Thinking a bit about infinite regresses in justification. My argument in a paper I published recently in this blog (otherwise unpublished and five years old...!) was that when I say I have a good reason (a good justification, a reliable process etc) I am somehow deferring and coupling, that is, deferring to a reason that I endorse and coupling my belief to an existing and accepted chain of reasons. The issue, of course, is whether I can buy the justification of my belief by coupling it to an infinite chain of reasons or by deferring to an infinite process. I don't know. But it is interesting to bite the bullett and claim that there is nothing else to justification than good deferral and good coupling. That is, deferral to a commonly accepted reason and coupling to a commonly accepted (infinite) chain. After all, justification always makes appeal to accepted reasons. These reasons can be out there in chains and processes and to justify could be no more than to accommodate a belief to them. If I am a good detector of red - because the chain that starts with me being a good detector of detectors of red and goes on to me being a good detector of detectors of detectors of red etc is out there to be used -, I can say I'm justified in spotting something red.
I´ve been wondering about whether we can formulate something about contingency along the lines of a principle of irreduction: aucune chose n´est par elle-même contingent ou necessaire . The principle asserts that necessity is always contingent on underlying fixed things: something is physically necessary (or contingent) given the fixed laws of nature, something is deontically contingent - allowed - or necessary - mandatory - given the fixed ethical rules (or laws of the land). Finally, something is logically necessary (or necessary simpliciter) given a fixed logic. The irreducible diversity of ethical rules, the absence of eternal laws of nature and the plurality of logical systems, if accepted, makes necessity relative to those parameters. An aggiornamento of Heraclitus would have that nothing is necessary comes what may. Surely, of couse, if there is no absolute necessity, there is no absolute contingency. We can then say that in a broader, more abstract level, things are up for grab...
