Part 10

The first argument of President Edwards is as follows. When the existence of a thing is infallibly and indissolubly connected with something else, which has already had existence, then its existence is necessary; but the future volitions of moral agents, are infallibly and indissolubly connected with the foreknowledge of God; and therefore they are necessary, p. 114-15. Now this argument is perfectly sound; the conclusion is really contained in the premise, or definition of necessity, and it is fairly deduced from it. It is as perfect as any syllogism in Euclid _but what does it prove?_ It proves that all human actions are necessary--but in what sense? Does it prove that they are necessary with a _moral necessity?_ Does it prove that they are brought to pass by the influence of moral causes? No such thing is even pretended: "I allow what Dr. Whitby says to be true," says Edwards, "that mere foreknowledge does not affect the thing known, to _make_ it more certain or future," p. 122. He admits that foreknowledge exerts "no influence on the thing known to make it necessary." He does not even pretend that there is any _moral necessity_ shown to exist by this argument; and hence his conclusion has no connexion with the great doctrine of the Inquiry, or the point in dispute. It aims at the word, but not at the thing. The infallible connexion it shows to exist, is admitted to be entirely different from the infallible connexion between moral causes and volitions; that is to say, it is admitted that it does not prove any thing to the purpose.

But is the indissoluble connexion, or necessity, established by this argument, at all inconsistent with human liberty? If it is not; and if our scheme of liberty is perfectly consistent and reconcilable with it; then it infers nothing, and is nothing, that is opposed to what we hold.

This question admits of an easy solution. The foreknowledge of a future event proves it to be necessary in precisely the same manner that the knowledge of a present event shows it to be necessary. This is conceded by Edwards. "All certain knowledge," says he, "whether it be foreknowledge, or after knowledge, or concomitant knowledge, proves the thing known now to be necessary, by some means or other; _or proves that it is impossible it should now be otherwise than true_," p. 121. And again, "All certain knowledge proves the necessity of the truth known; whether it be _before_, or _after_, or _at the same time_," p. 124; and so in other places.

In what sense then, let us inquire, does the knowledge of a present event prove it to be necessary? It is necessary, says Edwards, because it is indissolubly connected with the knowledge of it. In other words, it could not possibly be known to exist, unless it did exist; and hence, its existence is said to be indissolubly connected with the knowledge of its existence, or, in other words, it is said to be necessary. This is all true; but is this indissoluble connexion, or necessity, at all inconsistent with the contingency of the event known? _This is the question;_ and let us not lose sight of it in a mist of words. Let it be distinctly borne in mind, and it will be easily settled.

For this purpose, let us suppose, to adopt the language of President Edwards, "that nonentity is about to bring forth;" and that an event comes into being without any cause of its existence. This event then exists; it is seen, and it is known to exist. Now, even on this wild supposition, there is an infallible and indissoluble connexion between the existence of the event and the knowledge of it; and hence it is necessary, in the sense above explained. But what has this necessary connexion to do with the cause of its existence? This indissoluble connexion, this dire necessity, is perfectly consistent, as we have seen, with the supposition that the event had no cause at all of its existence. How can it conflict, then, with any scheme of free-agency that ever was dreamed of by man?

If this argument proves any thing in regard to human actions, it only proves that a volition has an effect, and not that it has a cause. Indeed, it has been said, that the knowledge of an event is the effect of its existence; and the same remark has been extended to the foreknowledge of God with respect to the future volitions of human beings. This position is not denied by Edwards; he considers, in fact, that it strengthens, rather than weakens, his argument. "Because it shows the existence of the event to be so settled and firm, that _it is as if it had already been;_ inasmuch as _in effect_ it actually exists already;" and much more to the same purpose, p.122-3. "It is as strong arguing," says he, "from the effect to the cause, as from the cause to the effect."

This is all true; it is as strong arguing from effect to cause, as it is from cause to effect. But do the arguments prove the same thing? Let us see. I know a thing to exist; and therefore it does exist. This is to reason from effect to cause. The conclusion is inevitable; but what does it prove? Why, it proves that the thing does exist--it proves the bare fact of existence. The indissoluble connexion, or the necessity, in this case, exists between the knowledge and the event known; and it has no relation to the question how the event came to exist. This argument, then, in regard to human volitions, only proves that they are indissolubly connected with their effects, and are necessarily implied by them; just as every cause is implied by its effects: but no libertarian in the world has ever questioned such a position. For all that such an argument proves, all the volitions of moral agents may come into existence, without having the least shadow of reason or ground of their existence. We admit that volitions are efficient causes; and that they have effects, with which they are indissolubly connected. Edwards undertook to show, that volitions are necessary, because they are infallibly and indissolubly connected with their causes; and he has shown that they are necessary, because they are infallibly and indissolubly connected with their effects! This is one branch of his great argument.

