I have developed transcendental arguments to refute several versions of Nick Bostrom’s simulation hypothesis. I called some of these arguments the SIM-style argument. In this paper, I have four main aims. First, I employ the SIM-style argument to remedy a defect in Hilary Putnam’s Brain-in-vat argument. Second, I show that the most radical skepticism, which Tim Button called the nightmarish Cartesian skepticism, can be refuted by the SIM-style argument or by another transcendental argument I develop here. Third, I compare (...) my approach to radical skepticisms with Donald Davidson’s, as it is often regarded as an exemplar of transcendental arguments. Fourth, I explain how the prominent objections, mainly developed by Barry Stroud, to transcendental arguments can incur two undesirable results: psychologism and Kantian skepticism. (shrink)

Putnam's goal is to embed philosophy in social life. The first part of this book is dedicated to metaphysical questions.

In this book, one of the world's preeminent philosophers takes issue with an idea that has found an all-too-prominent place in popular culture and philosophical ...

It is widely recognized that ‘global’ symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-ship phenomenon. However, conventional wisdom holds that ‘local’ symmetries, such as the diffeomorphism invariance of general relativity and the gauge invariance of classical electromagnetism, have no such direct empirical counterparts. We argue against this conventional wisdom. We develop a framework for analysing the relationship between Galileo-ship empirical phenomena on the one hand, and (...) physical theories that model such phenomena on the other, that renders the relationship between theoretical and empirical symmetries transparent, and from which it follows that both global and local symmetries can give rise to Galileo-ship phenomena. In particular, we use this framework to exhibit an analogue of Galileo’s ship for the local gauge invariance of electromagnetism. 1 Introduction2 Analogues of Galileo’s Ship?

It is a relatively rare, and very welcome, event when an original, brilliantly imaginative analytic philosopher takes a fresh look at earlier figures in the history of philosophy and proceeds to tell a story that ties in their work with his own. Analytic philosophy’s greatest disability remains its lack of historical resonance, and Hilary Putnam is one of the few who have worked hard to help it overcome this handicap. His discussion of the great American pragmatists has made it (...) possible for students to see past the dismissive attitudes that Russell and Ayer, for example, adopted toward James and Dewey. Advancing along lines sketched out some decades ago in Morton White’s prescient Toward Reunion in Philosophy, Putnam has helped us see in detail how Quinean skepticism about the language-fact and essence-accident dualisms ties in with James’s and Dewey’s skepticism about many other traditional dualisms.

The present paper is an attempt to give an account of the analytic-synthetic distinction both inside and outside of physical theory. It is hoped that the paper is sufficiently nontechnical to be followed by a reader whose background in science is not extensive; but it has been necessary to consider problems connected with physical science (particularly the definition of 'kinetic energy,' and the conceptual problems connected with geometry) in order to bring out features of the analytic-synthetic distinction that seem to (...) me to be the most important.

In July 2018, the Nuffield Council of Bioethics released its long-awaited report on heritable genome editing. The Nuffield report was notable for finding that HGE could be morally permissible, even in cases of human enhancement. In this paper, we summarise the findings of the Nuffield Council report, critically examine the guiding principles they endorse and suggest ways in which the guiding principles could be strengthened. While we support the approach taken by the Nuffield Council, we argue that detailed consideration of (...) the moral implications of genome editing yields much stronger conclusions than they draw. Rather than being merely ‘morally permissible’, many instances of genome editing will be moral imperatives. (shrink)

SummaryI discuss a simple case in which theories with different ontologies appear equally adequate in every way. . I contend that the appearance of equal adequacy is correct, and that what this shows is that the notion of “existence” has a variety of different but legitimate uses. I also argue that this provides a counterexample to the claim advanced by Davidson, that conceptual relativity is incoherent.RésuméJe discute un cas simple où des théories comportant des ontologies différentes apparaissent également adéquates à (...) tout point de vue. .

