Despite their shared empiricism, it is tempting to regard Locke and Berkeley as natural enemies when it comes to religious epistemology. Locke's religious epistemology has recently been much discussed,1 and the scholarly consensus is that, as Michael Ayers aptly put it, Locke's "evident purpose" in his theorizing on this subject "was to clip the wings of revelation."2 Locke's whole Essay is characterized by a modest, if not skeptical, epistemology and has as one of its key conclusions the denial that genuine knowledge is to be had in revealed religion. Berkeley's religious epistemology has received considerably less critical attention, but it certainly seems that he is out to defend claims to religious knowledge. His aim, in his well-known early works, is to identify and refute "the grounds of Scepticism, Atheism, and Irreligion,"3 and the grounds he identifies are Locke's doctrines of abstraction and material substratum. To all appearances, (future) Bishop Berkeley, like Bishop Stillingfleet before him, is out to protect the religious establishment from Locke's wing-clipping.In this article, I argue that these appearances are deceiving. This simplistic picture is contradicted by later works in which Berkeley is decidedly pessimistic about the prospects for religious knowledge, and discusses the matter in strikingly Lockean terms. In these late works, Berkeley selfconsciously endorses the main principles of Locke's religious epistemology and, in doing so, he does not contradict any of the major theses of his early works. Recognizing this fact will help to clarify Berkeley's relationship to Locke and to prominent critics of Locke, such as Stillingfleet. In particular, I will argue that one of Berkeley's main aims in the famous early works was to show that Stillingfleet and others had misidentified the grounds of skepticism, atheism, and irreligion in Locke's philosophy. Locke's epistemology is innocent; the doctrines of matter and abstraction are to blame.I. THE TEMPTING NARRATIVEIn this section, I lay out in more detail the story I will call the "Tempting Narrative," which sees Berkeley as fitting into the tradition of religious critics of Locke's epistemology.4 I begin with a description of Locke's religious epistemology and an overview of the critical responses, then proceed to show how and why Berkeley might be thought to fit into this tradition.1.1 Locke's Religious EpistemologyThe general tendency of Locke's philosophy is toward epistemic humility or, as Locke's opponents called it, skepticism. Locke famously endorsed a strong form of epistemic individualism, arguing that, "We may as rationally hope to see with other Mens Eyes, as to know by other Mens Understandings."5 However, the individual understanding, he says, "comes exceeding short of the vast Extent of Things."6 Failure to recognize our limitations, Locke argued, leads to confusion and doubt. In order to have any secure knowledge at all, we must first know that there are many things we do not (and cannot) know. Locke's moderate skepticism is thus advertised as the only antidote to "perfect Scepticism,"7 or the denial that there is any knowledge at all.In the chapter "Of Faith and Reason"8 in the Essay, Locke applies these general principles to religious questions. Here, as elsewhere, Locke believes that people have supposed that knowledge was available, or even that knowledge was actually possessed, where only probable belief is possible. Locke describes this error as a confusion regarding the "distinct provinces" of faith and reason and says that it "may possibly have been the cause, if not of great Disorders, yet at least of great Disputes, and perhaps Mistakes in the World."9 It is likely that Locke intends this as an ironic understatement, since it is clear from his political writings that Locke believes that excessive religious confidence is not merely a possible cause of disputes and mistakes, but an actual cause of violence and persecution. …
