Can epistemic luck be captured by modal conditions such as safety from error? This paper answers ‘no’. First, an old problem is cast in a new light: it is argued that the trivial satisfaction associated with necessary truths and accidentally robust propositions is a symptom of a more general disease. Namely, epistemic luck but not safety from error is hyperintensional. Second, it is argued that as a consequence the standard solution to deal with this worry, namely the invocation of content variation, fails. Third, it is considered whether the condition can serve some restricted theoretical role; the hypothesis is rejected. Finally, it is tentatively suggested that epistemic luck’s hyperintensionality derives from its being an explanatory notion, and an analogy is drawn with failures of probabilstic conceptions of explanation in the philosophy of science.

Knowledge excludes luck. According to the received view, this intuition reveals that knowing is essentially modal in character. This paper demurs. Either knowledge does not exclude luck, or the entailment reveals nothing about its conceptual character. It is argued that knowledge excludes accidentality, and that this notion is not modal but causal‐explanatory. There are three central tasks. The first is to explicate the concept of accident. The second is to argue that the concepts of luck and accident are “intensionally distinct,” which is to say that no member of the intension of either holds on both. The third is to argue that an anti‐accident requirement on knowledge is preferable to an anti‐luck analogue on abductive grounds.

The proper function of the heart is pumping the blood. According to what we call the type etiological view, this is because previous tokens of the type HEART were selected for pumping the blood. Nanay :412–431, 2010) argues that the type etiological view is viciously circular. He claims that the only plausible accounts of trait type individuation use proper functions, such that whenever the type etiological view is supplemented with a plausible account of trait type individuation, the result is a view that uses proper functions to explain proper functions. We refine this objection, and argue that Nanay at most establishes a potentially benign definitional circularity. However, we show that the type etiological view’s reliance on types nevertheless generates a vicious regress. Hence the type etiological view is false. We reject dispositional and modal alternatives to the type etiological view for the reason that they either cannot accommodate malfunction, or do so at the cost of proliferation; and then formulate a novel token etiological view that overcomes both problems because it makes no reference to trait types.

Throughout the years, Sosa has taken different views on the safety condition on knowledge. In his early work, he endorsed the safety condition, but later retracted this view when first developing his much discussed virtue epistemology. Recently, Sosa has further developed his virtue theory with the notion of competence and has developed an accompanying, modified safety condition that he maintains is entailed by that theory: the SSS-safety condition. Sosa's view is that this condition holds on both knowledge and action, because both knowledge and action are the manifestations of competence. The SSS-safety condition, roughly, says that if S were to make an attempt at φ-ing under certain specified shape-situation pairs, holding fixed their seat, then S would φ. The argument of this paper is that this new SSS-safety condition does not hold on either knowledge or action. We argue for this conclusion by providing a principled way to generate counter-examples to the condition for both knowledge and action. The reasoning is that there can exist a non-empty symmetric difference between the sets of shape-situation pairs under which distinct agents can manifest their epistemic and pragmatic competences, and if there can exist such a symmetric difference then the SSS-safety condition fails to hold.
