Abstract
A distinctive approach to the theory of knowledge is described, known as anti-luck epistemology. The goal of the paper is to consider whether there are specific features of this proposal that entails that it is committed to pragmatic encroachment, such that whether one counts as having knowledge significantly depends on non-epistemic factors. In particular, the plausibility of the following idea is explored: that since pragmatic factors play an essential role when it comes to the notion of luck, then according to anti-luck epistemology they must likewise play an essential role in our understanding of knowledge as well. It is argued that once anti-luck epistemology is properly understood—where this means, in turn, having the right account of luck in play—then this putative entailment to pragmatic encroachment does not go through.

Notes
Pritchard (2004, 2005, 2007, 2012a, b, 2015a, b), and Pritchard et al. (2010, chs. 1–4). Note that these days I express the view in terms of the closely related notion of risk, and hence argue for an anti-risk epistemology—see Pritchard (2015c, 2016, 2017a, 2020). Since nothing turns on the differences between luck and risk for our purposes, in what follows I will focus on the former. Relatedly, the defence of anti-luck epistemology offered here with regard to pragmatic encroachment will apply, mutatis mutandis, to anti-risk epistemology. For further discussion of how the notions of luck and risk are related to one another, see Pritchard (2015c). See also endnote 2.
I will be explaining the motivations for this claim below. For a recent defence of the thesis that anti-luck epistemology is committed to pragmatic encroachment, see Ballantyne (2011).
For more on the modal account of luck, see Pritchard (2005, ch. 6, 2014, 2019). See also Pritchard and Smith (2004). For further discussion of the notion of luck, including both defences of other proposals and critiques of the modal account, see Rescher (1990, 1995), Coffman (2007, 2009, 2015), Lackey (2008), Steglich-Peterson (2010), Levy (2011), McKinnon (2014), and Hales (2016).
The modal account of luck follows the standard line of ordering possible worlds in terms of their similarity to the actual world (i.e., roughly, how much needs to change about the actual world to take one to the target possible world). See Stalnaker (1968) and Lewis (1973, 1987). For further defence of this account of possible worlds in the context of the modal account of luck—including such issues as the world order and border problems, and the relevance of determinism and indeterminism—see Pritchard (2005, ch. 6, 2014).
This example is, of course, from Chisholm (1977, p. 105).
There are some complications in this regard—see Pritchard (2016)—though they aren’t relevant to our current discussion.
See, for example, Pritchard (2012b).
The bank case is originally due to DeRose (1992), though it wasn’t employed in support of a pragmatic encroachment thesis about knowledge (but rather in support of a contextualist thesis regarding knowledge ascriptions).
Henceforth I will drop the qualifier ‘about knowledge’, and take it as given that the pragmatic encroachment thesis specifically concerns knowledge (i.e., rather than another epistemic standing).
For example, suppose one defends a reliability condition on knowledge. Is there a fact of the matter as to what the exact threshold of reliability is for this condition to be satisfied? That seems somewhat implausible, but it is hard to see how one could reject the idea of a precise threshold of reliability without thereby introducing some degree of vagueness into one’s epistemic condition on knowledge.
See Ballantyne (2011) for a defence of the claim that pragmatic encroachment is a desirable consequence of anti-luck epistemology.
See Pritchard (2005, ch. 6).
See Pritchard (2005, ch. 6) for my original defence of this point.
It might matter in this regard whether one is using the notion of belief in a broad everyday sense or in a more specific fashion that is of particular relevance to epistemology. Very roughly, according to the latter usage belief is that propositional attitude that is a constituent part of propositional knowledge (especially rationally grounded propositional knowledge). The idea that believers must have some standing desire for their beliefs to be true—that their believing in some sense is aimed at the truth—looks far more plausible on the narrower conception of belief than when cast in terms of the everyday notion of belief (which might have no such implication). In any case, it is obviously the latter notion that is salient to our current concern with epistemic luck. For further discussion of this narrower notion of belief, and some of its epistemological ramifications, see Pritchard (2015b, part two, 2018). For more general discussion of the different notions of belief in play in the philosophical literature, see Stevenson (2002).
See Ballantyne (2012) for further discussion of how he understands the relationship between luck and interests.
See especially Pritchard (2014). See also my discussion of the closely related notion of risk in this regard in Pritchard (2015c), which I also argue should not be partially cast in terms of a corresponding significance condition. For two distinct treatments of the relationship between luck and risk, see Broncano-Berrocal (2015) and Navarro (2019).
