In Hortatives, and Pleadings, as Truth, or Disguise serveth best to the Designe in hand; so is the Judgement, or the Fancy most required.
In Demonstration, in Councell, and all rigourous search of Truth, Judgement does all; except sometimes the understanding have need to be opened by some apt similitude; and then there is so much use of Fancy. But for Metaphors, they are in this case utterly excluded. For seeing they openly professe deceipt; to admit them into Councell, or Reasoning, were manifest folly.
And in any Discourse whatsoever, if the defect of Discretion be apparent, how extravagant soever the Fancy be, the whole discourse will be taken for a signe of want of wit; and so will it never when the Discretion is manifest, though the Fancy be never so ordinary.
