PARACELSUS is here very obscure, but he manifestly means by "the
other," the Body. To resume:

"The Souls know one another as 'I,' and 'the other.' They converse
together in their language, not by necessity according to our
thoughts, but what _they_ will. And note, too, that there may be anger
between them, and one may belittle or injure the other; this injury is
in the Soul, the Soul in the body. Then the body suffers and is ill--
not materially or from a material _Ens_, but from the Soul. For this
we need spiritual remedy. Ye are two who are dear unto one another;
great in affinity. The cause is not in the body, nor is it from
without; it comes from your souls (_Geisten_), who are allied.
The same pair may become inimical, or remain so. And that ye may
understand a cause for this, note that the Spirit (_Geist_) of the
Reasoning Faculty (_Vernunft_) is not born, save from the _Will_,
therefore the Will and the Reason are separate. What exists and acts
according to the Will lives in the Spirit; what only according to
the Reason lives against the Spirit. For the Reason brings forth no
spirit, only the Soul (_Seel_) is born of it--from Will comes the
Spirit, the essence of which we describe and let the Soul be."

In this grandly conceived but most carelessly written passage the
author, in the beginning thereof, makes such confusion in expressing
both Soul and Spirit with the one word, _Geist_, that his real meaning
could not be intelligible to the reader who had not already mastered
the theory. But, in fact, the whole conception is marvelous, and
closely agreeing with the latest discoveries in Science, while
ignoring all the old psychological system.

Very significant is what PARACELSUS declares in his _Fragmenta
