Dualism that results from the Searlean theory of mind is naïve dualism; a naïve distinction between body and mind Searle is ready to accept the commonsensical distinction between the mental and the physical. There is a gap between the physical and the mental because, according to Searle, the physical causes the mental states.  The mental phenomena, which are, in principle, conscious phenomena are logically irreducible to the microstructure of the physical organism, which causes them. It is because, so far as the explanation of the mind is concerned, there is a strong conception of causal asymmetry between mind and body. The asymmetry relationship reveals the causal function of the brain processes and the intentional functions of the Network of mental states. Furthermore, the Network is autonomous having its own function and the function in principle pertains to the realm of consciousness. Consciousness is intrinsic to the mental states which possess other features like phenomenality, subjectivity, intentionality, etc. These phenomena can be said to constitute the mental realm. The mental is purely non physical because it embodies certain nonphysical properties which are irreducible to the non-physical functions. Moreover, for Searle, the mental states emerge in an evolutionary process and thus are real. In this regard his notion of irreducibility of the mental states parallel to the Cartesian notion of irreducibility. Moreover, the Searlean notion of irreducibility of the mental should not be interpreted in the sense of Cartesian notion of substance. It is because the Cartesian theory leads to Substance- dualism. In this sense Searlean dualism differs from the Cartesian substance-dualism.
