So you don't think your belief that the scientific mindset is a preferable mindset is a philosophic belief rather than a scientific belief? Because it is, since that is a belief that can't be proven empirically, rather it is reasoned to philosophically.

Now to address your misguided belief on the mind being reduced to the brain.

Under atheistic materialism what is happening is matter in motion. This means even the matter in your brain. What does that mean? Your brain is determined by the laws of physics, chemistry, etc and even your comment was determined. You destroy the possibility of justified knowledge claims under that worldview when taking it to its logical conclusion. Also as Sean Caroll noted, quantum physics and stochastic probabilities don't mean anything, taking the worldview to the logical conclusion means determinism of the movement of matter.

You also can't account for universals and particulars on that view and solve the problem of the and the many.
