147. It is as yet scarcely known in the church that in all of man's will and thought and his consequent action and speech, there is an internal and an external, and that from infancy man is carefully taught to speak from the external, however the internal may dissent; and that this is the origin of simulation, flattery, and hypocrisy; and thus man becomes double-minded. But he alone is single-minded whose external thinks and speaks and wills and acts from the internal; and such are meant by the "simple [single]" in the Word (as in Luke 8:15; 11:34; and elsewhere). Nevertheless these are wiser than those who are double-minded. The doubleness and tripleness in every created thing is evident in the parts of the human body. Every nerve therein consists of fibers, and every fiber of fibrils; every muscle consists of bundles of fibers, and these of motor fibers; every artery of coats in a triple series. It is the same in the human mind, whose spiritual organization is of like character, because, as said already, it is divided into three distinct regions; of which the highest, which is also the inmost, is called the celestial, the middle is called the spiritual, and the lowest the natural. It is in this lower region that the minds of all men who deny the holiness of the Word and the Divinity of the Lord carry on thought. But because such have learned also from infancy the spiritual things pertaining to the church, and accept these, but place them beneath natural things (that is, scientific, political, and civil-moral matters of various kinds), also because these spiritual things occupy the lowest part of the mind, which is nearest to speech, it comes to pass that when such persons speak in churches and public assemblies they speak from these; and what is wonderful, they are quite unaware at the time that they are not speaking and teaching from a belief in them. But when they are in freedom, as they are in privacy, the door that has closed the internal of their mind is opened, and then at times they laugh at what they had before preached publicly, saying in their hearts that theology is a specious snare for catching doves.
