"In Jewish mysticism we often come upon the view that in this world neither good nor evil exists in purity, and that their is no good without the admixture of evil nor evil without the admixture of good. The confusion of good and evil is the central problem of history and the ultimate issue of redemption...All of history is a sphere where good is mixed with evil. The supreme task of man, his share in redeeming the work of creation, consists in an effort to separate good from evil and evil from good. Since evil can only exist parasitically on good, it will cease to be when that separation will be accomplished. Redemption, therefore, is contingent upon the separation of good and evil."
