Ver. 147. Reason itself, &c.] The Poet, in some other of his epistles, gives examples of the doctrines and precepts here delivered. Thus, in that Of the Use of Riches, he has illustrated this truth in the character of Cotta:
Old Cotta shamed his fortune and his birth,
Yet was not Cotta void of wit or worth.
What though (the use of barb'rous spits forgot)
His kitchen vied in coolness with his grot?
If Cotta lived on pulse, it was no more
Than bramins, saints, and sages did before.
Ver. 149. We, wretched subjects, &c.] St. Paul himself did not choose to employ other arguments, when disposed to give us the highest idea of the usefulness of christianity (Rom. vii.) But it may be, the poet finds a remedy in natural religion. Far from it. He here leaves reason unrelieved. What is this, then, but an intimation that we ought to seek for a cure in that religion, which only dares profess to give it?
Ver. 163. 'Tis hers to rectify, &c.] The meaning of this precept is, That as the ruling passion is implanted by nature, it is reason's office to regulate, direct, and restrain, but not to overthrow it. To reform the passion of avarice, for instance, into a parsimonious dispensation of the public revenues: to direct the passion of love, whose object is worth and beauty,
To the first good, first perfect, and first fair,
the το καλον τ' αγαθον, as his master Plato advises; and to restrain spleen to a contempt and hatred of vice. This is what the poet meant, and what every unprejudiced man could not but see he must needs mean, by rectifying the master passion, though he had not confined us to this sense, in the reason he gives of his precept in these words:
A mightier pow'r the strong direction sends,
And several men impels to several ends;
for what ends are they which God impels to, but the ends of virtue?
Ver. 175. Th' eternal art, &c.] The author has, throughout these epistles, explained his meaning to be that vice is, in its own nature, the greatest of evils, and produced through the abuse of man's free will:
What makes all physical and moral ill?
There deviates nature, and here wanders will:
