This lecture was given to us by Dennis Carroll.

     We next proceed to the examination of the question of man's ability or inability to obey the commandments of God. This certainly must be a fundamental question in morals and religion; and as our views are upon this subject, so, if we are consistent, must be our views of God, of his moral government, and of every practical doctrine of morals and religion. This is too obvious to require proof. The question of ability has truly been a vexed question. In the discussion of it, I shall consider the elder President Edwards as the representative of the common Calvinistic view of this subject, because he has stated it more clearly than any other Calvinistic author with whom I am acquainted. When, therefore, I speak of the Edwardean doctrine of ability and inability, you will understand me to speak of the common view of Calvinistic theological writers, as stated, summed up, and defended by Edwards.

     In discussing this subject I will endeavour to show,--

     I. PRESIDENT EDWARDS'S NOTION OF NATURAL ABILITY.

     II. THAT THIS NATURAL ABILITY IS NO ABILITY AT ALL.

     III. WHAT CONSTITUTES NATURAL INABILITY ACCORDING TO THIS SCHOOL.

     IV. THAT THIS NATURAL INABILITY IS NO INABILITY AT ALL.

     V. THAT NATURAL ABILITY IS PROPERLY IDENTICAL WITH FREEDOM OR LIBERTY OF WILL.

     VI. THAT THE HUMAN WILL IS FREE, AND THEREFORE MEN ARE NATURALLY ABLE TO OBEY GOD.

     I. I am to show what is President Edwards's notion of natural ability.

     Edwards considers freedom and ability as identical. He defines freedom or liberty to consist in "the power, opportunity, or advantage, that any one has, to do as he pleases." "Or, in other words, his being free from hindrance or impediment in the way of doing or conducting in any respect as he wills."--Works, vol. ii., page 38.

     Again, page 39, he says, "One thing more I should observe concerning what is vulgarly called liberty; namely, that power and opportunity for one to do and conduct as he will, or according to his choice, is all that is meant by it; without taking into the meaning of the word anything of the cause of that choice; or at all considering how the person came to have such a volition; whether it was caused by some external motive, or internal habitual bias; whether it was determined by some internal antecedent volition, or whether it happened without a cause; whether it was necessarily connected with something foregoing, or not connected. Let the person come by his choice anyhow, yet, if he is able, and there is nothing in the way to hinder his pursuing and exerting his will, the man is perfectly free, according to the primary and common notion of freedom." In the preceding paragraph, he says, "There are two things contrary to what is called liberty in common speech. One is, constraint; which is a person's being necessitated to do a thing contrary to his will: the other is, restraint, which is his being hindered, and not having power to do according to his will."

     Power, ability, liberty, to do as you will, are synonymous with this writer. The foregoing quotations, with many like passages that might be quoted from the same author, show that natural liberty, or natural ability, according to him, consists in the natural and established connexion between volition and its effects. Thus he says in another place, "Men are justly said to be able to do what they can do, if they will." His definition of natural ability, or natural liberty, as he frequently calls it, wholly excludes the power to will, and includes only the power or ability to execute our volitions. Thus it is evident, that natural ability, according to him, respects external action only, and has nothing to do with willing. When there is no restraint or hindrance to the execution of volition, when there is nothing interposed to disturb and prevent the natural and established result of our volitions, there is natural ability according to this school. It should be distinctly understood, that Edwards, and those of his school, hold that choices, volitions, and all acts of will, are determined, not by the sovereign power of the agent, but are caused by the objective motive, and that there is the same connexion, or a connexion as certain and as unavoidable between motive and choice, as between any physical cause and its effect: "the difference being," according to him, "not in the nature of the connexion, but in the terms connected." Hence, according to his view, natural liberty or ability cannot consist in the power of willing or of choice, but must consist in the power to execute our choices or volitions. Consequently, this class of philosophers define free or moral agency to consist in the power to do as one wills, or power to execute one's purposes, choices, or volitions. That this is a fundamentally false definition of natural liberty or ability, and of free or moral agency, we shall see in due time. It is also plain, that the natural ability or liberty of Edwards and his school, has nothing to do with morality or immorality. Sin and holiness, as we have seen in a former lecture, are attributes of acts of will only. But this natural ability respects, as has been said, outward or muscular action only. Let this be distinctly borne in mind as we proceed.

