Hilary Putnam has famously undergone some radical changes of mind with regard to the issue of scientific realism and its wider epistemological bearings. In this paper I defend the arguments put forward by early Putnam in his essays on the causal theory of reference as applied to natural-kind terms, despite his own later view that those arguments amounted to a form of 'metaphysical' realism which could not be sustained against various lines of sceptical attack. I discuss some of the reasons (...) for Putnam's retreat, first to the theory of 'internal (or framework-relative) realism proposed in his middle-period writings, and then to a commonsensepragmatist stance which claims to resituate this whole discussion on ground that has not been trorldden into ruts by the contending philosophical schools. In particular I examine his protracted engagement with various forms of anti-realist doctrine (Michael Dummett's most prominent among them), with Wittgenstein's thinking about language-games or meaning-as-use, and with a range of sceptical- relativist positions adopted in the wake of Quine's influential attack on the two last 'dogmas' of logical empiricism. My paper seeks to show that Putnam has been over-impressed by some of the arguments — from these and other sources — which he takes to constitute a knock-down case against the kind of extemalist and causal-realist approach developed in his early essays. It concludes by re-stating that position in summary form and relating it to other, more recent defences of causal realism in epistemology and philosophy of science. (shrink)

It is argued that the debate regarding radical scepticism needs to be conducted in the light of a value-theoretic methodological constraint. It is further shown that such a methodological constraint raises some uncomfortable problems for the main anti-sceptical proposals in the literature.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

Nudging is the idea that people’s decisions and behaviors can be influenced in predictable, non-coercive ways by making small changes to the choice architecture. In this paper, I differentiate between type-1 nudges and type-2 nudges according to the thinking processes involved in each. With this distinction in hand, I present the libertarian paternalistic criteria for the moral permissibility of intentional nudges. Having done this, I motivate an objection to type-1 nudges. According to this objection, type-1 nudges do not appear to (...) be relevantly different than standard cases of manipulation, and manipulation is morally problematic. While I show that this objection fails, I argue that its evaluation raises a different challenge for Libertarian Paternalism. The libertarian paternalistic criteria fails because it ignores the moral distinction that exists between different kinds of nudges. That is, the distinction between what I call ‘counteractive’ and ‘non-counteractive’ nudges. I end by suggesting a revision of the criteria that avoids the problem. (shrink)

This essay discusses epistemic analysis of the fallacy of begging the question. In the literature, there are two prominent epistemic explanations of the fallacy, the objective and the subjective. The objective account bases the analysis of the fallacy on the epistemic relations of the propositions used in the argument. The subjective account bases the analysis on the way the arguers acquire their beliefs in the propositions used in the argument. Arguments that aim to show that a propositional analysis is not (...) flexible enough for fallacy analysis have been taken to be a decisive argument for the subjective approach. Yet, the propositional sense seems to address a central intuition about this fallacy. In this essay, it is argued that both analyses need to be retained. (shrink)
