That instant 'tis his principle no more.
Like following life through creatures you dissect,
You lose it in the moment you detect.
Yet more; the difference is as great between
The optics seeing, as the object seen.
All manners take a tincture from our own;
Or come discoloured through our passions shown.
Or fancy's beam enlarges, multiplies,
Contracts, inverts, and gives ten thousand dyes.
Nor will life's stream for observation stay,
It hurries all too fast to mark their way:
In vain sedate reflections we would make,
When half our knowledge we must snatch, not take.
Oft, in the passion's wild rotation tost,
Our spring of action to ourselves is lost:
Tired, not determined, to the last we yield,
And what comes then is master of the field.
As the last image of that troubled heap,
When sense subsides, and fancy sports in sleep
(Though past the recollection of the thought),
Becomes the stuff of which our dream is wrought:
Something as dim to our internal view,
Is thus, perhaps, the cause of most we do.
True, some are open, and to all men known;
Others so very close, they're hid from none
(So darkness strikes the sense no less than light),
Thus gracious Chandos is beloved at sight;
And every child hates Shylock, though his soul
Still sits at squat, and peeps not from its hole.
At half mankind when generous Manly raves,
