Drawing upon research in philosophical logic, linguistics and cognitive science, this study explores how our ability to use and understand language depends upon our capacity to keep track of complex features of the contexts in which we converse.

Philosophers frequently struggle with the relation of metaphysics to the everyday world, with its practical value, and with its relation to empirical science. This paper distinguishes several different models of the relation between philosophical ontology and applied (scientific) ontology that have been advanced in the history of philosopy. Adoption of a strong participation model for the philosophical ontologist in science is urged, and requirements and consequences of the participation model are explored. This approach provides both a principled view and justification of the role of the philosophical ontologist in contemporary empirical science as well as guidelines for integrating philosophers and philosophical contributions into the practice of science.

In this paper I do two things: (1) I support the claim that there is still some confusion about just what the Quine-Putnam indispensability argument is and the way it employs Quinean meta-ontology and (2) I try to dispel some of this confusion by presenting the argument in a way which reveals its important meta-ontological features, and include these features explicitly as premises. As a means to these ends, I compare Peter van Inwagen’s argument for the existence of properties with Putnam’s presentation of the indispensability argument. Van Inwagen’s argument is a classic exercise in Quinean meta-ontology and yet he claims – despite his argument’s conspicuous similarities to the Quine-Putnam argument – that his own has a substantially different form. I argue, however, that there is no such difference between these two arguments even at a very high level of specificity; I show that there is a detailed generic indispensability argument that captures the single form of both. The arguments are identical in every way except for the kind of objects they argue for – an irrelevant difference for my purposes. Furthermore, Putnam’s and van Inwagen’s presentations make an assumption that is often mistakenly taken to be an important feature of the Quine-Putnam argument. Yet this assumption is only the implicit backdrop against which the argument is typically presented. This last point is brought into sharper relief by the fact that van Inwagen’s list of the four nominalistic responses to his argument is too short. His list is missing an important – and historically popular – fifth option.

This paper compares and contrasts three views on the issue of 'solipsism' that were much discussed in the first half of the 20th century, namely those of Wittgenstein, Carnap and Reichenbach. While the paper deals mainly with early Wittgenstein, the so-called 'later Wittgenstein' is seen as arguing that Carnap's Aufbau, and any similar 'solipsist' reinterpretation of the language must start with a notion of experience utterly different from the one we actually have. And this criticism actually coheres with Wittgenstein's views in the Tractatus.

1. Abstract: In this paper I discuss Putnam’s view on time and the special theory of relativity. I first locate Putnam’s philosophical approach within a more general framework, essentially making reference to Sellar’s distinction between the scientific image and the manifest image of the world. I then reconstruct Putnam’s argument in favour of the reality of the future and the determinateness of truth-value for future tense sentences (Putnam 1967) by showing that it is based on three premises that generate a contradiction. In the second part of the paper I discuss Putnam’s argument both by using later results belonging to the foundations of STR and quantum mechanics (Putnam 2005), and by invoking some conceptual analysis on the pseudo-predicate “is real”. Since I will show that the presentists/eternalists debate is ill-founded if regarded as ontological, I will conclude that it boils down to our different practical attitudes towards past, present and future.

Engaging, accessible, and up-to-date, this work introduces the central debates of English language philosophy since 1945. It begins with a brief description of philosophical debate during the first half of the twentieth century, offering fascinating discussions of writings by Wittgenstein, Ryle, Austin, Quine, and Sellars. It then describes several ensuing philosophical debates that have shaped philosophical discussions since the 1960s, addressing the Davidson/Dummett debate on language; the Kripke/Lewis debate on possible worlds; the Popper/Kuhn debate on the justification in epistemology; the debates on materialism, functionalism, and dual-aspect theories of mind; and recent work in moral psychology, metaethics, and normative ethics. It also includes a critical discussion of Rorty's metaphilosophical skepticism and pays extensive attention to writings of Strawson, Putnam, Evans, McDowell, Williams, Nagel, and many other contemporary philosophers.

In this brief book one of the most distinguished living American philosophers takes up the question of whether ethical judgments can properly be considered ...

In this detailed study, Christopher Norris defends the kinds of arguments advanced by the early realist, Hilary Putnam. Norris makes a point of placing Putnam's work in a wider philosophical context, and relating it to various current debates in epistemology and philosophy of science. Much like Putnam, Norris is willing to take full account of opposed viewpoints while maintaining a vigorously argued commitment to the values of debate and enquiry.

One of the most influential contemporary philosophers, Hilary Putnam's involvement in philosophy spans philosophy of mind, philosophy of language, ontology and epistemology and logic. This edited volume explores Putnam's contribution to the contemporary realist and pragmatist debate and includes Putnam's comments on each issue raised.

In this paper, I will discuss, and to some extent criticize, Hilary Putnam’s views on ontology, recently summarized and defended in his Ethics without Ontology (2004). I will start out with a critical discussion of Putnam’s thesis of conceptual relativity. Then I will turn to what is the main issue in the book: the criticism of the focus on ontological matters in philosophical discussions of mathematics and ethics.
