What kind of things are numbers?

A talk and discussion about numbers

In what manner do numbers exist? Are they the subjective products of mental processes? Or do they, as Plato would have it, belong to a separate realm of ideal existence that our mathematical thoughts somehow access? In what way might the existence of the number 4 be like that of the North Sea?

Alexander Paseau is a Lecturer at the University of Oxford and a fellow of Wadham College. He is the co-editor of Mathematical Knowledge (Oxford University Press, 2007). He is writing a general introduction to the philosophy of mathematics under the provisional title, What is a Number?
