Bad Language

When theorizing about language, we tend to assume that speakers are cooperative, honest, helpful, and so on. This, of course, isn't remotely true of a lot of real-world language use. Bad Language is the first textbook to explore non-idealized language use, the linguistic behaviour of those who exploit language for malign purposes. Two eminent philosophers of language present a lively and accessible introduction to a wide range of topics including lies and bullshit, slurs and insults, coercion and silencing: Cappelen and Dever offer theoretical frameworks for thinking about these all too common linguistic behaviours. As the text does not assume prior training in philosophy or linguistics, it is ideal for use as part of a philosophy of language course for philosophy students or for linguistics students. Bad Language belongs to the series Contemporary Introductions to Philosophy of Language, in which each book introduces an important area of the philosophy of language, suitable for students at any level.

Can humans and artificial intelligences share concepts and communicate? One aim of Making AI Intelligible is to show that philosophical work on the metaphysics of meaning can help answer these questions. Cappelen and Dever use the externalist tradition in philosophy of to create models of how AIs and humans can understand each other. In doing so, they also show ways in which that philosophical tradition can be improved: our linguistic encounters with AIs revel that our theories of meaning have been excessively anthropocentric. The questions addressed in the book are not only theoretically interesting, but the answers have pressing practical implications. Many important decisions about human life are now influenced by AI. In giving that power to AI, we presuppose that AIs can track features of the world that we care about (e.g. creditworthiness, recidivism, cancer, and combatants.) If AIs can share our concepts, that will go some way towards justifying this reliance on AI. The book can be read as a proposal for how to take some first steps towards achieving interpretable AI. Making AI Intelligible is of interest to both philosophers of language and anyone who follows current events or interacts with AI systems. It illustrates how philosophy can help us understand and improve our interactions with AI.

Philosophical Foundations

Making AI Intelligible

Context and Communication offers an introduction to a central theme in the study of language: the various ways in which what we say (or ask, or think) depends on the context of speech and thought. The period since 1970 has produced a vast literature on this topic, both by philosophers and by linguists. It is one of the areas of philosophy (and linguistics) where most progress has been made over the last few decades. This book explores some of the central data, questions, concepts, and theories of context sensitivity. It is written to be accessible to someone with no prior knowledge of the material or, indeed, any prior knowledge of philosophy, and is ideal for use as part of a philosophy of language course by students of philosophy or linguistics. Context and Communication is the first in the series Contemporary Introductions to Philosophy of Language. Each book in the series provides an introduction to an important topic in philosophy of language. The second volume on reference is currently in preparation. These textbooks can be used as a module in a philosophy of language course, for either undergraduate or graduate students.
