Again, mathematical knowledge is of another type. It's a mathematical theorem that the angles of a triangle in Euclidean space sum to two right angles. It's an empirical (or physical) question whether this theorem applies to the universe. All connections of mathematics with the world are empirical. The whole question of using mathematics to describe real-world items is hard. Of course, applied mathematics isn't physics either.

Attacks on mathematics have generally been milder than those on physics, chemistry, biology, or medicine. It seems strange that one would attack a man-made construct such as mathematics, but it's done in colleges and even here on FR.

Dr. S, I am not attacking mathmatics. I am also not attacking science. What I was trying to establish was
"mathematical knowledge is of another type."

My point is that the truth of 2+2=4 or If p then q, p = true, therefore q= true would still be true even without an observable reality. (Although the usefulness of that truth would be limited.)

Your original post on this thread seemed to "deify" (if I may be allowed a pun) scientific truths as the sum total of all useful knowledge. I was only trying to point out that truth discerned by observation, even when that observation occurs within the framework of the "Scientific Method", is not the end all, be all of knowledge, truth, and fact. I find that all knowledge, with a reasonable basis for the truth of that knowledge, is useful.
