Some have at first for Wits, then Poets past,
Turn'd Criticks next, and prov'd plain Fools at last;
Some neither can for Wits nor Criticks pass,
As heavy Mules are neither Horse or Ass.
Those half-learn'd Witlings, num'rous in our Isle,
As half-form'd Insects on the Banks of Nile:
Unfinish'd Things, one knows now what to call,
Their Generation's so equivocal:
To tell 'em, wou'd a hundred Tongues require,
Or one vain Wit's, that might a hundred tire.
- Alexander Pope's Essay on Criticism
