After a long time, people are still debating over “Cartesian-like Dualism” (CLD), i.e. towards the separation of “res-extensa” from “res-cogitans”. Since we suspect that this is due to a general attraction of mind towards the darkness of metaphysics, we have investigated the mental origin of this attraction. In human mind, we can envisage three different functional levels emerging one from the other like in a Matrioska; the three levels cause the arousal of as many forms of “dualisms”: 1) The 1st-level (...) corresponds to the “Dual-state” of mind, an archetypic dualism made of Unconscious Mind (UM, the domain of biophysical/biochemical signals) and Conscious Mind (CM, the domain of thoughts, images and sounds), genetically committed to reciprocal and fruitful interactions. 2) the 2nd-level corresponds to “Double-perspective” dualism; it emerges from CM’s splitting into two opposite perspectives: the 1st-order perspective (1PP) (subjective, emotional, Self-oriented, etc.) and the 3rd-order perspective (3PP) (rational, objective, Self-detached, etc.), that are in psychological contraposition. During individual growth, Ego-sense installs in CM with the illusion of possessing FW, and dominates 1PP. Conversely, 3PP is typically interested in scientific argumentations and investigations; so, 3PP confutes 1PP’s convictions on scien-tific bases (e.g. 1PP’s conviction that the binomial Ego-FW is real). Yet, on the one hand, 3PP hasn’t got a scientific alternative to explain “who we really are”, on the other hand, 1PP exhibits a great success in everyday life cognition. Then, we necessarily step over the dualism of the 3rd-level, “Cartesian-like Dualism” (CLD). The emotional origin of this CLD holds back 1PP’s trick to claim its supremacy over 3PP. (shrink)
