The main aim of this paper is to explore why it is so important for Hume to defi ne ‘cause’ as he does. This will shed light on the signifi cance of the natural/philosophical relation (hereafter NPR) distinction in the Treatise. Hume's use of the NPR distinction allows him to dismiss on general grounds conceptions of causation at odds with his own. In particular, it allows him to avoid having to engage in detailed re-interpretation of potentially confl icting theories formulated (...) by natural philosophers. Moreover, it provides an instance of the normative nature of Hume's “science of man.” The paper argues that the NPR distinction - in conjunction with the so-called copy principle - is meant to undercut appeals to the authority of theories not founded on Hume's “principles.” In order to illustrate its claims about Hume, this essay explores some aspects of Newton's natural philosophy. Finally, this paper resolves a long-standing interpretive problem: how to reconcile Hume's two “defi nitions” of causation in the Treatise. (shrink)

In this article, the author offers a discussion of the evidential role of the Galilean constant in the history of physics. The author argues that measurable constants help theories constrain data. Theories are engines for research, and this helps explain why the Duhem-Quine thesis does not undermine scientific practice. The author connects his argument to discussion of two famous papers in the history of economic methodology, Milton Friedman's 'Methodology of Positive Economics', which appealed to example of Galilean Law of Fall (...) in its argument; and Vernon Smith's 'Economics in the Laboratory'. While the author offers some criticism of Friedman and Smith, most of the article is a friendly reinterpretation of their insights. (shrink)

In a 2004 paper, “Hume’s Missing Shade of Blue Reconsidered from a Newtonian Perspective,” Eric Schliesser argues that Hume’s well-known discussion of the missing shade of blue “reveals considerable ignorance of Newton’s achievement in optics,” and that Hume has failed to assimilate the lessons taught by Newton’s optical experiments. I argue in this paper, contrary to Schliesser, that Hume’s views on color are logically and evidentially independent of Newton’s results. In developing my reading, I will argue that Schliesser accepts an (...) overly broad interpretation of the implications of Newton’s experimental results, and takes inadequate account of Hume’s disciplined methodological restrictions on the kinds of experiential evidence that are to be admitted in building the foundations of his science of human nature.

This paper discusses a possible test of Hume's ‘ missing shade of blue’ and whether it might be possible to make some empirical progress on the question. Towards this end seventy-two students were tested to see if they could determine the correct color ratios of missing black and white shades ranging from a consecutive gap of two out of 236 possible combinations, to a consecutive gap of ten of out of 236 possible combinations. On the most difficult test, four of (...) the seventy-two students correctly determined a missing shade, though these same four all claimed to have above-average experience with art. (shrink)

What to do with the missing shade of blue? Some have argued that Hume's famous thought experiment undermines his central doctrine – the ‘copy principle’ – such that he should have revised his whole theory in light of it. Others contend that the MSB is not a true or actual counterexample to the copy principle, but merely an apparent or conceivable one, so that he had no such obligation to revise. In this essay, I argue that even if the MSB (...) is a true counterexample, Hume would not have been obligated to revise his theory, given methodological resources he makes available to himself elsewhere in his work and his overarching empiricist aims. And I offer a new suggestion for why he might have included and even highlighted the MSB in his writings despite its being so very vexing and peculiar. (shrink)

In this article I suggest that section VIII of Hume’s Enquiry Concerning Human Understanding could be read as a contribution to the foundational issues of a characteristic 18th-century enterprise, namely the ‘science of man’. More specifically, it can be read as a summary of his attempt to place this science on an experimental footing, with an awareness of the lessons he has drawn in the previous sections of the Enquiry. This interpretation fits with an overall reading of the work as (...) responding to the epistemological problems that arise in the context of then-contemporary ways of knowledge production. As I argue, this section is relevant for the methodology of a science of human nature. The main problems it addresses are the following. What kind of knowledge can we hope for about human beings, and how should we pursue it? What are the meaningful questions that can be asked, and what is beyond the reach of this kind of inquiry? Answering these questions sets the scope and limits of this science. (shrink)
