Action, Intention and Knowledge Action, Intention and Knowledge Lucy Campbell Homerton College, Cambridge June 2015 This dissertation is submitted for the degree of Doctor of Philosophy. Acknowledgements For financial support throughout my PhD I would like to thank the University of Cambridge, the Cambridge Philosophy Faculty and an anonymous donor without whose generosity this Thesis would almost certainly not have been completed. I would also like to thank my college, Homerton, who have made money available for me to attend conferences and other academic meetings away from Cambridge; this has been a great help. Parts of the work in this Thesis, and their antecedents, have been presented in Oxford, Cambridge and King’s College London, and I am indebted to audiences in each of these places for their time and attention and the helpful discussions which ensued. I would also like to thank the members of a reading group on action which was held in the Cambridge Philosophy Faculty during 2013, and in particular the stalwarts; Arif Ahmed, Jonathan Birch, Ali Boyle, Alexander Greenberg, Jane Heal and Thomas Land. Thanks also go to the King’s College London Philosophy Faculty for preparing me for the PhD, in particular to M.M. McCabe, to Shalom Lappin and to Mark Textor. For some excellent philosophical conversations, both recent and historical, about issues considered in the Thesis but also other interesting things, I thank Maria Alvarez, Luke Brunning, Mike Campbell, Katherine Cecil, Harry Cook, Chris Cowie, Ryan Cox, Tim Crane, Alex Davies, Fee Doherty, Alison Fernandes, Alexander Greenberg, Nathan Hauthaler, Ben Jeffery, John Maier, M.M. McCabe, Rory O’Connell, Nikita Perepelov, Emily Platten, “The Peters” Ridley and Sutton, Lukas Skiba, Henry Tyrrell, Ellisif Wasmuth, Jen Wright and John D. Wright. Chris Cowie, Ryan Cox, Tim Crane, Alison Fernandes, Alexander Greenberg and John Maier deserve particular thanks for reading and commenting on previous incarnations of various parts of the Thesis. I am very lucky to have been supervised from October 2011 by Jane Heal, and from October 2013 by Richard Holton. My meetings with Jane and Richard have been both enjoyable and incredibly useful, and the help they have given me far outstretches what I have been able to indicate in the occasional footnote. Jane in particular, who has supervised me throughout my entire PhD, has given me an extraordinary amount of her time, often meeting me once-weekly for months-long stretches. I am particularly indebted to Jane for keeping me on as a supervisee long after her retirement in 2012. She has read and re-read (and re-re-read) several drafts of each chapter as well as several other pieces, remaining at once encouraging and rigorously critical. And she has been a great help during those times when work wasn’t going so well and I was in low spirits. Her kindness, understanding and patience have been as important to my finishing this Thesis as has her excellent supervision. For friendship, fun and moral support, I would like to thank all of my friends, but especially those, old and new, who I have been lucky enough to have been in contact with not-too-seldom over the past four years; Dan Brigham, Chris Cowie, Julia Felder, Alexander Greenberg, Mynn Khine, M.M. McCabe, Peter Ridley, Jenni Sidey, Lukas Skiba, Henry Tyrrell, Isobel Urquhart, Ellisif Wasmuth and Mike Withey, and amongst those, to Alexander, Chris, Julia, Ellisif and Jenni in particular for so often keeping me company in the pub and occasionally elsewhere. Thanks to my parents for their ongoing support, and most of all to Alexander Greenberg, who has kept me as close to sane as is reasonable to hope for.

