COMMENTARY ON EPISTLE IV.
The two foregoing Epistles having considered man with regard to the means (that is, in all his relations, whether as an individual, or a member of society), this last comes to consider him with regard to the end, that is, happiness. It opens with an invocation to happiness, in the manner of the ancient poets; who, when destitute of a patron god, applied to the muse; and if she was not at leisure, took up with any simple virtue next at hand, to inspire and prosper their undertakings. This was the ancient invocation, which few modern poets have had the art to imitate with any degree either of spirit or decorum: but our author has contrived to make his subservient to the method and reasoning of his philosophic composition. I will endeavour to explain so uncommon a beauty. It is to be observed, that the pagan deities had each their several names and places of abode, with some of which they were supposed to be more delighted than others, and consequently to be then most propitious when invoked by the favourite name and place. Hence we find the hymns of Homer, Orpheus, and Callimachus to be chiefly employed in reckoning up the several titles and habitations by which the patron god was known and distinguished. Our poet hath made these two circumstances serve to introduce his subject. His purpose is to write of happiness: method, therefore, requires that he first define what men mean by happiness, and this he does in the ornament of a poetic invocation, in which the several names that happiness goes by are enumerated:
Oh happiness! our being's end and aim!
Good, pleasure, ease, content! whate'er thy name.
After the definition, that which follows next is the proposition, which is, that human happiness consists not in external advantages, but in virtue. For the subject of this Epistle is to detect the false notions of happiness, and to settle and explain the true; and this the poet lays down in the next sixteen lines. Now the enumeration of the several situations where happiness is supposed to reside, is a summary of false happiness placed in externals:
Plant of celestial seed! if dropped below,
Say, in what mortal soil thou deign'st to grow?
Fair op'ning to some court's propitious shrine,
Or deep with diamonds in the flaming mine?
Twined with the wreaths Parnassian laurels yield,
Or reaped in from harvests of the field?
The six remaining lines deliver the true notion of happiness, and show that it is rightly placed in virtue, which is summed up in these two:
Fixed to no spot is happiness sincere
'Tis no where to be found, or every where.
The poet, having thus defined his terms, and laid down his proposition, proceeds to the support of his thesis, the various arguments of which make up the body of the epistle.
