Dear Jose, thanks for your anwer. If mathematics does not decide the fundamental properties of matter, what then does? Matter is not a given Ur-stuff, but according to our best theories we have, matter itself emerged from some deeper reality at the point of the big bang. If the properties of matter came about randomly at the point of the big bang, then the cosmos cannot be overall deterministic and governed exclusively always only by the same set of mathematical rules.
You seem to suggest that this set of mathematics is a brute fact without further explanation, together with the known properties of matter being also a brute fact. I would not a priori exclude this to meet reality. But until now, i also cannot see why this view of things should necessarily meet reality other than reassuring it by the brute fact of existent intelligent life which assumes that the Cosmos is programmed to attain the goal of self-realization. If the cosmos was not created some time in the past due to some initial goal to fulfill, what does it then mean that it is 'programmed' to attain the goal of self-realization? Programming something means to choose from a large variety of possibilities whereby each possibility would lead to a different result. Otherwise there would be no need for programming something.
