186. II. SO LIKEWISE THE INTERNAL FORM WHICH IS THAT OF HIS SPIRIT. That this is continually changing, as the state of the man's life is changing, is because there is nothing whatever that is not in a form; and state induces form. Wherefore it is the same thing whether it be said that the state of man's life is changed or that his form is changed. All man's affections and thoughts are in forms and hence from forms, forms being their subjects. Were affections and thoughts not in subjects which are formed, they might exist even in skulls devoid of brains. This would be the same as sight without an eye, hearing without an ear, and taste without a tongue. That these organs are the subjects of those senses, and that they are forms, is well known.  That with man, the state of life and consequently the form is continually changing, is because there is no such thing as the sameness or absolute identity of two things, still less of many--a truth which the wise have taught and still teach. For example, no two human faces are the same, still less many faces. It is the same in things successive, there being no such thing as the identity of a subsequent state of life with a past state. From this it follows that there is a perpetual change of the state of life with man, especially of his internal states, and consequently a perpetual change of form also. But since these considerations do not teach anything respecting marriages but only prepare the way to knowledges concerning them; and since they are only philosophical matters examined into from the understanding, and to some these are difficult of perception, therefore, with these few words, they are passed by.
