Ideas of Juan Comesaña, by Text

[American, fl. 2005, Professor at the University of Arizona.]

2011 Reliabilism
4.1 p.178 In a sceptical scenario belief formation is unreliable, so no beliefs at all are justified?
     Full Idea: If the processes of belief-formation are unreliable (perhaps in a sceptical scenario), then reliabilism has the consequence that those victims can never have justified beliefs (which Sosa calls the 'new evil demon problem').
     From: Juan Comesaña (Reliabilism [2011], 4.1)
     A reaction: That may be the right outcome. Could you have mathematical knowledge in a sceptical scenario? But that would be different processes. If I might be a brain in a vat, then it's true that I have no perceptual knowledge.
4.3 p.182 How do we decide which exact process is the one that needs to be reliable?
     Full Idea: The reliabilist has the problem of finding a principled way of selecting, for each token-process of belief formation, the type whose reliability ratio must be high enough for the belief to be justified.
     From: Juan Comesaña (Reliabilism [2011], 4.3)
     A reaction: The question is which exact process I am employing for some visual knowledge (and how the process should be described). Seeing, staring, squinting, glancing.... This seems to be called the 'generality problem'.
4.4 p.185 Reliabilist knowledge is evidence based belief, with high conditional probability
     Full Idea: The best definition of reliabilism seems to be: the agent has evidence, and bases the belief on the evidence, and the actual conditional reliability of the belief on the evidence is high enough.
     From: Juan Comesaña (Reliabilism [2011], 4.4)
     A reaction: This is Comesaña's own theory, derived from Alston 1998, and based on conditional probabilities.
