Why has not man a
microscopic
eye?
Pope - Essay on Man
As much that end a constant course requires
Of showers and sunshine, as of man's desires;
As much eternal springs and cloudless skies,
As men for ever temperate, calm, and wise.
If plagues or earthquakes break not Heaven's design,
Why then a Borgia, or a Catiline?
Who knows but He, whose hand the lightning forms,
Who heaves old ocean, and who wings the storms;
Pours fierce ambition in a Caesar's mind,
Or turns young Ammon loose to scourge mankind?
From pride, from pride, our very reasoning springs;
Account for moral, as for natural things:
Why charge we heaven in those, in these acquit?
In both, to reason right is to submit.
Better for us, perhaps, it might appear,
Were there all harmony, all virtue here;
That never air or ocean felt the wind;
That never passion discomposed the mind.
But all subsists by elemental strife;
And passions are the elements of life.
The general order, since the whole began,
Is kept in nature, and is kept in man.
VI. What would this man? Now upward will he soar,
And little less than angel, would be more;
Now looking downwards, just as grieved 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 powers of all?
Nature to these, without profusion, kind,
The proper organs, proper powers assigned;
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 Heaven unkind to man, and man alone?
Shall he alone, whom rational we call,
Be pleased with nothing, if not blessed with all?
The bliss of man (could pride that blessing find)
Is not to act or think beyond mankind;
No powers 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 given,
To inspect a mite, not comprehend the heaven?
Or touch, if tremblingly alive all o'er,
To smart and agonize at every pore?
Or quick effluvia darting through the brain,
Die of a rose in aromatic pain?
If Nature thundered in his opening ears,
And stunned him with the music of the spheres,
How would he wish that Heaven had left him still
The whispering zephyr, and the purling rill?
Who finds not Providence all good and wise,
Alike in what it gives, and what denies?
VII. Far as Creation's ample range extends,
The scale of sensual, mental powers ascends:
Mark how it mounts, to man's imperial race,
From the green myriads in the peopled grass:
What modes of sight betwixt each wide extreme,
The mole's dim curtain, and the lynx's beam:
Of smell, the headlong lioness between,
And hound sagacious on the tainted green:
Of hearing, from the life that fills the flood,
To that which warbles through the vernal wood:
The spider's touch, how exquisitely fine!
Feels at each thread, and lives along the line:
In the nice bee, what sense so subtly true
From poisonous herbs extracts the healing dew?
How instinct varies in the grovelling swine,
Compared, half-reasoning elephant, with thine!
'Twixt that, and reason, what a nice barrier,
For ever separate, yet for ever near!
Remembrance and reflection how allayed;
What thin partitions sense from thought divide:
And middle natures, how they long to join,
Yet never passed the insuperable line!
Without this just gradation, could they be
Subjected, these to those, or all to thee?
The powers of all subdued by thee alone,
Is not thy reason all these powers in one?
