@Olivier5,
No one appealed to theology just to a holistic approach to logic, simple common sense don't make divides between big n small, the sky or the earth, man and the Universe.
Dualism if you know what it entails requires a magic relationship between two fundamental kinds of substances in the Universe the Soul and the body which includes the brain. The last two obey relations of cause and effect along with the environment, as for the Soul, well that's reserved for the esoteric dreamers you were talking about!
...again irony keeps flowing from your own wording as you make it up...
