§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)

G.E. Moore’s open question arguments have been targeted by unsympathetic philosophers for close to a century. Perhaps the most serious criticism directed towards Moore’s OQAs is that they be...

In contemporary psychology and philosophy, influential theories approach the emotions via their relations to values and evaluations. My aim is to contribute to our understanding of how these evaluative theories in psychology and philosophy relate to one another. I first explain why this presupposes that we make up our minds about the relations between “molecular” and “molar” properties. The rest of my discussion explores some ways of understanding the relation between the molar and the molecular: as a relation of epistemological (...) support, of identity or of the determinable-determinates type.

Millianism is a thesis in philosophy of language that the meaning of a proper name is simply its referent. Millianism faces certain puzzles called Frege's Puzzles. Some Millians defend the view by appealing to a metaphysics of belief that involves Ways of Believing. In the first part of this paper, I argue that ethical naturalists can adopt this Millian strategy to resist Moore’s Open Question argument. While this strategy of responding to the Open Question Argument has already appeared in the (...) literature, I show that the Millian strategy can be easily extended to other versions of the Open Question Argument that are alleged to be stronger than the original formulation. The allegedly stronger versions of the Open Question Argument are not straightforwardly Frege's Puzzles, but they still have analogue versions that have been presented against Millianism. What the Ways Millian can say against those analogue versions can easily be applied to these other versions of the Open Question Argument. (shrink)

This thesis modifies the wording of William Clifford’s 1877 evidence principle (that ‘it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence’) to propose an explicitly moral principle, restricted to descriptive beliefs (about what is or is not the case) and excluding prescriptive beliefs (about what ought or ought not to be the case). It considers potential counter-examples, particularly William James’s 1896 defence of religious belief; and concludes that the modified principle survives unscathed. It then searches (...) for suitable criteria for ‘sufficient’ and ‘insufficient’ evidence, first within a Bayesian framework enriched by pragmatic considerations, and finally by returning to Clifford’s conception of our shared responsibilities to our shared epistemic asset. Combined with elements of Edward Craig’s (1990, 1999) ‘state-of-nature’ theory of knowledge this gets us to a minimum threshold to avoid insufficient evidence and an aspirational criterion of sufficient evidence.