The Thesis to be advanced: Non-Propositionalist Intentionalism This Thesis recommends a way of thinking about the knowledge we have of our own intentional actions or, as I will call it, practical knowledge. On this view, one’s knowledge of what one intentionally does is constituted by the intention involved in doing it, on the condition that the intention is executed. Intentions are understood as differing from beliefs both normatively and semantically. They differ normatively in that they set standards on how things are to go or to be going, whereas beliefs have standards set for them by how things are, were or will be. And they differ semantically because whereas beliefs are propositional attitudes, intentions are not, or at least are not fundamentally so. I call this view Non-Propositionalist Intentionalism about Practical Knowledge, or Non- Propositionalist Intentionalism – NPI – for short. The ‘Intentionalism’ part of the name indicates a view on which practical knowledge is constituted by intention, and the Non- Propositionalist part indicates that intentions are here understood as – unlike beliefs – not propositional attitudes. NPI is a response to the problems I find in various attempts to understand how practical knowledge could be constituted by a true belief held in epistemically favourable circumstances, and is a development of the view I find in Anscombe’s Intention. In addition to its key claim - that practical knowledge is constituted by intentions, on the condition that they are executed - NPI involves two other commitments, one epistemological and one action-theoretic. The first is a commitment to understanding knowledge per se as neutral between its practical and theoretical manifestations, as a certain kind of mental engagement with a fact; a kind apt to underwrite certain specifically epistemic capacities, such as the capacity to express and to make inferences from what one knows. Possessing these capacities can be a matter of having a belief which is true and held in epistemically favourable circumstances, but it can also be a matter of having an intention which is being or will be executed. Knowledge manifested in the first way is ‘theoretical’ and knowledge manifested in the second way is ‘practical’. The second commitment is to a non-reductive conception of the relationship between the phenomena (concepts) of practical knowledge, intentional action and intention-execution. These three phenomena are understood as three distinct yet essentially related facets of a single underlying phenomenon. The concepts which pick out each of these three facets are to be conceptually elucidated in terms of one another. Thinking of someone as φ-ing intentionally, as executing their intention to φ, or as having practical knowledge that they are φ-ing is thinking of them as instantiating a single phenomenon under three different aspects. I argue that NPI is the best way to jointly meet several constraints on a good account of practical knowledge, which will be introduced and explained throughout the Thesis. i b. The structure of the discussion The Thesis falls into three parts; NPI is introduced and defended in Part Three. Let me sketch the argumentative route which will take us there. Part One introduces our target phenomenon - practical knowledge - and motivates accepting some version of Intentionalism; the view that practical knowledge is somehow constituted by the agent’s intention.

This response assumes something about us: that we have free and determinism will. against compatibilist free will But what does this mean? against incompatibilist free will To say that we have to free will is to say that some of our actions are up to us; it to say that, at least sometimes, we have the ability to choose what we do. Is it true that some of our actions are up to us, and that we sometimes are able to choose what we will do? This is the question we’ll be asking ourselves for the next two weeks. Our discussion will involve us considering the three strongest arguments against the view that we have free will. But before doing that it is worth asking why there is any reason to accept the common view that we do have free will. Are there any arguments in favor of the reality of free will? view that we have free will. the case for free will But before doing that it is worth asking why there is any reason to accept the common view that we do have free will. Are there any free will and determinism arguments in favor of the reality of free will? against compatibilist free will There are. The first argument starts with an apparent fact about moral against responsibility: it seems (at least to a first approximation) that we are incompatibilist free will only responsible for actions which we freely perform.

  • PRAGMATISM AS a PHILOSOPHY of ACTION (Paper Presented at the First Nordic Pragmatism Conference, Helsinki, Finland, June 2008)
    1 PRAGMATISM AS A PHILOSOPHY OF ACTION (Paper presented at the First Nordic Pragmatism Conference, Helsinki, Finland, June 2008) Erkki Kilpinen University of Helsinki When I gave the doctrine of pragmatism the name it bears, – and a doctrine of vital significance it is, – I derived the name by which I christened it from pragma, – behaviour – in order that it should be understood that the doctrine is that the only real significance of a general term lies in the general behaviour which it implies. Charles S. Peirce, May 1912 cited by Eisele (1987:95).1 Introduction: Action ahead of knowledge on pragmatism’s philosophical agenda Although the very founder of the pragmatic movement is adamant that this philosophy is inherently related to action – or behaviour as Peirce laconically says here – philosophers have been curiously reluctant to recognize this. Of course one finds in the literature comments about how pragmatists often talk about action, and some commentators feel that they talk about it too often, at the expense of traditional philosophical problems. To see this is not yet, however, to see the essential pragmatist point; in what sense they talk about action. Their usage of this term and the underlying idea differ from what is customary in other philosophical approaches. Pragmatism namely approaches all theoretical and philosophical problems as problems that in final analysis are related to action. In mainstream philosophy, both in its positivist-analytic and phenomenological versions, action is a contingent empirical phenomenon demanding an explanation. In pragmatism, action is a universal phenomenon which in itself begs no explanation but rather makes the starting point for explanations.

