What is Mathematics?

4th ed. Jan 2024; 3rd ed. May 2023; 2nd ed. Dec 2009; 1st ed. Sep 2004

“It is not philosophy but active experience in mathematics itself that alone can answer the question: `What is Mathematics?'” – Richard Courant & Herbert Robbins, 1941, What is Mathematics?, Oxford University Press)

“An adequate presentation of any science cannot consist of detailed information alone, however extensive. It must also provide a proper view of the essential nature of the science as a whole.” – Aleksandrov, 1956, Mathematics: Its Content, Methods, and Meaning

‘What is mathematics?’ Much ink has been spilled over this question, as can be seen from the selection of ten respected responses provided in the footnote1, with seven book-length answers, and three written in the current millenium. One might well ask, is there anything new that can be said, that should be said? We’ll start by clarifying what a good answer should look like, and then explore the answer proposed.

The rest of the paper follows the structure below:

   1. Criteria for a Good Definition of Mathematics
   2. Definition 1: covering mathematics up to the end of the 18th century (1790s)
   3. Two Perspectives 
       Mathematics as Dialectic (Lakatos)
       Mathematics shaped by its Anthropology (Hoyrup)
   4. Definition 2: covering all mathematics, including contemporary mathematics
   5. The emergence of contemporary mathematical practice from 1800s onward
   6. Three Facets of Mathematics
       1. Mathematics as an Empirical Science
       2. Mathematics as a Modeling Art
       3. Mathematics as an Axiomatic Arrangement of Knowledge
   7. Mathematics "from the inside": Mathematicians writing about Mathematics
   8. Continue Reading
   9. References
