Ver. 30. The strong connexions, nice dependencies,] The thought is very noble, and expressed with great beauty and philosophic exactness. The system of the universe is a combination of natural and moral fitnesses, as the human system is of body and spirit. By the strong connexions, therefore, the poet alluded to the natural part; and by the nice dependencies, to the moral. For the Essay on Man is not a system of naturalism, on the philosophy of Bolingbroke, but a system of natural religion, on the philosophy of Newton. Hence it is, that where he supposes disorders may tend to some greater good in the natural world, he supposes they may tend likewise to some greater good in the moral, as appears from these sublime images in the following lines:
If plagues and earthquakes break not heav'n's design,
Why then a Borgia or a Catiline?
Who knows, but he whose hand the lightning forms,
Who heaves old ocean, and who wings the storms,
Pours fierce ambition in a Cæsar's mind,
Or turns young Ammon loose to scourge mankind?
Ver. 35 to 42.] In these lines the poet has joined the beauty of argumentation to the sublimity of thought; where the similar instances, proposed for his adversaries' examination, show as well the absurdity of their complaints against order, as the fruitlessness of their inquiries into the arcana of the Godhead.
Ver. 41. Or ask of yonder, &c.] On these lines M. Voltaire thus descants: "Pope dit que l'homme ne peut savoir pourquoi les lunes de Jupiter sont moins grandes que Jupiter. Il se trompe en cela; c'est une erreur pardonnable. Il n'y a point de mathématicien qui n'eût fait voir," &c. And so goes on to show, like a great mathematician as he is, that it would be very inconvenient for the page to be as big as his lord and master. It is pity all this fine reasoning should proceed on a ridiculous blunder. The poet thus reproves the impious complainer of the order of Providence: You are dissatisfied with the weakness of your condition. But, in your situation, the nature of things requires just such a creature as you are: in a different situation, it might have required that you should be still weaker. And though you see not the reason of this in your own case, yet, that reasons there are, you may see in the case of other of God's creatures:
Ask of thy mother earth, why oaks are made
Taller or stronger than the weeds they shade;
Or ask of yonder argent fields above,
Why Jove's satellites are less than Jove.
Here, says the poet, the ridicule of the weeds' and the satellites' complaint, had they the faculties of speech and reasoning, would be obvious to all; because their very situation and office might have convinced them of their folly. Your folly, says the poet to his complainers, is as great, though not so evident, because the reason is more out of sight; but that a reason there is, may be demonstrated from the attributes of the Deity. This is the poet's clear and strong reasoning; from whence, we see, he was so far from saying, that man could not know the cause why Jove's satellites were less than Jove, that all the force of his reasoning turns upon this, that man did see and know it, and should from thence conclude, that there was a cause of this inferiority as well in the rational as in the material creation.
Ver. 64. Egypt's God:] Called so, because the god Apis was worshipped universally over the whole land of Egypt.
Ver. 87. Who sees with equal eye, &c.] Matt. x. 29.
Ver. 93. What future bliss, &c.] It hath been objected, that "the system of the best weakens the other natural arguments for a future state; because, if the evils which good men suffer, promote the benefit of the whole, then every thing is here in order, and nothing amiss that wants to be set right, nor has the good man any reason to expect amends, when the evils he suffered had such a tendency." To this it may be replied, 1. That the poet tells us, Ep. iv. ver. 361, that God loves from whole to parts. Therefore, if, in the beginning and progress of the moral system, the good of the whole be principally consulted, yet, on the completion of it, the good of particulars will be equally provided for. 2. The system of the best is so far from weakening those natural arguments, that it strengthens and supports them. For if those evils, to which good men are subject, be mere disorders, without any tendency to the greater good of the whole, then, though we must, indeed, conclude that they will hereafter be set right, yet this view of things, representing God as suffering disorders for no other end than to set them right, gives us too low an idea of the divine wisdom. But if those evils (according to the system of the best) contribute to the greater perfection of the whole, such a reason may be then given for their permission, as supports our idea of divine wisdom to the highest religious purposes. Then, as to the good man's hopes of retribution, these still remain in their original force: for our idea of God's justice, and how far that justice is engaged to a retribution, is exactly and invariably the same on either hypothesis. For though the system of the best supposes that the evils themselves will be fully compensated by the good they produce to the whole, yet this is so far from supposing that particulars shall suffer for a general good, that it is essential to this system, that, at the completion of things, when the whole is arrived to the state of utmost perfection, particular and universal good shall coincide;
Such is the world's great harmony, that springs
From order, union, full consent of things:
Where small and great, where weak and mighty, made
To serve, not suffer, strengthen, not invade, &c.—Ep. iii. ver. 295.
