Of physical evil, or suffering, Pope notices only "plagues, earthquakes, and tempests," which he justifies by the remark that God "acts not by partial, but by general laws."[815] Bolingbroke gave the same explanation. Either, he said, such visitations are "rational chastisements," or they are "the mere effects, natural though contingent, of matter and motion in a material system, put into motion under certain general laws."[816] Individuals, that is, must suffer that the laws of matter may not be infringed. Leibnitz rejected the principle. "That which is an evil," he said, "for me would not cease to be an evil because it would be good for some one else. The good which pervades the universe consists, among other things, in this, that the general good is the particular good of every one who loves the author of all good." So, he says again, "we suffer often from the misdeeds of others, but when we have no share in the crime we may hold it for certain that the sufferings procure us a greater happiness."[817] The system of Pope subordinates moral agents to physical, and he finds it a sufficient vindication that the mechanical law is general, and the injury to men only occasional. Whatever may be the worth of particular persons, he believes that they are properly sacrificed to the regularity of material laws, which roll on with undistinguishing, terrific might, crushing any thinking, sentient, virtuous being who may happen to cross their path. He supposes, nevertheless, that these unbending, undiscerning laws have undergone a "change," and, what is singular, the alteration has been from better to worse, whereby he accounts for a portion of the prevalent physical evil.[818] Another portion he at one time ascribed to "chance," which had intruded itself into the arrangements of the Almighty, and overruled his designs.[819] The optimism which represented man to be the sport of mechanical laws, of deteriorating changes in the physical system, and of blind, ungovernable chance, was not an optimism to clear away difficulties, and silence objections.

Metaphysical evil, or the limitation of endowments, is inevitable in every being below the Godhead, and Pope contends that the best system must manifestly consist in an infinite series of creatures, from the greatest to the least. The notion is found in Locke and Leibnitz. There are beings, said the latter, above and below us, or there would be a void in the order of species.[820] The idea was more fully developed by Archbishop King, and is simply an extension to the universe of the terrestrial system, where a gradation of beings on a connected plan is the law. Pope carried the principle to extravagance. He contends that the omission of the smallest creature would break the chain, would throw the universe into confusion, and involve all creation in a common ruin.[821] To keep the universe from tumbling to pieces, "it is plain," according to him, that "there must be somewhere such a rank as man,"[822] and the rule holds equally of the minutest animalcule on the globe. There is a flaw in his premises. It is not apparent that the extinction of the flea would upset the universe, nor that the scale of beings must necessarily be the same which at present prevails. The facts are against the "must be" of Pope. There was a time when other creatures were, and man was not, and when animated nature was able to dispense with the human race. Infinite wisdom must form the best possible system and a gradation of beings, which now includes man, is an actual part of the scheme. Pope's argument breaks down when, to justify the creation of man, he supposes that a chain of beings and an orderly universe could not have existed unless man had been a link in the series. His argument is equally weak when he maintains that the infinite wisdom of God is a guarantee that there will not be a gap in the endless chain of existences, but that it is a question whether infinite wisdom may not have made a mistake with respect to man's proper place in the series, and erred in the after sorting of the gradations which it had previously conceived and created on an infallible plan.[823] The poet was inconsistent to childishness. Johnson believed that when Pope talked of man's place he did not attach any meaning to the term. The words would seem to imply that it was a question whether man was placed in the circumstances which were best adapted to his moral, mental, and physical nature. But if Pope had thoroughly comprehended his borrowed phrases, he would not have proposed the enquiry under a form which stultified his premises.

There were errors enough in Pope's doctrine without the misinterpretations of Voltaire, who has falsified the views of the poet, as he had previously misstated the profounder system of Leibnitz. "Those," says Voltaire, "who exclaim that all is good are charlatans. Shaftesbury, who brought the fable into fashion, was a very unhappy man. I have seen Bolingbroke devoured with chagrin and rage, and Pope, whom he induced to put the mockery into verse, was as much to be pitied as any man I have ever known,—deformed in body, unequal in his temper, always ill, a burthen to himself, and harassed by a hundred enemies to his dying hour. Quote me at least some happy men who say that all is good. Any one who had seen the beautiful Ann Boleyn, and the still more beautiful Mary Stuart, in their youth, would have said that is good, but would he have said it when he saw them perish by the hand of the executioner? would he have said it when he saw the grandson of the beautiful Mary die the same death in the midst of his capital? would he have said it when he saw the great-grandson more unfortunate still, since he lived longer?"[824] Pope, in his imperfect theory, did not deny the existence of sorrow, but asserted, or implied, that the sorrow was an advantage either to the sufferer or others. Voltaire looked singly at the misery without heeding the gain. Mary Queen of Scots at the block was superior to the radiant beauty who was starting on a profligate career. Charles I., penitent for his murderous abandonment of Strafford, and, perhaps, for his creed that duplicity is a virtue when employed by kings to circumvent subjects, was a vastly better man on the scaffold than on the throne. James II. was in a more advantageous position with the inducement to repentance which his long exile supplied than if he had succeeded in his fraudulent attempts to subvert the English church and constitution. The rage of Bolingbroke, and Pope's fretful temper, were certainly inexplicable on the pretence that they were poured into the mind by the Deity. They did not militate against the truer optimism which saw in them self-imposed vice and pain, rendered possible by the free-will which is a privilege to mankind.

