In this paper Galileo’s we seek to follow Galileo’s mind as he constructs the principle of the complete isochronism of the pendulum from experimental observations and theoretical demonstrations. Our conclusion will be that the principle came from experiments with relatively small angle pendulums, coupled with a „leap“ from free fall along circular chords and ideas about the natural frequencies of physical systems. The pendulum experiments of the First and Fourth Day were, in all probability, never performed. The results claimes were (...) simply illustrations of the isochronism principle. (shrink)

In a recent paper in this journal which was part of a panel discussion of Grünbaum's philosophy of science, M. G. Evans discusses the Lorentz-Fitzgerald contraction hypothesis and related matters [2]. The purpose of this note is to clarify and correct some of the points in Evans' paper.

I call the activity of assessing and developing improvements of our representational devices ‘conceptual engineering’.¹ The aim of this chapter is to present an argument for why conceptual engineering is important for all parts of philosophy (and, more generally, all inquiry). Section I of the chapter provides some background and defines key terms. Section II presents the argument. Section III responds to seven objections. The replies also serve to develop the argument and clarify what conceptual engineering is.

Herman Cappelen investigates how language and other representational devices can go wrong, and how to fix them. We use language to understand and talk about the world, but what if our language has deficiencies that prevent it from playing that role? How can we revise our concepts, and what are the limits on revision?

The standard view of philosophical methodology is that philosophers rely on intuitions as evidence. Herman Cappelen argues that this claim is false: it is not true that philosophers rely extensively on intuitions as evidence. At worst, analytic philosophers are guilty of engaging in somewhat irresponsible use of 'intuition'-vocabulary. While this irresponsibility has had little effect on first order philosophy, it has fundamentally misled meta-philosophers: it has encouraged meta-philosophical pseudo-problems and misleading pictures of what philosophy is.

One central purpose of Experimental Philosophy (hereafter, x-phi) is to criticize the alleged reliance on intuitions in contemporary philosophy. In my book Philosophy without Intuitions (hereafter, PWI), I argue that philosophers don’t rely on intuitions. If those arguments are good, experimental philosophy has been engaged in an attack on a strawman. The goal of this paper is to bolster the criticism of x-phi in the light of responses.

Cappelen and Hawthorne present a powerful critique of fashionable relativist accounts of truth, and the foundational ideas in semantics on which the new relativism draws. They argue compellingly that the contents of thought and talk are propositions that instantiate the fundamental monadic properties of truth and falsity.

_Insensitive Semantics_ is an overview of and contribution to the debates about how to accommodate context sensitivity within a theory of human communication, investigating the effects of context on communicative interaction and, as a corollary, what a context of utterance is and what it is to be in one. Provides detailed and wide-ranging overviews of the central positions and arguments surrounding contextualism Addresses broad and varied aspects of the distinction between the semantic and non-semantic content of language Defends a distinctive (...) and explanatorily powerful combination of semantic minimalism and speech act pluralism Confronts core problems which not only run to the heart of philosophy of language and linguistics, but which arise in epistemology, metaphysics, and moral philosophy as well.

The beginning of the twenty-first century saw something of a comeback for relativism within analytical philosophy. Relativism and Monadic Truth has three main goals. First, we wished to clarify what we take to be the key moving parts in the intellectual machinations of self-described relativists. Secondly, we aimed to expose fundamental flaws in those argumentative strategies that drive the pro-relativist movement and precursors from which they draw inspiration. Thirdly, we hoped that our polemic would serve as an indirect defence of (...) a traditional and natural picture concerning truth. According to this picture, what we call ‘Simplicity’, the fundamental structure of semantic reality is best revealed by construing truth as a simple monadic property of propositions that serve as the objects of belief, assertion, meaning and agreement. Our project was not a straightforward one. So-called relativists are not uniform in their key ideology, are often sloppy, casual, obscure or confused in their self-characterization, and differ in their argumentative emphasis among themselves and over time, thereby presenting a target that is both amorphous and shifty. This is an area where parties will frequently claim not to understand each other and where certain parties will sometimes accuse others of failing to make any sense at all. In such a situation, any effort to impose order will inevitably strike some parties as tendentious and unfair. That said, we felt that we had enough of …. (shrink)

But the sort of context sensitivity exhibited in such sentences does not compromise the claim that meaning determines truth conditions, since recourse to context here is directed and restricted by conventional meaning alone. Anyone who understands sentence (2) knows that its utterances are true just in case whatever object is demonstrated in the context of utterance is nice; and he also knows that any utterance of (2) says of, or expresses about, whichever object is demonstrated that it’s nice. (Similarly, anyone (...) who understands (3) knows that any utterance of it is true just in case whoever utters it has eaten. And every utterance says of, or expresses about, the speaker that he or she has eaten.) In sum, according to the thesis that meaning determines truth conditions, (indicative) sentences divide into two classes – those with truth conditions tout.. (shrink)

Cappelen and Dever present a forceful challenge to the standard view that perspective, and in particular the perspective of the first person, is a philosophically deep aspect of the world. Their goal is not to show that we need to explain indexical and other perspectival phenomena in different ways, but to show that the entire topic is an illusion.

Bad Language is the first textbook on an emerging area in the study of language: non-idealized language use, the linguistic behaviour of people who exploit language for malign purposes. This lively, accessible introduction offers theoretical frameworks for thinking about such topics as lies and bullshit, slurs and insults, coercion and silencing.

