I have this idea that in order to "have" numbers, there has to be a symmetry, and then this symmetry has to "break", or become locally at least, less symmetric than one you assert exists a priori. Numbers arrive when you compare the "globally asserted" symmetry, with the local one which is something you, erm, distinguish locally . . . So, a question about what symmetry is. Is a bar made of iron more or less symmetric than a similar bar which is magnetised? What about say, an iron ball in either case? What about the appearance of numbers?