  • An Interview with Donald Davidson
    An interview with Donald Davidson Donald Davidson is an analytic philosopher in the tradition of Wittgenstein and Quine, and his formulations of action, truth and communicative interaction have generated considerable debate in philosophical circles around the world. The following "interview" actually took place over two continents and several years. It's merely a part of what must now be literally hundreds of hours of taped conversations between Professor Davidson and myself. I hope that what follows will give you a flavor of Donald Davidson, the person, as well as the philosopher. I begin with some of the first tapes he and I made, beginning in Venice, spring of 1988, continuing in San Marino, in spring of 1990, and in St Louis, in winter of 1991, concerning his induction into academia. With some insight into how Professor Davidson came to the profession, a reader might look anew at some of his philosophical writings; as well as get a sense of how the careerism unfortunately so integral to academic life today was so alien to the generation of philosophers Davidson is a member of. The very last part of this interview is from more recent tapes and represents Professor Davidson's effort to try to make his philosophical ideas available to a more general audience. Lepore: Tell me a bit about the early days. Davidson: I was born in Springfield, Massachusetts, on March 6, 1917 to Clarence ("Davie") Herbert Davidson and Grace Cordelia Anthony. My mother's father's name was "Anthony" but her mother had married twice and by coincidence both her husbands were named "Anthony".

  • Philosophy of Action and Theory of Narrative1
    PHILOSOPHY OF ACTION AND THEORY OF NARRATIVE1 TEUN A. VAN DIJK 1. INTRODUCTION 1.1. The aim of this paper is to apply some recent results from the philosophy of action in the theory of narrative. The intuitive idea is that narrative discourse may be conceived of as a form of natural action description, whereas a philosophy or, more specifically, a logic of action attempts to provide formal action descriptions. It is expected that, on the one hand, narrative discourse is an interesting empirical testing ground for the theory of action, and that, on the other hand, formal action description may yield insight into the abstract structures of narratives in natural language. It is the latter aspect of this interdisciplinary inquiry which will be em- phasized in this paper. 1.2. If there is one branch of analytical philosophy which has received particular at- tention in the last ten years it certainly is the philosophy of action. Issued from classical discussions in philosophical psychology (Hobbes, Hume) the present analy- sis of action finds applications in the foundations of the social sciences, 2 in ethics 3 1This paper has issued from a seminar held at the University of Amsterdam in early 1974. Some of the ideas developed in it have been discussed in lectures given at the Ecole Pratique des Hautes Etudes (Paris), Louvain, Bielefeld, Münster, Ann Arbor, CUNY (New York) and Ant- werp, in 1973 and 1974. A shorter version of this paper has been published as Action, Action Description and Narrative in New literary history 6 (1975): 273-294.

First of all I would like to thank my supervisor and promotor Lodi Nauta for his comments on an enormous variety of drafts and for the many stimulating discussions we had throughout the project. He did not limit himself to deeply theoretical discussions but also saved me from grammatical and stylish sloppiness. (He would, for example, have suggested to leave out the ‘enormous’ and ‘many’ above, as well as by far most of the ‘very’’s and ‘greatly’’s in the sentences to come.) After I had already started my new job outside the academic world, Lodi regularly – but always in a pleasant way – reminded me of this other job that still had to be finished.

