Moore Inferences

André Gallois (in The World Without, the Mind Within , Cambridge UP, 1996) maintains that the following schema expresses a warranted form of inference:
p
——————
I believe that p .
I argue that these 'Moore inferences' are not warranted.     

Why Reid was no dogmatist

According to dogmatism, a perceptual experience with p as its content is always a (defeasible) source of justification for the belief that p. Thomas Reid has been an extant source of inspiration for this view. I argue, however, that, though there is a superficial consonance between Reid’s position and that of the dogmatists, their views are, more fundamentally, at variance with one another. While dogmatists take their position to express a necessary epistemic truth, discernible a priori, Reid holds that if something like dogmatism is true, it is a mere contingent truth, discernible a posteriori. Owing to Reid’s epistemological naturalism, it might have been false that a perceptual experience is, by itself, a source of justification. On account of regarding something like dogmatism as only contingently true, then, Reid accepts the demand for a meta-justification of a sort that dogmatists squarely reject, and purports to meet it. Given that dogmatism essentially involves the rejection of the demand to meet this kind of meta-justification, it would seem that Reid should not be construed as endorsing dogmatism at all. I close by briefly considering how Reid’s view fits amongst dogmatism’s competitors.

     

The faculty psychology of Thomas Reid

Contradictory versions of Reid's faculty psychology have been presented. A reexamination of Reid's writings suggests that the term, faculty, was used not as a classificatory device but rather to refer to innate, universal, and active mental powers. Being active, the faculties are one of the basic causes of observable psychological phenomena. The relation of the faculties to other mental powers is considered. A new listing and classification of such powers is compared with that presented in 1936 by H. D. Spoerl which has been used as the basis for much of the subsequent analysis of Reid's faculty psychology.     

Practical Moore Sentences*

I discuss what I call practical Moore sentences: sentences like ‘You must close your door, but I don't know whether you will’, which combine an order together with an avowal of agnosticism about whether the order will be obeyed. I show that practical Moore sentences are generally infelicitous. But this infelicity is surprising: it seems like there should be nothing wrong with giving someone an order while acknowledging that you do not know whether it will obeyed. I suggest that this infelicity points to a striking psychological fact, with potentially broad ramifications concerning the structure of norms of speech acts: namely, when giving an order, we must act as if we believe we will be obeyed.     

Moore on Twin Earth

In a series of articles, Terry Horgan and Mark Timmons have argued that Richard Boyd’s defence of moral realism, utilizing a causal theory of reference, fails. Horgan and Timmons construct a twin Earth-style thought experiment which, they claim, generates intuitions inconsistent with the realist account. In their thought experiment, the use of (allegedly) moral terms at a world is causally regulated by some property distinct from that regulating their use here on Earth; nevertheless, Horgan and Timmons claim, it is intuitive that the inhabitants of this world disagree with us in their moral claims. Since any disagreement would be merely verbal were the alleged moral facts identical to or constituted by different natural facts, the identity or constitution claim must be false. I argue that their argument fails. Horgan and Timmons’ thought experiment is underdescribed; when we fill out the details, I claim, we shall see that the challenge to moral realism fades away. I sketch two possible interpretations of the (apparently) moral claims of the inhabitants of moral Twin Earth. On one interpretation, they fail to disagree with us because they actually agree with us; on the other, they fail to disagree with us because they are not moralizers at all. Which interpretation is true, I argue, will depend on the facts that explain the differences between us and the inhabitants of moral twin Earth.
