2463. Certain of the families of spirits thought about those things which are now written respecting incomprehensible and ineffable things, as that it cannot be seen save from externals and effects, that from such arise those which cohere in most beautiful connection and follow in order. For example [it may appear] from those things which are the externals of man, and from [his] actions that the fibers are thus disposed in most beautiful order, from so many of which an action is composed and can exist of such a sort; wherefore it was given to reply to them, that they may by no means reason concerning it whether it is so or not, unless they should see these things and be therein, yea, think therefrom: like as man cannot see how so innumerable muscles and fibers are connected, as present an action composed from a thousand things, nor can he know how a man can live in the body unless he has first inspected and become acquainted with the muscles, viscera, and many things of the interiors of the body. The case is not different as regards the wishing to reason from externals whether [more interior and inmost things] are so, when he has never seen internals, or known that there are internals, still less what their quality is. - 1748, June 30.