     II. This natural ability is no ability at all.

     We know from consciousness that the will is the executive faculty, and that we can do absolutely nothing without willing. The power or ability to will is indispensable to our acting at all. If we have not the power to will, we have not power or ability to do anything. All ability or power to do resides in the will, and power to will is the necessary condition of ability to do. In morals and religion, as we shall soon see, the willing is the doing. The power to will is the condition of obligation to do. Let us hear Edwards himself upon this subject. Vol. ii. p. 156, he says, "The will itself, and not only those actions which are the effects of the will, is the proper object of precept or command. That is, such a state or acts of men's wills, are in many cases properly required of them by commands; and not only those alterations in the state of their bodies or minds that are the consequences of volition. This is most manifest; for it is the mind only that is properly and directly the subject of precepts or commands; that only being capable of receiving or perceiving commands. The motions of the body are matters of command only as they are subject to the soul, and connected with its acts. But the soul has no other faculty whereby it can, in the most direct and proper sense, consent, yield to, or comply with any command, but the faculty of the will; and it is by this faculty only that the soul can directly disobey or refuse compliance; for the very notions of consenting, yielding, accepting, complying, refusing, rejecting, &c., are, according to the meaning of terms, nothing but certain acts of will." Thus we see that Edwards himself held, that the will is the executive faculty, and that the soul can do nothing except as it wills to do it, and that for this reason a command to do is strictly a command to will. We shall see by and by, that he held also that the willing and the doing are identical, so far as moral obligation, morals, and religion are concerned. For the present, it is enough to say, whether Edwards or anybody else ever held it or not, that it is absurd and sheer nonsense to talk of an ability to do when there is no ability to will. Every one knows with intuitive certainty that he has no ability to do what he is unable to will to do. It is, therefore, the veriest folly to talk of a natural ability to do anything whatever, when we exclude from this ability the power to will. If there is no ability to will, there is, and can be no ability to do; therefore the natural ability of the Edwardean school is no ability at all.

     Let it be distinctly understood, that whatever Edwards held in respect to the ability of man to do, ability to will entered not at all into his idea and definition of natural ability or liberty. But according to him, natural ability respects only the connection that is established by a law of nature between volition and its sequents, excluding altogether the inquiry how the volition comes to exist. This the foregoing quotations abundantly show. Let the impression, then, be distinct, that the Edwardean natural ability is no ability at all, and nothing but an empty name, a metaphysico-theological fiction.

     III. What constitutes natural inability according to this school.

     Edwards, vol. ii. p. 35, says, "We are said to be naturally unable to do a thing when we cannot do it if we will, because what is most commonly called nature, does not allow of it; or because of some impeding defect or obstacle that is extrinsic to the will; either in the faculty of understanding, constitution of body, or external objects." This quotation, together with much that might be quoted from this author to the same effect, shows that natural inability, according to him, consists in a want of power to execute our volitions. In the absence of power to do as we will, if the willing exists and the effect does not follow, it is only because we are unable to do as we will, and this is natural inability. We are naturally unable, according to him, to do what does not follow by a natural law from our volitions. If I will to move my arm, and the muscles do not obey volition, I am naturally unable to move my arm. So with anything else. Here let it be distinctly observed, that natural inability, as well as natural ability, respects and belongs only to outward action or doing. It has nothing to do with ability to will. Whatever Edwards held respecting ability to will, which will be shown in its proper place, I wish it to be distinctly understood that his natural inability had nothing to do with willing, but only with the effects of willing. When the natural effect of willing does not follow volition, its cause, here is a proper natural inability.

