A self-fulfilling fallacy (SFF) is a fallacious argument whose conclusion is that the very fallacy employed is an invalid or otherwise illegitimate inferential procedure. This paper discusses three different ways in which SFF’s might serve to justify their conclusions. SFF’s might have probative value as honest and straightforward arguments, they might serve to justify the premise of a meta-argument or, following a point made by Roy Sorensen, they might provide a non-inferential basis for accepting their conclusion. The paper concludes with an assessment of the relative merits of these proposals

Epistemological Disjunctivism (ED) is the view that rational support for paradigm cases of perceptual knowledge that P comes from seeing that P – a state that is both factive and reflectively accessible. ED has the consequence that if I see that there is a barn before me, I can thereby be in a position to know that I am not in fake barn country. It is argued that this is a problem. The problem is distinct from familiar complaints about Neo-Mooreanism and easy knowledge. Potential ways of avoiding this problem are proposed. It is argued that they do not succeed. There is a way out of ED's fake barn problem but many will likely find it inhospitable.

Several subjects are fully convinced that they are brains in vats whose experiences are hallucinatory. They confront a ‘skeptic’ who raises the possibility that they are not brains in vats who lack and hallucinate hands but ‘brains in skulls’ who have hands and see them. Familiar responses to skepticism are offered in support of the claim that the subjects know they do not have hands. The philosophical significance of this looking-glass approach to skepticism is also discussed. It is suggested that these familiar responses to skepticism do not achieve anything because, if we begin from the assumption that we are brains in vats, we can employ those same responses to skepticism to support the claim that we know we do not have hands. One interlocutor argues that things are not so dismal. The main conversation is framed by a discussion among night watchmen at some sort of skepticism laboratory.
