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?

VIII. See, through this air, this ocean, and this earth,
All matter quick, and bursting into birth.
Above, how high, progressive life may go!
Around, how wide! how deep extend below?
Vast chain of being! which from God began,
Natures ethereal, human, angel, man,
Beast, bird, fish, insect, what no eye can see,
No glass can reach; from Infinite to thee,
From thee to nothing. On superior powers
Were we to press, inferior might on ours:
Or in the full creation leave a void,
Where, one step broken, the great scale's destroyed:
From Nature's chain whatever link you strike,
Tenth or ten thousandth, breaks the chain alike.
And, if each system in gradation roll
Alike essential to the amazing whole,
The least confusion but in one, not all
That system only, but the whole must fall.
Let earth unbalanced from her orbit fly,
Planets and suns run lawless through the sky;
Let ruling angels from their spheres be hurled,
Being on being wrecked, and world on world;
Heaven's whole foundations to their centre nod,
And nature tremble to the throne of God.
All this dread order break--for whom? for thee?
Vile worm! --Oh, madness! pride! impiety!

IX. What if the foot, ordained the dust to tread,
Or hand, to toil, aspired to be the head?
What if the head, the eye, or ear repined
To serve mere engines to the ruling mind?
Just as absurd for any part to claim
To be another, in this general frame:
Just as absurd, to mourn the tasks or pains,
The great directing Mind of All ordains.
All are but parts of one stupendous whole,
Whose body Nature is, and God the soul;
That, changed through all, and yet in all the same;
Great in the earth, as in the ethereal frame;
Warms in the sun, refreshes in the breeze,
Glows in the stars, and blossoms in the trees,
Lives through all life, extends through all extent,
Spreads undivided, operates unspent;
Breathes in our soul, informs our mortal part,
As full, as perfect, in a hair as heart:
As full, as perfect, in vile man that mourns,
As the rapt seraph that adores and burns:
To him no high, no low, no great, no small;
He fills, he bounds, connects, and equals all.

X. Cease, then, nor order imperfection name:
Our proper bliss depends on what we blame.
Know thy own point: this kind, this due degree
Of blindness, weakness, Heaven bestows on thee.
Submit.
