What follows is a series of posts of what C. S. Lewis said about the duality of Man in Miracles:
When we are considering Man as evidence for the fact that this spatio-temporal Nature is not the only thing in existence, the important distinction is between that part of Man which belongs to this spatio-temporal Nature and that part which does not: or, if you prefer, between those phenomena of humanity which are rigidly interlocked with all other events in this space and time and those which have a certain independence. These two parts of a man may rightly be called Natural and Supernatural: in calling the second “Supernatural” we mean that it is something which invades, or is added to it, the great interlocked event in space and time, instead of merely arising from it [the indwelling of the Holy Spirit as Counselor sent to believers in repentance by the resurrected Jesus Christ - added by the blog author]. On the other hand this “Supernatural” part is itself a created being - a thing called into existence by the Absolute Being and given by Him a certain character or “nature.” . . . There is, however, a sense in which the life of this part can become absolutely Supernatural, i.e. not beyond this Nature but beyond any and every Nature, in the sense that it can achieve a kind of life which could never have been given to any created being in its mere creation. . . . The rational part of every man is supernatural in the relative sense - the same sense in which both angels and devils are supernatural. But if it is, as the theologians say, “born again,” if it surrenders itself back to God in Christ, it will then have a life which is absolutely Supernatural, which is not created at all but begotten, for the creature is then sharing the begotten life of the Second Person of the Deity. . . . Finally, Christian writers use “spirit” and “spiritual” to mean the life which arises in such rational beings when they voluntarily surrender to Divine grace and become sons of the Heavenly Father in Christ. . . . the regenerate man will find his soul eventually harmonized with his spirit by the life of Christ that is in him.
This series of quotations concludes the posts taken from C. S. Lewis’ book, Miracles, that strongly support the concept of dualist interactionism between the immaterial Mind of God and mind of Man through God’s created neural synaptic networks of the brain.