  • Introduction to Philosophy of Action Harry Alanen Harry.Alanen
    Introduction to Philosophy of Action Harry Alanen [email protected] These lectures aim to give students an overview of the central problems and positions in the philosophy of action. More specifically, the aim will be to help students raise critical questions regarding what actions are, and how actions are to be explained, by considering what different theories of action try to achieve. The lectures are aimed at undergraduates intending to take finals in Philosophy of Mind or Ethics, but those taking Philosophy of Social Sciences or Cognitive Science may also find the lectures helpful overviews of the problems relating to the explanation of action. Graduate students interested in an overview of key positions and developments in philosophy of action are also encouraged to attend. Each lecture will be followed by an optional Q&A session. A reading list will be provided before the lectures start. Lecture 1 (Week 5). The problem of explaining human behaviour. This lecture raises a number of preliminary questions and problems regarding action and agency, such as: how is human behaviour and action best explained? Are the best explanations of actions scientific explanations? If so, what does this mean for our own understanding of our actions and reasons? In connection to these questions the lecture will consider a type causal explanation called the 'covering law'-model of explanation, developed e.g. by Carl Hempel, according to which causes and effects are connected by a law of nature. Lecture will 2 raise a problem for this kind of causal explanation, and Lecture 3 will consider alternative causal accounts.

  • Donald Davidson ERNEST LEPORE and KIRK LUDWIG
    Midwest Studies in Philosophy, XXVIII (2004) Donald Davidson ERNEST LEPORE AND KIRK LUDWIG avidson, Donald (Herbert) (b. 1917, d. 2003; American), Willis S. and Marion DSlusser Professor, University of California at Berkeley (1986–2003). Previ- ously Instructor then Professor in Philosophy at: Queens College New York (1947–1950), Stanford University, California (1950–1967), Princeton University (1967–1969), Rockefeller University, New York City (1970–1976), University of Chicago (1976–1981), University of California at Berkeley (1981–2003). John Locke Lecturer, University of Oxford (1970). One of the most important philosophers of the latter half of the twentieth century, Donald Davidson explored a wide range of fundamental topics in meta- physics, epistemology, ethics, and the philosophies of action, mind, and language. His impact on contemporary philosophy is second only to that of his teacher W. V. O. Quine, who, along with Alfred Tarski, exerted the greatest influence on him. Given the range of his contributions, his work emerges as surprisingly systematic, an expression and working out of a number of central guiding ideas. Among his most important contributions are 1. his defense of the common sense view that reasons, those beliefs and desires we cite in explaining our actions, are also causes of them [11], 2. his groundbreaking work in the theory of meaning, and his proposal, based on Tarski’s work on recursive truth definitions for formal languages, for how to formulate a compositional semantic theory for a natural language [29, 46, 47, 50, 51], 3. his development of the project of radical interpretation as a vehicle for investigating questions about meaning and the psychological attitudes involved in understanding action [7, 15, 42, 44, 48], 309 310 Ernest Lepore and Kirk Ludwig 4.

    Philosophers’ , . you are oered a large sum of money to intend on I mprint Tuesday to drink toxin on Wednesday. The toxin will make you ill if you drink it, but you only have to intend to drink it in O order to receive the money.Obviously, it is desirable for you to intend to drink the toxin, yet this fact seems incapable of moving you to so intend. Why is this so? Does your inability to win the money reflect a flaw in your rationality? How Action Michael Bratman has pointed out that when one deliberates about the future, one’s focus is on what to do in the future, not on what to in- tend now, although a judgment about what to do later does lead to an intention now about what to do later (, ). Understanding why Governs Intention this is so is the key to solving the toxin puzzle. õ 0RACTICALõDELIBERATION Before looking for an explanation of the phenomenon that Bratman describes, we need a more precise characterization of it. First of all, it is not true that any deliberation we engage in about the future is about what to do in the future; we also deliberate about what will be the case in the future. This latter kind of deliberation concludes in a future-di- rected belief rather than a future-directed intention. I will call delibera- tion that concludes in a belief doxastic deliberation and deliberation that concludes in an intention practical deliberation. Bratman’s claim, then, is about practical deliberation: deliberation that concludes in an intention now for later is about what to do in the future.
