Pope

"Nature to all things fix'd the Limits fit,
And wisely curb'd proud Man's pretending Wit:
As on the Land while here the Ocean gains,
In other Parts it leaves wide sandy Plains;
Thus in the Soul while Memory prevails,
The solid Pow'r of Understanding fails;
Where Beams of warm Imagination play,
The Memory's soft Figures melt away.
One Science only will one Genius fit;
So vast is Art, so narrow Human Wit;
Not only bounded to peculiar Arts,
But oft in those, confin'd to single Parts.
Like Kings we lose the Conquests gain'd before,
By vain Ambition still to make them more:
Each might his sev'ral Province well command,
Wou'd all but stoop to what they understand."

Excerpt from An Essay On Criticism
"Whate'er the talents, or howe'er design'd,
We hang one jingling padlock on the mind"
