No More Learning

There's some peculiar in each leaf and grain,
Some unmarked fibre, or some varying vein:
Shall only man be taken in the gross?
Grant but as many sorts of mind as moss.
That each from other differs, first confess;
Next, that he varies from himself no less:
Add Nature's, custom's reason's passion's strife,
And all opinion's colours cast on life.
Our depths who fathoms, or our shallows finds,
Quick whirls, and shifting eddies, of our minds?
On human actions reason though you can,
It may be reason, but it is not man:
His principle of action once explore,
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,
All know 'tis virtue, for he thinks them knaves:
When universal homage Umbra pays,
All see 'tis vice, and itch of vulgar praise.
When flattery glares, all hate it in a queen,
While one there is who charms us with his spleen.
But these plain characters we rarely find;
Though strong the bent, yet quick the turns of mind:
Or puzzling contraries confound the whole;
Or affectations quite reverse the soul.
The dull, flat falsehood serves for policy;
And in the cunning, truth itself's a lie:
Unthought-of frailties cheat us in the wise;
The fool lies hid in inconsistencies.
See the same man, in vigour, in the gout;
Alone, in company; in place, or out;
Early at business, and at hazard late;
Mad at a fox-chase, wise at a debate;
Drunk at a borough, civil at a ball;
Friendly at Hackney, faithless at Whitehall.
Catius is ever moral, ever grave,
Thinks who endures a knave is next a knave,
Save just at dinner--then prefers, no doubt,
A rogue with venison to a saint without.
Who would not praise Patritio's high desert,
His hand unstained, his uncorrupted heart,
His comprehensive head! all interests weighed,
All Europe saved, yet Britain not betrayed.
He thanks you not, his pride is in piquet,
Newmarket-fame, and judgment at a bet.
What made (say Montagne, or more sage Charron)
Otho a warrior, Cromwell a buffoon?
A perjured prince a leaden saint revere,
A godless regent tremble at a star?
The throne a bigot keep, a genius quit,
Faithless through piety, and duped through wit?
Europe a woman, child, or dotard rule,
And just her wisest monarch made a fool?
Know, God and Nature only are the same:
In man, the judgment shoots at flying game,
A bird of passage! gone as soon as found,
Now in the moon, perhaps, now under ground.
In vain the sage, with retrospective eye,
Would from the apparent what conclude the why,
Infer the motive from the deed, and show,
That what we chanced was what we meant to do.
Behold! if fortune or a mistress frowns,
Some plunge in business, others shave their crowns:
To ease the soul of one oppressive weight,
This quits an empire, that embroils a state:
The same adust complexion has impelled
Charles to the convent, Philip to the field.
