Should he employ all his Arts in deceiving,
Stretch his Invention, and quite crack his Brain,
I find such Charms, such true Joys in believing,
I'll have the pleasure, let him have the pain:
If he proves perjur'd, I shall not be cheated,
He may deceive himself, but never me;
'Tis what I look for, and shan't be defeated,
For I'm as false, and inconstant as he.
