Thats just a long winded way of saying that the subset of mathematical truth which does the same job as physics—predicting things about the world—is the same as physical truth. Which is a tautology.
The problem is that mathematical truth is larger than the set of physical truths and a lot of it is physically useless.… and the set of mathematical truths is larger than the set of physical truths because a lot of it is physically useless.
If you accept that the existence of mathematical truths beyond physical truths cannot have any predictive power, then how do you reconcile that with this previous statement of yours:
Presupposing things without evidence
As you can see, I am not doing that.
I will say again that I don’t reject any mathematics. Even ‘useless’ mathematics is encoded inside physical human brains.
If you accept that the existence of mathematical truths beyond physical truths cannot have any predictive power,
If they did have predictive power, they would be physical truths.
I will say again that I don’t reject any mathematics. Even ‘useless’ mathematics is encoded inside physical human brains.
And wrong mathematics, and stuff that isn’t mathematics at all. The observation you keep making doesn’t explain anything … it doesn’t tell you what maths is, and it doesn’t telly you what makes true maths true … so it’s not an explanatory reduction … so it’s not a reduction at all, as most people use the term.
