Empirical nature of meta mathematics: the philosophy of mathematics of Roberto Magari.

*(Italian. English summary)*Zbl 1402.03009Summary: Roberto Magari (1934–1994), a well-known algebraist, is unanimously recognized as a component of the small group of mathematicians and philosophers to whom we owe the revival of mathematical logic in Italy in the early 60s of the last century. Through the analysis of some unpublished or not well known papers, we tried with this research to reconstruct his philosophy of mathematics. The result was the image of a scholar whose philosophy bridged two eras: rooted in a conception of mathematics we could say “structuralist” according to a trend that culminated with “Bourbaki”, but open to the new requirements emerging in philosophy of mathematics in the early 70s, tending to enhance the importance of heuristic methods.
