to Plato, they are constitutive likewise, and one in essence with the power and life of nature;--[Greek: hen log'o z'oae aen, kai hae z'oae haen to ph'os t'on anthr'op'on]. And this I assert, was the philosophy of the mythic poets, who, like Æschylus, adapted the secret doctrines of the mysteries as the (not always safely disguised) antidote to the debasing influences of the religion of the state. But to return and conclude this preliminary explanation. We have only to substitute the term will, and the term constitutive power, for _nomos_ or law, and the process is the same. Permit me to represent the identity or 'prothesis' by the letter Z and the 'thesis' and 'antithesis' by X and Y respectively. Then I say X by not being Y, but in consequence of being the correlative opposite of Y, is will; and Y, by not being X, but the correlative and opposite of X, is nature,--'natura naturans', [Greek: no_mos physiko_s]. Hence we may see the necessity of contemplating the idea now as identical with the reason, and now as one with the will, and now as both in one, in which last case I shall, for convenience sake, employ the term 'Nous', the rational will, the practical reason. We are now out of the holy jungle of transcendental mataphysics; if indeed, the reader's patience shall have had strength and persistency enough to allow me to exclaim-- Ivimus ambo Per densas umbras: at tenet umbra Deum. Not that I regard the foregoing as articles of faith, or as all true;--I have implied the contrary by contrasting it with, at least, by shewing its disparateness from, the Mosaic, which, 'bona fide', I do regard as the truth. But I believe there is much, and profound, truth in it, 'supra captum [Greek: psilosoph'on], qui non agnoscunt divinum, ideoque nec naturam, nisi nomine, agnoscunt; sed res cunctas ex sensuali corporeo cogitant, quibus hac ex causa interiora clausa manent, et simul cum illis exteriora quæ proxima interioribus sunt'! And with no less confidence do I believe that the positions above given, true or false, are contained in the Promethean 'mythus'.