     IV. This natural inability is no inability at all.

     By this is intended that, so far as morals and religion are concerned, the willing is the doing, and therefore where the willing actually takes place, the real thing required or prohibited is already done. Let us hear Edwards upon this subject. Vol. ii. p. 164, he says, "If the will fully complies and the proposed effect does not prove, according to the laws of nature, to be connected with his volition, the man is perfectly excused; he has a natural inability to the thing required. For the will itself, as has been observed, is all that can be directly and immediately required by command, and other things only indirectly, as connected with the will. If, therefore, there be a full compliance of will, the person has done his duty; and if other things do not prove to be connected with his volition, that is not criminally owing to him." Here, then, it is manifest, that the Edwardean notions of natural ability and inability have no connection with moral law or moral government, and, of course, with morals and religion. That the Bible everywhere accounts the willing as the deed, is most manifest. Both as it respects sin and holiness, if the required or prohibited act of the will takes place, the moral law and the lawgiver regard the deed as having been done, or the sin committed, whatever impediment may have prevented the natural effect from following. Here, then, let it be distinctly understood and remembered that Edwards's natural inability is, so far as morals and religion are concerned, no inability at all. An inability to execute our volitions, is in no case an inability to do our whole duty, since moral obligation, and of course, duty, respect strictly only acts of will. A natural inability must consist, as we shall see, in an inability to will. It is truly amazing that Edwards could have written the paragraph just quoted, and others to the same effect, without perceiving the fallacy and absurdity of his speculation--without seeing that the ability or inability about which he was writing, had no connection with morals or religion. How could he insist so largely that moral obligation respects acts of will only, and yet spend so much time in writing about an ability or inability to comply with moral obligation that respects outward action exclusively? This, on the face of it, was wholly irrelevant to the subject of morals and religion, upon which subjects he was professedly writing.

     V. Natural ability is identical with freedom or liberty of will.

     It has been, I trust, abundantly shown in a former lecture, and is admitted and insisted on by Edwards,--

     1. That moral obligation respects strictly only acts of will.

     2. That the whole of moral obligation resolves itself into an obligation to be disinterestedly benevolent, that is, to will the highest good of being for its own sake.

     3. That willing is the doing required by the true spirit of the moral law.

     Ability, therefore, to will in accordance with the moral law, must be natural ability to obey God. But,--

     4. This is and must be the only proper freedom of the will, so far as morals and religion, or so far as moral law is concerned. That must constitute true liberty of will that consists in the ability or power to will, either in accordance with, or in opposition to the requirements of moral law. Or in other words, true freedom or liberty of will must consist in the power or ability to will in every instance either in accordance with, or in opposition to, moral obligation. Observe, moral obligation respects acts of will. What freedom or liberty of will can there be in relation to moral obligation, unless the will or the agent has power or ability to act in conformity with moral obligation? To talk of a man's being free to will, or having liberty to will, when he has not the power or ability, is to talk nonsense. Edwards himself holds that ability to do, is indispensable to liberty to do. But if ability to do be a sine quà non of liberty to do, must not the same be true of willing? that is, must not ability to will be essential to liberty to will? Natural ability and natural liberty to will, must then be identical. Let this be distinctly remembered, since many have scouted the doctrine of natural ability to obey God, who have nevertheless been great sticklers for the freedom of the will. In this they are greatly inconsistent. This ability is called a natural ability, because it belongs to man as a moral agent, in such a sense that without it he could not be a proper subject of command, of reward or punishment. That is, without this liberty or ability he could not be a moral agent, and a proper subject of moral government. He must then either possess this power in himself as essential to his own nature, or must possess power, or be able to avail himself of power to will in every instance in accordance with moral obligation. Whatever he can do, he can do only by willing; he must therefore either possess the power in himself directly to will as God commands, or he must be able by willing it to avail himself of power, and to make himself willing. If he has power by nature to will directly as God requires, or by willing to avail himself of power, so to will, he is naturally free and able to obey the commandments of God. Then let it be borne distinctly in mind, that natural ability, about which so much has been said, is nothing more nor less than the freedom or liberty of the will of a moral agent. No man knows what he says or whereof he affirms, who holds to the one and denies the other, for they are truly and properly identical.

