Well, that's an odd question.
Not to anyone who understands western philosophy.

Because the evidence for a physical brain is the same as for an ideal brain.
It's not, actually. Idealism has to assume the existence of the real, in order to account for the existence of any non-hallucinogenic/mystical
ideas or
perceptions, and to distinguish the
idea from
reality. But Physicalism is of a different kind; it recognizes ONLY physical reality as real, and simply denies any evidence that ideation has any real-world effect.
What the first positively
requires, the second simply
refuses to recognize: namely, the existence of an "other" to reality.
Descartes (or more precisely, Descartes chosen gnostic methodology, not the man himself, obviously) is squarely in the
epistemological not
ontological realm. It's nowhere near denying the
existence of reality, which Descartes does not even bother to interrogate; but rather it's interrogating the extent and possibility of human certainty or knowledge
about reality. The question of whether there actually IS a reality is really not on the table; whether or not human beings can know with certainty there IS an external reality is his question-of-the-moment.
So I'm not sure you get any mileage from Descartes...at least, not
on ontology. You'd have to show me you do.