In this lecture I describe the path by which I was led to the “semantic externalism” for which I was honoured with the Rolf Schock Prize. Although my interest in linguistics goes back as far as my undergraduate days, it was conversations with Jerrold Katz and Jerry Fodor at MIT (where all three of us taught at the time) in the 1960s that first led to an effort by all three of us to develop semantic theories. My own direction was (...) a false one, by my present lights; at that time all three of us defended the “internalist” view that the meaning of a word is fixed by a “battery of semantical rules” implicitly known by each speaker. I describe how I was led to the realization that this could not be right, and finally to the views I defended in “The Meaning of ‘Meaning' ”. (shrink)

The following is a transcript of a discussion about the question between Richard Rorty, Hilary Putnam, and James Conant. The discussion was part of a series of discussions on more or less philosophical subjects broadcast on Chicago Public Radio. This discussion is anchored by Gretchen Helfrich. Two listeners (Chris and Edwin) also took part.

This paper responds to Stroud's important The Significance of Philosophical Scepticism. The author defends a view in which statements in a natural language have truth-evaluable content only in concrete contexts. It is argued that just what counts as a concrete possibility that must be defeated before one can say that one knows something is a highly context-sensitive matter, and that Stroud's alternative to this context-sensitive account of the way the verb "know" functions seems to be either a semantics in which (...) knowledge claims (about the "external world") are trivially logically false or no intelligible semantics at all.

This essay argues that African palaver ethics makes a vital contribution to the common good tradition in Catholic social ethics. It highlights the significance of solidarity in both Bénézet Bujo’s account of palaver ethics and David Hollenbach’s account of the common good. Yet it concedes that palaver ethics is not perfect as it does not adequately address the missing voices of women. Therefore, it calls for the ethical conversion of the palaver so as to duly recognize the voices of African (...) women and their various contributions to the common good. (shrink)

There are old and convincing arguments for intellectual liberty in all of its forms — freedom to think, to speak, to publish — based on assumptions that we who have been brought up in Western democratic countries take for granted. Two major arguments are particularly powerful. The first I shall call the Utilitarian argument which, in its simplest form, says that without intellectual liberty any Party and any government will harden into an exploiting class, a tyranny. The Kantian argument is (...) that, quite apart from its value to society, intellectual liberty — Kant calls it autonomy — is absolutely indispensable to the integrity of the person. In this paper I defend the Kantian approach. The philosophical-epistemological question "How do you know autonomy is a good thing?" remains unanswered. No further foundation can be given. (shrink)

I cannot claim to be an “Analytical Thomist” for two reasons: first, I am a practicing Jew, and Thomism is a philosophical tradition within the Roman Catholic Church. But not only do I philosophize within a different religious tradition than Thomists do, there is also the fact that my own approach to philosophy is, I think, quite different. My purpose here, however, is not to reject Analytical Thomism, or even to criticize it, but rather to enter into a dialogue with (...) it. Thus, even if I do not put the remarks that follow in the form of questions, they are intended in a sense as a set of questions addressed to those who do consider themselves to be Analytical Thomists.

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

First published in 1971, Professor Putnam's essay concerns itself with the ontological problem in the philosophy of logic and mathematics - that is, the issue of whether the abstract entities spoken of in logic and mathematics really exist. He also deals with the question of whether or not reference to these abstract entities is really indispensible in logic and whether it is necessary in physical science in general.

First published in 1978, this reissue presents a seminal philosophical work by professor Putnam, in which he puts forward a conception of knowledge which makes ethics, practical knowledge and non-mathematic parts of the social sciences just as much parts of 'knowledge' as the sciences themselves. He also rejects the idea that knowledge can be demarcated from non-knowledge by the fact that the former alone adheres to 'the scientific method'. The first part of the book consists of Professor Putnam's John Locke (...) lectures, delivered at the University of Oxford in 1976, offering a detailed examination of a 'physicalist' theory of reference against a background of the works of Tarski, Carnap, Popper, Hempel and Kant. The analysis then extends to notions of truth, the character of linguistic enquiry and social scientific enquiry in general, interconnecting with the great metaphysical problem of realism, the nature of language and reference, and the character of ourselves.
