Abstract

In this paper, I propose a new framework for the general internalism/externalism debate about reasons. My aim is to defend a novel account of internalism that at least allows for the possibility of a more "realist" conception of reasons- thus avoiding simply begging the question (as Williams himself seems to do) against many recent externalist thinkers like Hampton, Scanlon, McDowell, and Parfit - while still somehow retaining a deep connection between reasons to act and an agent's motivations. What is crucial to observe here is that Williams' intemalism relies upon two logically independent premises: on the one hand, a negative "skeptical" thesis denying we have any reason to believe that values - and the reasons associated with them - exist in any realist way independent of individual agents; and on the other hand, a positive "subjectivist" thesis controversially maintaining that all reasons for action are instead in some sense necessarily related to each particular agent's subjective motivations. I think we should reject Williams' widely-disputed "subjectivist" thesis. Rather, by endorsing only Williams' former premise, we are able to formulate a more modest "skeptical" version of intemalism – or what I call ‘skeptical internalism’ – which, unlike Williams' explicitly "subjectivist intemalism", at least allows for the externalist view that values exist in a realist way totally independent of us. We suspend judgment, however, about whether any such values do exist - where significantly, an individual agent's motivations somehow play a constitutive role in terms of assessing what values she even has reason to affirm. Such so-called "skeptical internalism" has several advantages over Williams' own view. As we will see, it not only helps usto bypass the current terminological deadlock, but also allows us to better focus upon what may be the most crucial difference between internalism and extemalism, which rests not so much in how each camp chooses to define what a reason is, but rather in how they understand the nature of rational disagreement itself. This specific worry constitutes perhaps the main crux of the entire intemalist/extemalist debate, and I argue that, in the end, skeptical internalism provides a much more satisfying analysis of the underlying ethical import of such rational disagreement than either of its two main rivals, extemalism or Williams' own subjectivist accountof internalism.
