individualistic nature of knowledge and on the value-neutrality of science seems directly opposed to most feminist concerns. However, several recent works have highlighted aspects of Carnap's views that make him seem like much less of a straightforwardly positivist thinker. Certain of these aspects lend themselves to feminist concerns much more than the stereotypical picture would imply.

In this article, I aim to demonstrate that moral responsibility theory produces, legitimates, and even magnifies the considerable social injustice that accrues to disabled people insofar as it implicitly and explicitly promotes a depoliticized ontology of disability that construes disability as a naturally disadvantageous personal characteristic or deleterious property of individuals rather than identifies it as an effect of power, an apparatus. In particular, I argue that the methodological tools of “analytic” philosophy that philosophers of moral responsibility theory employ to (...) establish the philosophical domain in which they engage have distinctly detrimental effects on disabled people.

Much of feminist philosophy of language so far can be described as critical—critical either of language itself or of philosophy of language, and calling for change on the basis of these criticisms. Those making these criticisms suggest that the changes are needed for the sake of feminist goals — either to better allow for feminist work to be done or, more frequently, to bring an end to certain key ways that women are disadvantaged. In this entry, I examine these criticisms. (...) I also examine work by feminists that seems to suggest some of the criticisms are misplaced: that, for example, philosophy of language is better able to help in feminist projects than critics suppose. My focus in this entry will generally be on the analytic tradition. For continental approaches, see the entries on feminist approaches to the intersection of analytic and continental philosophy , feminist approaches to the intersection of pragmatism and continental philosophy.

Logicians disagree about how validity—the very heart of logic—should be understood. Many different formal systems have been born due to this disagreement. This thesis examines how teachers explain the subject matter of logic to students in introductory logic textbooks, and demonstrates the different explanations teachers use. These differences help explain why logicians have different intuitions about validity.

In the present article, I offer a new reading of Hannah Arendt’s The Origins of Totalitarianism, specifically her argument that ideologies such as racism engender totalitarianism when the lonely and disenfranchised laborers of modern society develop a pathological fixation on formal logic, which I term “logomania.” That is, such logical deductions, from horrifically false premises, are the closest thing to thinking that individuals can engage in after their psyches, relationships, and communities have broken down. And it is only thus that (...) totalitarianism can achieve power, since it offers at least some form of connectedness and meaning, regardless how terrifying and violent. The danger persists, clearly, with the resurgence of the far Right, including in the extraordinary regime of Trump in the United States. From this I conclude that, along with the admirable calls to fight loneliness and rebuild our communities, we should also supplement all formal logical instruction and community education with instruction in creative thinking (including aesthetics), thereby discouraging the monomaniac reliance on formal logic as inadvertent weapon of totalitarianism.

An introduction to philosophy of language since Frege, focusing on the 20th century.

Logic is the systematic study of patterns of correct inference. The first treatise on logic is Aristotle's Prior Analytics , written around 350 B.C. and there are remarkable similarities between the way he presented his theory of valid arguments and the way it is still taught today. He analyzes the form of various inferences and then illustrates them with concrete examples. He begins with very simple cases.

Continental philosophies of science tend to exemplify holistic themes connecting order and contingency, questions and answers, writers and readers, speakers and hearers. Such philosophies of science also tend to feature a fundamental emphasis on the historical and cultural situatedness of discourse as significant; relevance of mutual attunement of speaker and hearer; necessity of pre-linguistic cognition based in human engagement with a common socio-cultural historical world; role of narrative and metaphor as explanatory; sustained emphasis on understanding questioning; truth seen as horizonal, (...) aletheic, or perspectival; and a tolerance for paradoxical and complex forms of expression. Continental philosophy of science is thus more comprehensive than philosophy of science in the analytic tradition, including (and as analytic philosophy of science does not tend to include) perspectives on the history of science as well as the social and practical dimensions of scientific discovery. Where analytic philosophy is about reducing or, indeed, eliminating the perennial problems of philosophy, Continental philosophy is all about thinking and that will mean, as both Heidegger and Nietzsche emphasize, making such problems more not less problematic.

It has been accepted for some time within Communication Theory that there are identifiable differences in how men and women communicate. This acceptance obtains both within the academic world and even more so within the realm of folk Communication Theory. I argue that the gender-identified differences run along distinct poles. The first major pole concerns the objectives meant to be achieved by argument: is it deciding who is right? Or, what the issue really is? Or, how a disagreement can or (...) should be resolved? The second major aspect concerns the communi­cative tools used in settling differences and understanding positions. If the genders have different rules of communi­cation, which rules will be followed? What sorts of arguments and evidence will be allowed? If classically mascu­line criteria are applied, then how can classically feminine voices be heard? It is argued that these issues do not loom nearly so large when gender is not confused with sex.

Recent work linking feminist epistemology with social epistemology draws attention to the role of status and power in understanding knowledge and reasoning in social context. I argue that considerations of social justice require better understandings of two particular components of reasoning and social context: abstraction—who gets to abstract, how, and why? the individual-social distinction—how do particular understandings of this distinction serve to minimize or elucidate the role of status and power?

Val Plumwood’s 1993 paper, “The politics of reason: towards a feminist logic” (hence- forth POR) attempted to set the stage for what she hoped would begin serious feminist exploration into formal logic – not merely its historical abuses, but, more importantly, its potential uses. This work offers us: (1) a case for there being feminist logic; and (2) a sketch of what it should resemble. The former goal of Plumwood’s paper encourages feminist theorists to reject anti-logic feminist views. The paper’s (...) latter aim is even more challenging. Plumwood’s critique of classical negation (and classical logic) as a logic of domination asks us to recognize that particular logical systems are weapons of oppression. Against anti-logic feminist theorists, Plumwood argues that there are other logics besides classical logic, such as relevant logics, which are suited for feminist theorizing. Some logics may oppress while others may liberate. We provide details about the sources and context for her rejection of classical logic and motivation for promoting relevant logics as feminist.
