Selections from Jerusalem[The Reasoning Power]
(Jerusalem, f. 10, ll. 7–16.)

They take the Two Contraries which are call’d Qualities, with which
Every Substance is clothèd; they name them Good and Evil.
From them they make an Abstract, which is a Negation
Not only of the Substance from which it is derivèd,
A murderer of its own Body, but also a murderer
Of every Divine Member. It is the Reasoning Power,
An Abstract objecting power, that negatives everything.
This is the Spectre of Man, the Holy Reasoning Power,
And in its Holiness is closèd the Abomination of Desolation!
