1. The Interaction of the Soul and Body

There are three opinions and traditions, which are hypotheses, concerning the Interaction of the Soul and Body, or the operation of the one upon the other, and of the one together with the other: the first is called Physical Influx, the second Spiritual Influx, and the third Pre-established Harmony.

The first, which is called physical influx, arises from the appearances of the senses, and the fallacies thence derived. For it appears as if the objects of sight, which affect the eyes, flow into the thought and produce it; in like manner speech, which affects the ears, appears to flow into the mind, and to produce ideas there; and it is similar with respect to the senses of smell, taste, and touch. Since the organs of these senses first receive the impressions that flow into them from the world, and the mind appears to think, and also to will, according as these organs are affected, therefore, the ancient philosophers and Schoolmen believed that influx was derived from them into the soul, and hence adopted the hypothesis of Physical or Natural Influx.

[2] The second hypothesis, which is called spiritual, and by some occasional influx, originates in order and its laws. For the soul is a spiritual substance, and therefore purer, prior, and interior; but the body is material, and therefore grosser, posterior, and exterior; and it is according to order that the purer should flow into the grosser, the prior into the posterior, and the interior into the exterior, thus what is spiritual into what is material, and not the contrary. Consequently, it is according to order for the thinking mind to flow into the sight according to the state induced on the eyes by the objects before them, which state that mind also disposes at its pleasure; and likewise for the perceptive mind to flow into the hearing, according to the state induced upon the ears by speech.

[3] The third hypothesis, which is called pre-established harmony, arises from the appearances and fallacies of the reasoning faculty; since the mind, in the very act of operating, acts together with and at the same time as the body. Still, every operation is first successive and afterwards simultaneous, and successive operation is Influx, and simultaneous operation is Harmony; as, for instance, when the mind thinks and afterwards speaks, or when it wills and afterwards acts: hence it is a fallacy of the reasoning faculty to establish that which is simultaneous, and to exclude that which is successive.

No fourth opinion concerning the Interaction of the Soul and the Body can be framed in addition to these three; for either the soul must operate upon the body, or the body upon the soul, or both uninterruptedly at the same time.

3. I. There are two worlds: the spiritual world, inhabited by spirits and angels, and the natural world, inhabited by men.

That there is a spiritual world inhabited by spirits and angels distinct from the natural world inhabited by men, has hitherto been deeply hidden, even in the Christian world, because no angel has descended and taught it by word of mouth, nor has any man ascended and seen it. Lest, therefore, from ignorance of that world, and the uncertain faith respecting heaven and hell thence resulting, man should be so far infatuated as to become an atheistic materialist, it has pleased the Lord to open the sight of my spirit, and to raise it into heaven and let it down into hell, and to exhibit to my view the nature of both.

[2] It has thus been made evident to me that there are two worlds, distinct from each other; one, in which all things are spiritual, whence it is called the spiritual world; and the other, in which all things are natural, whence it is called the natural world: and also that spirits and angels live in their own world, and men in theirs; and further, that every man passes by death from his world into the other, and lives in it to eternity. In order that Influx, which is the subject of this little work, may be unfolded from its beginning, it is necessary that some information respecting both these worlds should be provided; for the spiritual world flows into the natural world, and actuates it in all its parts, with both men and beasts, and also constitutes the vegetative principle in trees and herbs.

8. VI. Those two, heat and light, or love and wisdom, flow conjointly from God into the soul of man; and through this into his mind, its affections and thoughts; and from these into the senses, speech, and actions of the body.

The spiritual influx hitherto treated of by inspired men is that from the soul into the body, but no one has treated of influx into the soul, and through this into the body; although it is known that all the good of love and all the truth of faith flow from God into man, and nothing of them from man; and those things which flow from God flow first into his soul, and through his soul into the rational mind, and through this into those things which constitute the body. If any one investigates spiritual influx in any other manner, he is like one who stops up the course of a fountain and still seeks there perennial streams; or like one who deduces the origin of a tree from the root and not from the seed; or like one who examines derivations apart from their source.

[2] For the soul is not life in itself, but is a recipient of life from God, who is life in Himself; and all influx is of life, thus from God. This is meant by the statement: “Jehovah God breathed into man's nostrils the breath of lives, and man was made a living soul” (Genesis 2:7). To breathe into the nostrils the breath of lives signifies to implant the perception of good and truth. The Lord also says of Himself, “As the Father hath life in Himself so hath He also given to the Son to have life in Himself” (John 5:26): life in Himself is God; and the life of the soul is life flowing in from God.

[3] Now inasmuch as all influx is of life, and life operates by means of its receptacles, and the inmost or first of the receptacles in man is his soul, therefore in order that influx may be rightly apprehended it is necessary to begin from God, and not from an intermediate station. Were we to begin from an intermediate station, our doctrine of influx would be like a chariot without wheels, or like a ship without sails. This being the case, therefore, in the preceding articles we have treated of the sun of the spiritual world, in the midst of which is Jehovah God (5); and of the influx thence of love and wisdom, thus of life (6, 7).

[4] That life flows from God into man through the soul, and through this into his mind, that is, into its affections and thoughts, and from these into the senses, speech, and actions of the body, is because these are the things pertaining to life in successive order. For the mind is subordinate to the soul, and the body is subordinate to the mind. The mind, also, has two lives, the one of the will and the other of the understanding. The life of its will is the good of love, the derivations of which are called affections; and the life of the understanding there is the truth of wisdom, the derivations of which are called thoughts: by means of the latter and the former the mind lives. The life of the body, on the other hand, are the senses, speech, and actions: that these are derived from the soul through the mind follows from the order in which they stand, and from this they manifest themselves to a wise man without examination.

[5] The human soul, being a superior spiritual substance, receives influx directly from God; but the human mind, being an inferior spiritual substance, receives influx from God indirectly through the spiritual world; and the body, being composed of the substances of nature which are called matter, receives influx from God indirectly through the natural world.

That the good of love and the truth of wisdom flow from God into the soul of a man conjointly, that is, united into one, but that they are divided by the man in their progress, and are conjoined only with those who suffer themselves to be led by God, will be seen in the following articles.
