186. II. IN LIKE MANNER A MAN'S (_homo_) INTERNAL FORM WHICH IS THAT OF HIS SPIRIT, IS CONTINUALLY CHANGING. The reason why this form is continually changing as the state of the man's life is changed, is, because there is nothing that exists but in a form, and state induces that form; wherefore it is the same whether we say that the state of a man's life is changed, or that its form is changed. All a man's affections and thoughts are in forms, and thence from forms; for forms are their subjects. If affections and thoughts were not in subjects, which are formed, they might exist also in skulls without a brain; which would be the same thing as to suppose sight without an eye, hearing without an ear, and taste without a tongue. It is well known that there are subjects of these senses, and that these subjects are forms. The state of life, and thence the form, with a man, is continually changing; because it is a truth which the wise have taught and still teach, that there does not exist a sameness, or absolute identity of two things, still less of several; as there are not two human faces the same, and still less several: the case is similar in things successive, in that no subsequent state of life is the same as a preceding one; whence it follows, that there is a perpetual change of the state of life with every man, consequently also a perpetual change of form, especially of his internals. But as these considerations do not teach anything respecting marriages, but only prepare the way for knowledges concerning them, and since also they are mere philosophical inquiries of the understanding, which, with some persons, are difficult of apprehension, we will pass them without further discussion.