     VI. The human will is free, therefore men have power or ability to do all their duty.

     1. The moral government of God everywhere assumes and implies the liberty of the human will, and the natural ability of men to obey God.

     Every command, every threatening, every expostulation and denunciation in the Bible implies and assumes this. Nor does the Bible do violence to the human intelligence in this assumption; for,--

     2. The human mind necessarily assumes the freedom of the human will as a first truth of reason.

     First truths of reason, let it be remembered, are those that are necessarily assumed by every moral agent. They are assumed always and necessarily by a law of the intelligence, although they may seldom be the direct objects of thought or attention. It is a universal law of the intelligence, to assume the truths of causality, the existence and the infinity of space, the existence and infinity of duration, and many other truths. These assumptions every moral agent always and necessarily takes with him, whether these things are matters of attention or not. And even should he deny any one or all of the first truths of reason, he knows them to be true notwithstanding, and cannot but assume their truth in all his practical judgments. Thus, should any one deny the law and the doctrine of causality, as some in theory have done, he knows, and cannot but know,--he assumes, and cannot but assume, its truth at every moment. Without this assumption he could not so much as intend, or think of doing, or of any one else doing anything whatever. But a great part of his time, he may not, and does not, make this law a distinct object of thought or attention. Nor is he directly conscious of the assumption that there is such a law. He acts always upon the assumption, and a great part of his time is insensible of it. His whole activity is only the exercise of his own causality, and a practical acknowledgment of the truth, which in theory he may deny. Now just so it is with the freedom of the will, and with natural ability. Did we not assume our own liberty and ability, we should never think of attempting to do anything. We should not so much as think of moral obligation, either as it respects ourselves or others, unless we assumed the liberty of the human will. In all our judgments respecting our own moral character and that of others, we always and necessarily assume the liberty of the human will, or natural ability to obey God. Although we may not be distinctly conscious of this assumption, though we may seldom make the liberty of the human will the subject of direct thought or attention, and even though we may deny its reality, and strenuously endeavour to maintain the opposite, we, nevertheless, in this very denial and endeavour, assume that we are free. This truth never was, and never can be rejected in our practical judgments. All men assume it. All men must assume it. Whenever they choose in one direction, they always assume, whether conscious of the assumption or not, and cannot but assume, that they have power to will in the opposite direction. Did they not assume this, such a thing as election between two ways or objects would not be, and could not be so much as thought of. The very ideas of right and wrong, of the praise and blameworthiness of human beings, imply the assumption on the part of those who have these ideas, of the universal freedom of the human will, or of the natural ability of men as moral agents to obey God. Were not this assumption in the mind, it were impossible from its own nature and laws that it should affirm moral obligation, right or wrong, praise or blameworthiness of men. I know that philosophers and theologians have in theory denied the doctrine of natural ability or liberty, in the sense in which I have defined it; and I know, too, that with all their theorizing, they did assume, in common with all other men, that man is free in the sense that he has liberty or power to will as God commands. I know that, but for this assumption, the human mind could no more predicate praise or blameworthiness, right or wrong of man, than it could of the motions of a windmill. Men have often made the assumption in question without being aware of it, have affirmed right and wrong of human willing without seeing and understanding the conditions of this affirmation. But the fact is, that in all cases the assumption has laid deep in the mind as a first truth of reason, that men are free in the sense of being naturally able to obey God: and this assumption is a necessary condition of the affirmation that moral character belongs to man.
