14. Another approach: Everything to which existence may be attributed is either one with its essence or distinct from it. Thus any given man is distinct from essential man though belonging to the order Man: a soul and a soul's essence are the same- that is, in case of soul pure and unmingled- Man as type is the same as man's essence; where the thing, man, and the essence are different, the particular man may be considered as accidental; but man, the essence, cannot be so; the type, Man, has Real Being. Now if the essence of man is real, not chanced or accidental, how can we think That to be accidental which transcends the order man, author of the type, source of all being, a principle more nearly simplex than man's being or being of any kind? As we approach the simplex, accident recedes; what is utterly simplex accident never touches at all.
Further we must remember what has been already said, that where there is true being, where things have been brought to reality by that Principle- and this is true of whatsoever has determined condition within the order of sense- all that reality is brought about in virtue of something emanating from the divine. By things of determined condition I mean such as contain, inbound with their essence, the reason of their being as they are, so that, later, an observer can state the use for each of the constituent parts- why the eye, why feet of such and such a kind to such and such a being- and can recognise that the reason for the production of each organ is inherent in that particular being and that the parts exist for each other. Why feet of a certain length? Because another member is as it is: because the face is as it is, therefore the feet are what they are: in a word the mutual determinant is mutual adaptation and the reason of each of the several forms is that such is the plan of man.
Thus the essence and its reason are one and the same. The constituent parts arise from the one source not because that source has so conceived each separately but because it has produced simultaneously the plan of the thing and its existence. This therefore is author at once of the existence of things and of their reasons, both produced at the one stroke. It is in correspondence with the things of process but far more nearly archetypal and authentic and in a closer relation with the Better, their source, than they can be.
Of things carrying their causes within, none arises at hazard or without purpose; this "So it happened to be" is applicable to none. All that they have comes from The Good; the Supreme itself, then, as author of reason, of causation, and of causing essence- all certainly lying far outside of chance- must be the Principle and as it were the examplar of things, thus independent of hazard: it is, the First, the Authentic, immune from chance, from blind effect and happening: God is cause of Himself; for Himself and of Himself He is what He is, the first self, transcendently The Self.
