The aim of this paper is to clarify the use of contrast cases—which are pairs of cases in which the feature under examination is varied and all else is held fixed—in ethical methodology. In another paper, I argue that we must reject a separability principle which is thought to allow one to use contrast cases to infer truths about intrinsic value. Here I offer a different criticism that has a positive upshot about what we are licensed to infer from contrast cases. This provides clarification about the epistemic use of contrast cases in value theory and insight into what we can glean from contrast cases.

The bare‐difference methodology is considered to be a powerful tool in ethical reasoning. The underlying idea is that we can identify the intrinsic evaluative significance of some feature by constructing contrast cases or bare‐difference cases, i.e., two cases that hold everything constant but for the feature of interest. While this popular methodology has been challenged by prominent philosophers such as Kagan, Thomson, and Kamm, it is intuitively appealing because, as Perrett identifies, the methodology appears to share the same logical structure as a fruitful scientific procedure. In this paper, I argue that examining this ‘scientific analogy’ is crucial to understanding both the limitations and the prospects for ethical bare‐difference reasoning. I expand upon Perrett's discussion of the scientific analogy and examine another relevant similarity. I then highlight two relevant dissimilarities between ethical bare‐difference reasoning and its scientific analogue. Though these differences threaten to undermine the analogy, I show how the analogy might be mended to better bring the ethical methodology in line with its scientific counterpart and avoid challenges to ethical bare‐difference methodology raised by philosophers in the literature.

Following Moore, value invariabilists deny that the intrinsic value of something can be affected by features extrinsic to it. The primary focuses of this paper are (i) to examine the invariabilistic thesis and expand upon how we ought to understand it, in light of contemporary axiological distinctions, and (ii) to argue that distinguishing between different kinds of invariabilism provides resources to undermine a prominent argument against variabilism. First, I use two contemporary axiological distinctions to clarify what kind of value the invariabilism debate concerns (final value). Then I show how the distinction between personal value and value simpliciter reveals different variabilistic theses, depending on what type of final value one thinks may be affected by extrinsic features. Using this insight, I challenge an argument for final value simpliciter invariabilism. Variabilists offer the example of the vicious being pleased as a counterexample to the claim that pleasure’s final value is invariant to contextual changes. The argument that I examine purports to show that this case actually supports invariabilism about pleasure’s final value simpliciter, because the best explanation for why the vicious being pleased is a fitting object of indignation is that the vicious person’s pleasure is finally valuable simpliciter. I argue that this argument fails because the vicious person’s pleasure being finally personally good for them better explains why an attitude of indignation is fitting. I address two objections and conclude with remarks about how my results might inform future research on value invariabilism.
