Defining things according to reality isn't always productive even in science. Many discoveries (e.g. black holes) are purely the result of mathematics. In software development, we have to add order to things, and even create order where none is obvious. Reality is far too complex for us to model it exactly, and we need to ensure that our systems are consistent, which means devising predicates that (we hope!) mirror reality.
