A new reading of G.E. Moore's ‘Proof of an External World’ is offered, on which the Proof is understood as a unique and essential part of an anti-sceptical strategy that Moore worked out early in his career and developed in various forms, from 1909 until his death in 1958. I begin by ignoring the Proof and by developing a reading of Moore's broader response to scepticism. The bulk of the article is then devoted to understanding what role the Proof plays (...) in Moore's strategy, and how that role is played. (shrink)

§13 of Principia Ethica contains G. E. Moore’s most famous open question arguments. Several of Moore’s contemporaries defended various forms of metaethical nonnaturalism—a doctrine Moore himself endorsed—by appeal to OQAs. Some contemporary cognitivists embrace the force of Moore’s OQAs against metaethical naturalism. And those who posit noncognitivist meaning components of ethical terms have traditionally used OQAs to fuel their own emotivist, prescriptivist, and expressivist metaethical programs. Despite this influence, Moore’s OQAs have been ridiculed in recent decades. Their deployment has been (...) labeled “accident prone,” “simple to dismiss,” and just plain invalid. Critics accuse Moore of begging the question. Others argue that his OQAs founder upon the paradox of analysis. And still others argue that Moore’s open question argumentation is incompatible with the Kripke–Putnam causal theory of reference and thus it “simply fails; it is bankrupt”. I aim to show that there is something of continuing value in Moore’s open question efforts. I present and criticize Nicholas Sturgeon’s influential interpretation of Moore’s OQAs as a means to motivate and explicate my own interpretation of Moore’s thoughts in §13 of Principia Ethica. I then articulate the role that OQAs are intended to play in Moore’s overall argumentative strategies to undermine metaethical naturalism and thereby provide some theoretical support for metaethical nonnaturalism. Finally, I attend to the most prominent objections to Moore’s theorizing and attempt to evaluate the extent to which Moore’s efforts are successful. My hope is to display both the promising portions of Moore’s metaethical argumentation in Principia Ethica as well as its limitations. (shrink)

Empty proper names give rise to intriguing questions. Frege, Moore and Russell stand at the beginning of analytic philosophy's engagement with these questions. In this paper I will therefore introduce and assess their views on the topic of empty names and draw connections to recent work.

Moral properties would supervene upon non‐moral properties and be conceptually autonomous. That, according to Simon Blackburn, would make them if not impossible at least mysterious, and evidence for them best explained by theorists who say they are not real. In fact moral properties would not challenge in ways Blackburn has contended. There is, however, something new that can be gathered from his arguments. What would the supervenience of moral properties and their conceptual autonomy from at least total non‐moral properties entail (...) not only for Intuitionists, who ‘knew this all along,’ but for all moral realists, that there are synthetic necessary moral principles? There is for all moral realists the problem of explaining ‘what in the world’makes possible these necessities. (shrink)

Identity arguments for the existence of god offer an intriguing blend of conceptual and existential claims. As it happens, this sort of blend has been probed for more than a century in metaethics, ever since G.E. Moore formulated the Open Question Argument against metaethical naturalism. Moore envisaged naturalism as offering identity claims between good and natural properties. His central worry was that such identity claims should render certain questions closed and hence meaningless. However, he contended that speakers competent with the (...) respective concepts would find these questions meaningful, thereby indicating the failure of the identity claim in question, and of all such identity claims. The history of this issue in metaethics provides an important perspective on the prospects of devising cogent, rhetorically successful versions of identity arguments for the existence of god. Both the conceptual and existential premises of such arguments involve conceptual nuances that metaethicists have studied. Overall, the history of the Open Question Argument provides reason to think that rationally compelling versions of identity arguments for the existence of god are very unlikely to be constructed.

The aim of this paper is to argue that what I call the simple theory of introspection can be extended to account for our introspective knowledge of what we believe as well as what we consciously experience. In section one, I present the simple theory of introspection and motivate the extension from experience to belief. In section two, I argue that extending the simple theory provides a solution to Moore’s paradox by explaining why believing Moorean conjunctions always involves some degree (...) of irrationality. In section three, I argue that it also solves the puzzle of transparency by explaining why it’s rational to answer the question whether one believes that p by answering the question whether p. Finally, in section four, I defend the simple theory against objections by arguing that self-knowledge constitutes an ideal of rationality. (shrink)

How does public discussion contribute to the reasonableness with which power is exercised in a democracy? Contemporary answers to this question (such as formulated by Rawls or Habermas), are often based upon two interconnected preconceptions. These are, 1. the idea that the value of public discussion lies primarily in the fact that citizens can reach a reasonable consensus through argumentation and discussion and, 2. the belief that the exercise of power is legitimate only if it is determined by a reasonable (...) consensus among citizens. In this sense, 'reasonable consensus among citizens' eliminates, under ideal conditions, the 'autonomy' of the exercise of power. However, these ideals of democracy appear to conflict with certain aspects of democratic society; aspects, moreover, which we tend to value quite highly. I therefore advance an alternative account of the reasonableness of power in democratic societies; one which acknowledges both the characteristically unlimited scope of public discussion in democratic society and the fact that such discussion rarely or perhaps even never ends in a general consensus. In order to elucidate the democratic character of society we must explain the relationship between discussion and power in such a way that we understand both the need for discussion and the necessity of an autonomous exercise of power.

G.E. Moore noticed the oddity of statements like: “It's raining, but I don't believe it.” This oddity is often seen as analogous to the oddity of believing akratically, or believing what one believes one should not believe, and has been appealed to in denying the possibility of akratic belief. I describe a Belief Akratic's Paradox, analogous to Moore's paradox and centered on sentences such as: “I believe it's raining, but I shouldn't believe it.” I then defend the possibility of akratic (...) belief against appeals to this analogy, arguing both that akratic belief does not require belief-akratic-paradoxical belief, and that the latter is importantly different from Moorean belief. I conclude by considering the implications of these arguments for an understanding of both Moorean and akratic belief. (shrink)
