Two principles in human nature reign;
Self-love, to urge, and reason, to restrain;
Nor this a good, nor that a bad we call,
Each works its end, to move or govern all:
And to their proper operation still
Ascribe all Good, to their improper, Ill.
Self-love, the spring of motion, acts the soul;
Reason's comparing balance rules the whole.
Man, but for that, no action could attend,
And, but for this, were active to no end:
Fix'd like a plant on his peculiar spot,
To draw nutrition, propagate, and rot:
Or, meteor-like, flame lawless thro' the void,
Destroying others, by himself destroy'd.
Most strength the moving principle requires;
Active its task, it prompts, impels, inspires.
Sedate and quiet the comparing lies,
Form'd but to check, delib'rate, and advise.
Self-love, still stronger, as its objects nigh;
Reason's at distance, and in prospect lie:
That sees immediate good by present sense;
Reason, the future and the consequence.
Thicker than arguments, temptations throng,
At best more watchful this, but that more strong.
The action of the stronger to suspend
Reason still use, to reason still attend.
Attention habit and experience gains;
Each strengthens reason, and self-love restrains.
Let subtle schoolmen teach these friends to fight,
More studious to divide than to unite;
And grace and virtue, sense and reason split,
With all the rash dexterity of wit.
Wits, just like fools, at war about a name,
Have full as oft no meaning, or the same.
Self-love and reason to one end aspire,
Pain their aversion, pleasure their desire;
But greedy that, its object would devour,
This taste the honey, and not wound the flow'r:
Pleasure, or wrong or rightly understood,
Our greatest evil, or our greatest good.
Modes of self-love the passions we may call:
'Tis real good, or seeming, moves them all:
But since not ev'ry good we can divide,
And reason bids us for our own provide:
Passions, tho' selfish, if their means be fair,
List under Reason, and deserve her care;
Those, that imparted, court a nobler aim,
Exalt their kind, and take some virtue's name.
In lazy apathy let Stoics boast
Their virtue fix'd; 'tis fix'd as in a frost;
Contracted all, retiring to the breast;
But strength of mind is exercise, not rest:
The rising tempest puts in act the soul,
Parts it may ravage, but preserves the whole.
On life's vast ocean diversely we sail,
Reason the card, but passion is the gale;
Nor God alone in the still calm we find,
He mounts the storm, and walks upon the wind.
Passions, like elements, tho' born to fight,
Yet, mix'd and soften'd, in his work unite:
These 'tis enough to temper and employ;
But what composes man, can man destroy?
Suffice that reason keep to nature's road,
Subject, compound them, follow her and God.
Love, hope, and joy, fair pleasure's smiling train,
Hate, fear, and grief, the family of pain,
These mixt with art, and to due bounds confin'd,
Make and maintain the balance of the mind:
The lights and shades, whose well accorded strife
Gives all the strength and colour of our life.
