Songs of Innocence and of Experience
This was Blake's way to deal with dualism. The contraries did not represent a duality but the synthesis of a higher unity. Refusing to accept this unity was the negation which destroyed the contraries because neither could exist without the other. If a contrary were labeled Good, the other contrary would have to be labeled Evil. This labeling to Blake was eating of the Tree of Knowledge of Good and Evil, and this was what continually separated man form God. Unless a man discards his proclivity to think in terms of Good and Evil in favor of thinking of Error and Truth, he loses his perception of the infinite, eternal nature of God. Error can and should be annihilated. Evil is the shadow side of Good and will be eliminated when it is overcome by Good - that is when Good has expanded until Evil is imperceptible. When all that can be learned from the contraries has been learned, they will be seen as a unity with many dimensions.
We are not forced to choose between the law and the gospel, between wrath and pity, between justice and mercy, between woe and joy or between any two dichotomies. If we see both as contributing to a higher truth we are not fooled by the 'cloven fiction.
THE GATES of PARADISE, For The Sexes, Keys, (E 268) "5 Blind in Fire with shield & spear Two Horn'd Reasoning Cloven Fiction In Doubt which is Self contradiction A dark Hermaphrodite We stood Rational Truth Root of Evil & Good Round me flew the Flaming Sword Round her snowy Whirlwinds roard Freezing her Veil the Mundane Shell 6 I rent the Veil where the Dead dwell When weary Man enters his Cave He meets his Saviour in the Grave Some find a Female Garment there And some a Male, woven with care Lest the Sexual Garments sweet Should grow a devouring Winding sheet 7 One Dies! Alas! the Living & Dead One is slain & One is fled 8 In Vain-glory hatcht & nurst By double Spectres Self Accurst My Son! my Son! thou treatest me But as I have instructed thee" Jerusalem, Plate 40 , (E 142) "All that can be annihilated must be annihilated That the Children of Jerusalem may be saved from slavery There is a Negation, & there is a Contrary The Negation must be destroyd to redeem the Contraries The Negation is the Spectre; the Reasoning Power in Man This is a false Body: an Incrustation over my Immortal Spirit; a Selfhood, which must be put off & annihilated alway To cleanse the Face of my Spirit by Self-examination."
 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
 The young man saith unto him, All these things have I kept from my youth up: what lack I yet?
 Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.
