Utter’d this solemn truth, that nought
E’er had existence, only thought!
What though they say, why to be sure,
If we by Fancy’s aid can CURE,
Then why not use imagination,
A cheap and simple operation?
Say nature through her works intends
All things to answer some great ends:
Thus she form’d drugs to purge and shake,
Then man, of course of those drugs to take.[79]
