Thou knowest right well, o my Son, how a Thought is imperfect in two Dimensions, being separate from its Contradiction, but also constrained in its Scope, because by that Contradiction we do not (commonly) complete the Universe, save only that of its Discourse. Thus if we contrast Health with Sickness, we include in their Sphere of Union no more than one Quality that may be predicated of all Things. Furthermore, it is for the most Part not easy to find or to formulate the true Contradiction of any Thought as a positive Idea, but only as a Formal Negation in vague Terms, so that the ready Answer is but the Antithesis. Thus to "White" one putteth not the Phrase "all that which is not White", for this is void, formless, neither clear, simple, nor positive in conception; but one answereth "Black", for this hath an Image of his Significance. So the Cohesion of Antitheticals destroyeth them only in Part, and one becometh instantly conscious of the Residue that is unsatisfied or unbalanced, whose Eidolon leapeth in thy Mind with Splendour and Joy unspeakable. Let not this deceive thee, for its Existence proveth its Imperfection, and thou must call forth its Mate, and destroy them by Love, as with the former. This Method is continuous and proceedeth ever from the Gross to the Fine, and from the Particular to the General, dissolving all Things into the One Substance of Light.