This study – the first full-length monograph in English on the subject – discusses the genesis of Theodor Lessing’s philosophy of history as mainly expressed in his books _Geschichte als Sinngebung des Sinnlosen_ (1919 and 1927), as well as its philosophical implications.

We give a precis of our book Insensitive Semantics.

”Meaningful human control” is a term invented in the political and legal debate on autonomous weapons system, but it is nowadays also used in many other contexts. It is supposed to specify conditions under which an artificial system is under the right kind of control to avoid responsibility gaps: that is, situations in which no moral agent is responsible. Santoni de Sio and Van den Hoven have recently suggested a framework that can be used by system designers to operationalize this (...) kind of control. It is the purpose of this paper to facilitate further operationalization of ”meaningful human control”. -/- This paper consists of two parts. In the first part I resolve an ambiguity that plagues current operationalizations of MHC. One of the design conditions says that the system should track the reasons of the relevant agents. This condition is ambiguous between the kind of reasons involved. On one interpretation it says that a system should track motivating reasons, while it is concerned with normative reasons on the other. Current participants in the debate interpret the framework as being concerned with (something in the vicinity of) motivating reasons. I argue against this interpretation by showing that meaningful human control requires that a system tracks normative reasons. Moreover, I maintain that an operationalization of meaningful human control that fails to track the right kind of reasons is morally problematic.When this is properly understood, it can be shown that the framework of MHC is committed to the agent-relativity of reasons. More precisely, I argue in the second part of this paper that if the tracking condition of MHC plays an important role in responsibility attribution (as the proponents of the view maintain), then the framework is incompatible with first-order normative theories that hold that normative reasons are agent-neutral (such as many versions of consequentialism). In the final section I present three ways forward for the proponent of MHC as reason-responsiveness. (shrink)

In this Introduction, we aim to introduce the reader to the basic topic of this book. As part of this, we explain why we are using two different expressions (‘conceptual engineering’ and ‘conceptual ethics’) to describe the topics in the book. We then turn to some of the central foundational issues that arise for conceptual engineering and conceptual ethics, and finally we outline various views one might have about their role in philosophy and inquiry more generally.

Contemporary society needs the recognition of a moral middle ground, where human behavior can be evaluated as permissible, understandable, or even valuable. As a counterforce to polarization and divisive politics, an identity model is proposed in which individual and group identities are transcended by a human and ecological identity.

There’s an interesting debate in moral and political philosophy about the nature of, and relationship between, ideal and non-ideal theory. In this paper we discuss whether an analogous distinction can be drawn in philosophy of language. Our conclusion is negative: Even if you think that distinction can be put to work within moral and political philosophy, there’s no useful way to extend it to work that has been done in the philosophy of language.

The view defended in this paper - I call it the No-Assertion view - rejects the assumption that it is theoretically useful to single out a subset of sayings as assertions: (v) Sayings are governed by variable norms, come with variable commitments and have variable causes and effects. What philosophers have tried to capture by the term 'assertion' is largely a philosophers' invention. It fails to pick out an act-type that we engage in and it is not a category we (...) need in order to explain any significant component of our linguistic practice. Timothy Williamson (2000) defends a theory of type (i). He says that a theory of assertion has as its goal "[…] that of articulating for the first time the rules of a traditional game that we play" (p. 240). Among those who think we play the game of assertion, there's disagreement about what the rules are. Some think it's a single rule and disagree about what that rule is. Others think the rules change across contexts. According to the No-Assertion view we don’t play the assertion game. The game might exist as an abstract object, but it is not a game you need to learn and play to become a speaker of a natural language. (shrink)

This is the first book devoted to the question of how language can be used to talk about language. Cappelen and Lepore examine the semantics, the pragmatics, and the syntax of linguistic devices that can be used in this way, and present a new account of our use of quotation in a variety of different contexts.

If we don't know what the words 'democracy' and 'democratic' mean, then we don't know what democracy is. This book defends a radical view: these words mean nothing and should be abandoned. The argument for Abolitionism is simple: those terms are defective (...) and we can easily do better, so let's get rid of them. According to the abolitionist, the switch to alternative devices would be a significant communicative, cognitive, and political advance. The first part of the book presents a general theory of abandonment: the conditions under which language should be abandoned. The rest of the book applies this general theory to the case of 'democracy' and 'democratic'. Cappelen shows that 'democracy' and 'democratic' are semantically, pragmatically, and communicatively defective. Abolitionism is not all gloom and doom. It also contains a message of good cheer: we have easy access to conceptual devices that are more effective than 'democracy'. We can do better. These alternative linguistic devices will enable us to ask better questions, provide genuinely fruitful answers, and have more rational discussions. Moreover, those questions and answers better articulate the communicative and cognitive aims of those who use empty terms like 'democracy' and 'democratic'. (shrink)

Can humans and artificial intelligences share concepts and communicate? Making AI Intelligible shows that philosophical work on the metaphysics of meaning can help answer these questions. Herman Cappelen and Josh Dever use the externalist tradition in philosophy to create models of how AIs and humans can understand each other. In doing so, they illustrate ways in which that philosophical tradition can be improved. 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 (for example, creditworthiness, recidivism, cancer, and combatants). If AIs can share our concepts, that will go some way towards justifying this reliance on AI. This ground-breaking study offers insight into how to take some first steps towards achieving Interpretable AI. (shrink)
