THE SYDNEY SCHOOL: MATHEMATICS, THE SCIENCE OF STRUCTURE
AN ARISTOTELIAN REALIST PHILOSOPHY OF MATHEMATICS
We are a school of philosophers of mathematics centred in Sydney, Australia. Our line is realist (about structure and quantity), but Aristotelian rather than Platonist: we hold that mathematics studies real properties of things such as symmetry and continuity . . .

Paul Thagard writes "The current philosophy of mathematics that fits best with what is known about minds and science is James Franklin's Aristotelian realism."
