The Interaction of the Soul with the Body

Selection from Emanuel Swedenborg's Spiritual Diary
CONCERNING THE INTERACTION OF THE SOUL WITH THE BODY

Nothing can be known concerning the interaction of the soul, unless it is known what the soul is. It is impossible to speak of the interaction of something known, as is the body, with a thing entirely unknown as to all its quality. Who, at this day, knows anything as to what the soul is? Do not some regard it as a flaming something? some as an ethereal something? others a thinking something, [existing] in some such way as in a subject? others as a pure thinking something, without a substantial form by which [to exist]? What manner of opinion is held concerning the soul, is plainly manifest from this, that they assign it a seat in some part of the body: some in the heart, some in some part of the head, in the corpus striatum in the stomach, in the striated substance, yea, in the little pineal gland! Yea, indeed, from this it is plain, that, at this day, it is entirely unknown what the soul is, since [men] believe that, after death, it remains indeed, but is kept in a certain somewhere (Pu) till the judgment-day. If it should be asked whether it has any form, it is feared to reply thereto consequently, [they believe], also, that it has no quality.

Since, therefore, the soul is such an unknown thing, it is not wonderful that there cannot be known anything concerning its state, and concerning influx, and concerning interaction - as it is called.

As respects the soul, concerning which it is said that it lives after death, it is no other than the man himself, who lives in the body, thus the purer part of the man, which is conjoined with the body, so that, by means of the body, it may perform the functions it ought, in the world. From this the body lives. This, after death, is called a spirit. It likewise appears, then, entirely in a human form; it has the senses, to wit, touch, smell, sight, and hearing, much more exquisitely than in the world. It has appetites, cravings, desires, affections, loves, similar to those which [it had] in the world, but in a less coarse state. It then thinks, as in the world, but more clearly; speaks with others, and is in society; and, this being the case, if [the spirit] does not reflect upon the fact that he is in another life, he knows no otherwise than that he is in the world - as I have heard on several occasions. This is the soul of man; and, because that is the interior man, to whose service was formed the body, which, in the world, is supposed to be, and is called, the man, the interiors of this, also, relate to man, as may be evident from the angels. These are in interiors, and appear in like manner as men do, which is also known from the Word, when they appeared to men. Thence at least, it is evident, that the angelic form is the human form.

The reason that souls appear in the human form, is, because the universal heaven does not conspire to another form, and because, in heaven, the case is such, that the universal heaven acts into the least particulars there, and the least particulars into the universal [heaven]; hence it can never be otherwise than that everyone there, whether angel or spirit, is in the form of a man.

From these things it is now plain what the soul is; and, inasmuch as, respecting the quality of the soul, and what it is, man is entirely ignorant in his thought, it is preferable that it should not be named soul, but, instead thereof, spirit, since this is the soul of man which lives after death; or, if you prefer, instead of spirit, let it be called the interior man; for it is the man himself, which lives. That the matter is so circumstanced, I ought to know thoroughly, from an eight to nine years almost constant association with spirits and angels
