The New Dualism yatagarasu,
Thank you for being polite. Still, I think your view of history is a little off. I don't believe that science was formed within a materialistic mindset as you claim. It appears to me that modern science began with Copernicus, Bacon, Galileo, Descartes, and others of that time, which was well before materialism became ascendant in the twentieth century. Some have thought of Newtonian mechanics as being materialistic but this appears to be a overreach. (At least it is an overreach to think that it can be applied to absolutely everything, although admittedly many did.) Nonetheless, in the eighteenth and nineteenth centuries, idealism was the dominant philosophy. It was only in the twentieth century that materialism became ascendant and got to be associated with science. Perhaps this somewhat oversimplifies, but it is certainly more correct than your assertion. It appears to me that science has recently gotten away from the scientific method where evidence and reason are important. Scientists have accepted some ideas, such as materialism, that are unsupported by the scientific method.
As for dual aspect theory, this is a theory that mental and physical are fundamentally the same, but still somehow different, so there is a sense that 2=1, which is obviously contradictory. At one time, I tried to make a kind of dual aspect theory work by holding that mind and brain are epistemically different and yet fundamentally the same. This appears to get around the contradiction, but it still does not work. For one thing, there is no real evidence that mind and brain are fundamentally the same. If they were, what would this fundamental unity look like? This appears to be even more mysterious than the brain causing conscious mental experience, and so it is even more mysterious than dualism. One of the main reasons dualism was widely rejected was because it was considered to be mysterious, and so it makes no sense to accept something even more mysterious. (By the way our ignorance of just how the brain causes conscious experience is not a good argument against dualism. It would be like saying that because you don't know why the sun is hot, it must not really be hot.)
