Abstract:On a traditional view, the primary role of a mathematical proof is to warrant the truth of the resulting theorem. This view fails to explain why it is very often the case that a new proof of a theorem is deemed important. Three case studies from elementary arithmetic show, informally, that there are many criteria by which ordinary proofs are valued. I argue that at least some of these criteria depend on the methods of inference the proofs employ, and that standard models of formal deduction are not well-equipp… Show more
“…In Avigad (2006), I addressed one small aspect of mathematical understanding, namely, the process by which we understand the text of an ordinary mathematical proof. I discussed ways in which efforts in formal verification can inform and be informed by a philosophical study of this type of understanding.…”

“…Rav is not the only one who assigns to proofs a role that goes well beyond demonstrating that a theorem is true and why a theorem is true. Avigad (2006) lends support to Rav's central thesis when he says:…”
“…That is, in order to be such, a proof should be either (i) formalisable, or (ii) fully formalised. 1 This view of proof has emerged out of the foundational crisis at the beginning of the 20th century. The foundational concerns brought about the need for longstanding conceptions of mathematical knowledge to be revised, and produced a shift of attention in mathematical epistemology from the actual ways of acquiring mathematical knowledge to the ways of securing the certainty of mathematical results.…”

The aim of this paper is to provide epistemic reasons for investigating the notions of informal rigour and informal provability. I argue that the standard view of mathematical proof and rigour yields an implausible account of mathematical knowledge, and falls short of explaining the success of mathematical practice. I conclude that careful consideration of mathematical practice urges us to pursue a theory of informal provability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
