The Sensitivity Principle in Epistemology: The enduring trouble with tracking

This chapter shows that explanationist counterfactualism (EC) is not threatened by objections like those leveled by Sosa, Saul Kripke, and Williamson. It is reported that Kripke offers a case like the following: Henry, still out on his drive, believes that there is a red barn before him. Besides handling the cases put forth by Sosa, Kripke, and Williamson, the chapter's proposal has another virtue: it clarifies and helps bring into focus the recent literature on skepticism. One would need to do more in order to determine whether (EC)'s explanatory condition includes demands that concern belief- forming methods and perceptual equivalence. it might very well be that we need to identify and examine other demands of that condition. EC pays real dividends in helping us focus our attention on key elements in the skeptical debate, elements that might help us finally to put an end to that debate.
