But is it true that different brains can implement the same algorithm? It seems it
is only true because we abstract a certain algorithm from it's various
representation, e.g. as written on paper. Every actual realization, in brains or
computer or on paper is actually slightly different at a microscopic level at least.
We call it "the same algorithm" because we're abstracting a common functionality or
purpose.

But this only shows that mathematical objects exist in the sense that chair exists;
as a abstraction from chairs. So chair isn't identical with any particular chair.

But you can look at it the other way around. The "algorithm" is already the general
high-level property that is common to all the brains and computers implementing.

This looks more like botany than ontology.
