What would this man? Now upward will he soar,
And little less than angel, would be more;
Now looking downwards, just as griev'd appears
To want the strength of bulls, the fur of bears.
Made for his use all creatures if he call,
Say what their use, had he the pow'rs of all?
Nature to these, without profusion, kind,
The proper organs, proper pow'rs assign'd;
Each seeming want compensated of course,
Here with degrees of swiftness, there of force;
All in exact proportion to the state;
Nothing to add, and nothing to abate.
Each beast, each insect, happy in its own:
Is Heav'n unkind to man, and man alone?
Shall he alone, whom rational we call,
Be pleas'd with nothing, if not bless'd with all?

The bliss of man (could pride that blessing find)
Is not to act or think beyond mankind;
No pow'rs of body or of soul to share,
But what his nature and his state can bear.
Why has not man a microscopic eye?
For this plain reason, man is not a fly.
Say what the use, were finer optics giv'n,
T' inspect a mite, not comprehend the heav'n?
Or touch, if tremblingly alive all o'er,
To smart and agonize at ev'ry pore?
Or quick effluvia darting through the brain,
Die of a rose in aromatic pain?
If nature thunder'd in his op'ning ears,
And stunn'd him with the music of the spheres,
How would he wish that Heav'n had left him still
The whisp'ring zephyr, and the purling rill?
Who finds not Providence all good and wise,
Alike in what it gives, and what denies?