Pope filled up the outline of his system with declamatory invectives against objectors, and with reflections intended to prove that the imperfections of man befitted his position in the universe. There is little force in the poet's reasoning. He passes over difficulties, and replies to cavils which no one worth answering ever urged. Some of his remarks are obscure, some erroneous, some common-place. Such as they are they have not been woven into a consecutive argument. M. Crousaz says he knew persons who were persuaded that Pope had tacked together a number of fragments he had composed at different times, before he had the idea of an Essay on Man, which was a contrivance to work up his collection of odds and ends. He understood, in fact, little beyond the separate thoughts, and was insensible to the want of coherence, consistency and purpose. It would be lost labour to search, like Warburton, for a strength and closeness of reasoning which were not in the mind of the author.

The second epistle treats of man "with respect to himself as an individual." The Bible is a revelation of God, and a perpetual summons to mankind "to know and understand" him. "Thus saith the Lord, Let not the wise man glory in his wisdom, but let him that glorieth glory in this, that he understandeth and knoweth me."[825] The divinity at last descended upon earth, and lived our life, acting and speaking under our circumstances, that God might be clearly manifested to the world. "He that hath seen me," says our Lord, "hath seen the Father."[826] The divine light appeared darkness and imposture to Pope. He was even blind to the light which his natural understanding would have furnished, and, taught by Bolingbroke, he abjured all pretension to a knowledge of the Almighty under the plea of reverencing his inscrutable grandeur. Man must not venture to scan God; his only proper study is to learn to know himself.[827] This second epistle exhibits the kind of self-knowledge to which Pope attained, when, renouncing the knowledge of God, he determined to limit his investigations to man.

He draws a desolate picture. Man is in doubt whether he is a god or a beast; whether he ought to prefer his body or his mind. He is a confused chaos of thought and passion, he reasons only to err, and is only born to die.[828] The general incapacity, we are told, extended to Newton, and it might have occurred to the poet that it was a useless task to study our nature when the deductions of reason in its highest estate are uniformly wrong. He committed the oversight from his habit of borrowing fragments he was not at the pains to understand. His caricature was a partial and distorted copy from Pascal, who with wonderful energy of language, amplified the helplessness of fallen man that he might insist the more strongly on the necessity of his restoration through the Gospel. He overcharged the evil to exalt the remedy. Pope had not any remedy to suggest. He leaves the "confused chaos" in its primitive impotence, and calls upon mankind to embark in a deceptive study, with the warning that they will wander from error to error.

Without tying Pope down to the rhetorical exaggerations in the opening paragraph of his second epistle, we find from a passage in the first epistle that he reduced to insignificance the self-knowledge attainable by mankind. He said that when the proud horse and dull ox knew why man put them to this use or that, then would proud and dull man comprehend the end and use of his being, passions, sufferings, and actions.[829] The amount of knowledge possessed by the horse and ox is not discoverable by us. The only nature adequately known to man is his own, and his nature reveals his end. The ideas which ought to govern him proceed from his Maker. They are the voice of God speaking to him, and telling him the purpose for which he lives. He learns, above all, that he is the servant of the Almighty, that his passions are to be ruled by his conscience, that duty is supreme, that his sufferings are the discipline to perfect his character, that earth is the school for a higher existence. He may be negligent and perverse; he may refuse to look into his nature, and may, in part, defy it; may thence arrive at false conclusions, and adopt a false course of conduct, which are the abuses of a free-will that can sink or soar, but the grand outlines of his nature are plain to every honest and earnest enquirer, and blank ignorance on the end of his being, passions, sufferings, and actions is not the inevitable condition of man.

The conviction that we are ignorant of the use of our being and actions did not keep Pope from acknowledging that "good" is the end to which we aspire.[830] The nature of this good, and the means of obtaining it, is the main subject of the second epistle, "which contains," says Warburton, "the truest, clearest, shortest, and consequently the best system of ethics that is anywhere to be met with."[831] The system which Warburton thought "true and clear" appears to be eminently false and contradictory.

Man has certain implanted tendencies, physical, intellectual, and sympathetic,—the craving for food, for knowledge, for society, etc. None of our primitive endowments can be termed moral, since they are bestowed upon us independently of our will, and it is not till will interposes that morality begins, but in their purity they are all advantageous, and many of them are directed to the identical end which morality prescribes. They are part of the stock-in-trade with which man starts in his career, and he is charged with the wise administration of them. A brief experience teaches him that an instinctive tendency may be carried to excess. His craving for food and drink may turn to gluttony and drunkenness; his passion for knowledge may convert him into a solitary student without any care for his kind; his love of society and affection may unfit him for the business and drudgery of life. Or he may yield to a propensity till satiety succeeds, and he is left listless and jaded. Or he may indulge a lawful propensity by lawless methods. Or he may be hurried away by successive impulses, and be too unstable to put his gifts to a profitable use. In any of these ways his proper nature becomes mutilated and degraded. His reason informs him that to enjoy the full advantage of his tendencies he must not consent to be drifted along by the current which is strongest for the moment. He must curb the lower propensities, and foster the higher; he must regulate the several unities in a manner to derive the greatest benefit from the whole; he must substitute for the reign of impulse what moralists call his interest well understood. He does not stop at self-interest. He rises above his personal good into the impersonal sphere of good in itself. He perceives that there is a law superior to his individual interests, a law of universal obligation, and which is immutable and eternal.

Of these three motives, the instinctive, the prudential, and the law of independent morality, Pope rejects the last. He believes that self is the single spring of action in men, and he seriously adopts the old sarcastic saying, "Every man for himself, and God for us all."[832] He divides this selfish nature into two parts,—self-love, which designates the impulsive propensities, and reason, which governs them on the behalf of interest well-understood.[833] Already there is an inconsistency in his phraseology when he puts self-love in direct opposition to reason. Reason in his theory is simply the selfishness of calculation; self-love the selfishness of impulse. Self-love is absolute in both, and is not the less self-love because we deliberate upon the means which are best adapted to secure the selfish end.
