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 endeavor to show:

President Edwards' 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. 2, 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 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 connection 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 connection, or a connection 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 connection, 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.

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. 2. 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, etc., 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 vilest 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.

What constitutes natural inability according to this school.

Edwards, vol. 2. 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.

This natural inability is no inability at all.
