(5) Lastly, The nature of the difference between the life of a man merely natural and the life of a beast. 251. (1) What the natural man is, and what the spiritual man. Man is not man from face and body, but from understanding and will; therefore by the natural man and the spiritual man is meant that man's understanding and will are either natural or spiritual. The natural man in respect to his understanding and will is like the natural world, and may be called a world or microcosm; and the spiritual man in respect to his understanding and will is like the spiritual world, and may be called a spiritual world or heaven. From which it is evident that as the natural man is in a kind of image a natural world, so he loves those things which are of the natural world; and that as the spiritual man is in a kind of image a spiritual world, so he loves those things which are of that world, or of heaven. The spiritual man indeed loves the natural world also but not otherwise than as a master loves his servant through whom he performs uses. Moreover, according to uses the natural man becomes like the spiritual, which is the case when the natural man feels from the spiritual the delight of use; such a natural man may be called spiritual-natural. The spiritual man loves spiritual truths; he not only loves to know and understand them, but also wills them; while the natural man loves to speak of those truths and also do them. Doing truths is performing uses. This subordination is from the conjunction of the spiritual world and the natural world; for whatever appears and is done in the natural world derives its cause from the spiritual world. From all this it can be seen that the spiritual man is altogether distinct from the natural, and that there is no other communication between them than such as there is between cause and effect.
