I argue that K ⊆ E is false, and indeed that it is so for a reason that Williamson himself essentially provides in arguing against the thesis that, if one has a justified true belief in P, P is part of one’s evidence: together with a very plausible principle governing the acquisition of knowledge by nondeductive inference based on evidence, K ⊆ E leads, in a sorites-like fashion, to what would seem a series of unacceptably bootstrapping expansions of one’s evidence. I then develop some considerations about the functions of and conditions for evidence which are suggested by the argument against K ⊆ E. I close by discussing the relationship of the argument with anti-closure arguments of the style exemplified by the preface paradox: I contend that, if closure is assumed, it is extremely plausible to expect that the diagnosis of what goes wrong in the preface-paradox-style argument cannot be used to block my own argument.engK ⊈ Ejournal article1933-1592https://doi.org/10.1111/phpr.12365https://onlinelibrary.wiley.com/doi/10.1111/phpr.12365https://produccioncientifica.ucm.es/documentos/61fa8a54565bff40e6e7b736restricted access165KnowledgeEvidenceFilosofíaTeoría del conocimiento72 Filosofía7201 Filosofía del Conocimiento7201.02 Epistemología
