This chapter begins with a discussion of humanist criticisms of scholastic logic. It then discusses the evolution of the scholastic tradition and the influence of Renaissance Aristotelianism, Descartes and his influence, the Port-Royal Logic, the emergence of a logic of cognitive faculties, logic and mathematics in the late 17th century, Gottfried Wilhelm Leibniz’s role in the history of formal logic, and Kant’s influence on logic.
Indian Logic
The chapter is an overview of Indian logic, with a general introduction followed by specialized sections on four different schools: Nyāya logic, Buddhist logic, Jaina logic, and Navya-Nyāya logic.
Indicative Conditionals
The chapter is an introduction to logical treatments of indicative conditionals, comparing truth-functional, non-truth-functional, and suppositional approaches. Some of the topics discussed are truth conditions, conditional belief, assertability, and issues with compounds of conditionals.
Logic and Natural Language
Logicians have always found inspiration for new research in the ordinary language that is used on a daily basis and acquired naturally in childhood. Whereas the logical issues in the foundations of mathematics motivated the development of mathematical logic with its emphasis on notions of proof, validity, axiomatization, decidability, consistency, and completeness, the logical analysis of natural language motivated the development of philosophical logic with its emphasis on semantic notions of presupposition, entailment, modality, conditionals, and intensionality. The relation between research programs in both mathematical and philosophical logic and natural language syntax and semantics as branches of theoretical linguistics has increased in importance throughout the last fifty years. This chapter reviews the development of one particularly interesting and lively area of interaction between formal logic and linguistics—the semantics of natural language. Research in this emergent field has proved fruitful for the development of empirically, cognitively adequate models of reasoning with partial information, sharing or exchanging information, dynamic interpretation in context, belief revision and other cognitive processes.
Truth
The concept of truth serves in logic not only as an instrument but also as an object of study. Eubulides of Miletus (fl. fourth century BCE), a Megarian logician, discovered the paradox known as ‘the Liar,’ and, ever since his discovery, logicians down the ages – Aristotle and Chrysippus, John Buridan and William Heytesbury, and Alfred Tarski and Saul Kripke, to mention just a few – have tried to understand the puzzling behavior of the concept of truth.
Testimonial Injustice: The Facts of the Matter
To verify the occurrence of a singular instance of testimonial injustice three facts must be established. The first is whether the hearer in fact has an identity prejudice of which she may or may not be aware; the second is whether that prejudice was in fact the cause of the unjustified credibility deficit; and the third is whether there was in fact a credibility deficit in the testimonial exchange. These three elements constitute the facts of the matter of testimonial injustice. In this essay we argue that none of these facts can be established with any degree of confidence, and therefore that testimonial injustice is an undetectable phenomenon in singular instances. Our intention is not to undermine the idea of testimonial injustice, but rather to set limits to what can be justifiably asserted about it. According to our argument, although there are insufficient reasons to identify individual acts of testimonial injustice, it is possible to recognize recurrent patterns of epistemic responses to speakers who belong to specific social groups. General testimonial injustice can thus be characterized as a behavioral tendency of a prejudiced hearer.
Epistemic Injustice: The Power and Ethics of Knowing
Justice is one of the oldest and most central themes of philosophy, but sometimes we would do well to focus instead on injustice. In epistemology, the very idea that there is a first-order ethical dimension to our epistemic practices — the idea that there is such a thing as epistemic justice — remains obscure until we adjust the philosophical lens so that we see through to the negative space that is epistemic injustice. This book argues that there is a distinctively epistemic genus of injustice, in which someone is wronged specifically in their capacity as a knower, wronged therefore in a capacity essential to human value. The book identifies two forms of epistemic injustice: testimonial injustice and hermeneutical injustice. In doing so, it charts the ethical dimension of two fundamental epistemic practices: gaining knowledge by being told and making sense of our social experiences. As the account unfolds, the book travels through a range of philosophical problems. Thus, the book finds an analysis of social power; an account of prejudicial stereotypes; a characterization of two hybrid intellectual-ethical virtues; a revised account of the State of Nature used in genealogical explanations of the concept of knowledge; a discussion of objectification and ‘silencing’; and a framework for a virtue epistemological account of testimony. The book reveals epistemic injustice as a potent yet largely silent dimension of discrimination, analyses the wrong it perpetrates, and constructs two hybrid ethical-intellectual virtues of epistemic justice which aim to forestall it.
Different Voices, Perfect Storms, and Asking Grandma What She Thinks
At first glance it might appear that experimental philosophers and feminist philosophers would make good allies. Nonetheless, experimental philosophy has received criticism from feminist fronts, both for its methodology and for some of its guiding assumptions. Adding to this critical literature, I raise questions concerning the ways in which “differences” in intuitions are employed in experimental philosophy. Specifically, I distinguish between two ways in which differences in intuitions might play a role in philosophical practice, one which puts an end to philosophical conversation and the other which provides impetus for beginning one. Insofar as experimental philosophers are engaged in deploying “differences” in intuitions in the former rather than the latter sense, I argue that their approach is antithetical to feminist projects. Moreover, this is even the case when experimental philosophers deploy “differences” in intuitions along lines of gender.
Different Voices or Perfect Storm: Why are there so few women in philosophy?
Women are significantly underrepresented in philosophy. Although women garner a little more than half of the PhDs awarded in the United States, and about 53 percent of those awarded in the Arts and Humanities, slightly fewer than 30 percent of doctorates in philosophy are awarded to women. And women’s representation in the professoriate falls below that. Why is philosophy so exceptional in this regard? My aim in this paper is not to answer this question but to contrast two different frameworks for addressing it. I call one model “Different Voices” and the other “The Perfect Storm”; I’ll argue that we ought to adopt the secondmodel and that we ought to abandon the first.
Neurodiversity, epistemic injustice, and the good human life
Autism has typically been framed as inherently harmful and at odds with both subjective happiness and objective flourishing. In recent decades, however, the view of autism as inherently harmful has been challenged by neurodiversity proponents, who draw on social and relational models of disability to reframe the harm autistic people face as arising out of the interaction between being autistic and disabling environments. Here we build on the neurodiversity perspective by arguing that autistic thriving has been rendered both invisible and unthinkable by interlocking forms of testimonial and hermeneutical injustice. On the view we propose, rather than autism being at odds with the possibility of living a good life as such, We argue that our mainstream conceptions of the good life have excluded autistic manifestations of happiness and flourishing. This leads to an epistemic catch-22-like paradoxical situation whereby one can be recognised as autistic or as thriving, but not both. We then propose four ameliorative strategies that support moving towards broader conceptions of the good human life which will allow us to recognise not just autistic, but also other neurodivergent ways, of living a good human life.
