Quasiempiricism in mathematics

Quasi-empiricism in mathematics is the movement in the philosophy of mathematics to reject as pointless the foundations problem in mathematics, and re-focus philosophers on mathematical practice itself, in particular relations with physics and social sciences.

A key argument is that mathematics and physics, as perceived by humans, have grown together, may simply reflect human cognitive bias, and that the rigorous application of empirical methods or mathematical practice in either field is insufficient to disprove credible alternate approaches.

Hilary Putnam argued in 1975 that real mathematics had accepted informal proofs and proof by authority, and made and corrected errors all through its history, and that Euclid's system of proving theorems about geometry was peculiar to the classical Greeks and did not evolve in other mathematical cultures in China, India, and Arabia. This and other evidence led many mathematicians to reject the label of Platonists, along with Plato's ontology—which, along with the methods and epistemology of Aristotle, had served as a foundation ontology for the Western world since its beginnings. A truly international culture of mathematics would, Putnam and others argued, necessarily be at least 'quasi'-empirical (embracing 'the scientific method' for consensus if not experiment).

Eugene Wigner had noted in 1960 that this culture need not be restricted to mathematics, physics, or even humans. He stated further that "The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning."

This simultaneous "hope" and "bafflement" regarding the undeserved "gift" was a frank admission that quasi-empiricism could apply to physics as well, and that other branches of learning need not necessarily be so compatible with mathematics as understood in the context of physics or hard sciences.

Recent work

Two additions to discussions about this concept could be Chaitin's and Wolfram's, albeit these might be considered to be controversial viewpoints. In terms of the former, the work shows an underlying 'randomness' to mathematics; the latter suggests that 'undecidability' might be more than an abstraction and that it may have 'practical' relevance. Both of these are heavily influenced by computational issues. To quote Chaitin: "Now everything has gone topsy-turvy. It's gone topsy-turvy, not because of any philosophical argument, not because of Gödel's results or Turing's results or my own incompleteness results. It's gone topsy-turvy for a very simple reason---the computer!" (Limits of Mathematics). Wolfram's collection of 'undecidables' is another example.
