103. l. EVERY MAN HAS AN EXTERNAL AND AN INTERNAL OF THOUGHT. By the external and the internal of thought are here meant the same as by the external and the internal man, and by these are meant the external and the internal of the will and of the understanding, for the will and the understanding constitute man; and as these both manifest themselves in the thoughts the terms the external and the internal of thought are used. Now, since it is not the body but the spirit of man that wills and understands and consequently thinks, it follows that this external and internal are the external and the internal of man's spirit. The action of the body, whether in word or in deed, is only an effect from the internal and the external of man's spirit; for the body is only an obedient instrument.