There is another sense, in which the knowledge of an event, whether it be _fore_, or _after_, or _concomitant_, knowledge, proves it to be necessary. This sense is not clearly distinguished from the former by Edwards. He recognizes them both, however, although he blends them together, and frequently turns from the one to the other in the course of his argument. It is highly important, and affords no little satisfaction, to keep them clearly distinct in our minds.

A thing is said to be necessary, as we have seen, because it is connected with the knowledge of it; and, if a thing does exist, or is certainly and infallibly known to exist, it may be said to be necessary, on the principle that it is impossible it should exist and not exist at one and the same time. These two things are evidently different; and, for the sake of distinctness in our language, as well as in our thoughts, I shall call the first a _logical_, and the last an _axiomatical_ necessity. A thing, then, which does exist, is said to be necessary with an _axiomatical_ necessity; because it is impossible for it not to exist while it does exist: and it is said to be necessary, with a _logical_ necessity, because it is indissolubly connected with the knowledge of it. The former kind of necessity is frequently presented in this form of expression, that if a thing does exist, it is impossible it should be otherwise than true that it does exist. In this form of expression, it is frequently resorted to by Edwards.

Thus, says he, "I observed before, in explaining the nature of necessity, that in things which are past, their past existence is now _necessary;_ having already made sure of existence, _it is now impossible that it should be otherwise than true, that the thing has existed_," p. 114-15. Just so we may say in relation to things which now exist; for, having already made sure of existence, it is impossible it should be otherwise than true, that they do now exist; or, in other words, it is impossible they should not exist while they do exist. In like manner, if the future existence of any thing is foreknown, "it is impossible it should be otherwise than true," that it should exist, or come to pass: that is to say, if it will exist, it will be impossible for it not to exist at the time of its existence.

Foreknowledge, I admit, infers this kind of necessity; but is this any thing to the purpose? The conclusion is the same, whether it be deduced from foreknowledge, or concomitant knowledge. Let us suppose, then, for the sake of clearness and convenience, that a thing is now known to exist. It follows from hence, by a _logical_ necessity, that it does exist; for it could not possibly be known to exist, unless it did exist. And, as it does exist, "it is impossible that it should be otherwise than true that it does exist;" or, in other words, it is impossible for it not to exist now, while it does exist. This is all there is in this part of the argument.

And what does it amount to? It is a simple declaration of what no body ever denied--that if a thing exists, or is to exist, or has existed, it is impossible to conceive of it as not existing at the time of its existence. All this is perfectly true, without the least reference to the question, how it came to exist, or how it will come to exist? It is wholly irrelevant to the point at issue. It controverts no position, held by any sane man that now lives, or that ever has lived.

In other words, if a thing is known to exist, certainly and infallibly, then it does exist; and if it does exist, then "it is impossible it should be otherwise than true" that it does exist; and hence its existence is said to be necessary with an _axiomatical_ necessity. But this does not prove that it is _necessarily produced_. For, supposing it to exist, its existence would be necessary in the above sense, even if it had no cause of its existence. The necessity here referred to, is a necessity _in the order of our ideas_, and not _in the course of events_. It arises from the impossibility of a thing's not existing at the time it does exist; and it has no reference whatever to the causation of any thing: it is a fundamental law of belief, and not a _causal_ necessity. These three things, an _axiomatical_, a _logical_, and a _causal_ necessity, are most strangely confounded in the argument of President Edwards.

Will it be said, that in this argument, it was not the object of Edwards, to prove that there is a moral necessity in regard to our volitions; but only that they are "not without all necessity?" Suppose this to be the case, with whom has he any controversy, or to what purpose has he argued? No one has ever held that human volitions are "without all necessity," according to Edwards' use of that term; and no one can hold it. No one can deny, that there is an indissoluble connexion between the existence of a thing, and the certain and infallible knowledge of its existence; or between the effect of a thing and the thing itself; or that it is impossible for a thing not to exist while it does exist. In these senses of the word, all rational creatures are bound to acknowledge that human volitions are necessary. The most strenuous advocate of free-agency has not one word to say against them; and such being the meaning of Edwards, we must all heartily concur with him, when he says, "that there is no geometrical theorem or proposition whatever more capable of _strict demonstration_, than that God's certain prescience of the volition of moral agents is inconsistent with such a contingency of these events, _as is without all necessity_," p. 125-6.

If it can be truly said, that a thing is foreknown, it follows that it will come to pass, or the proposition which affirms the future existence of it, is necessarily true. In other words, it is self-contradictory and absurd, to assert that a thing is foreknown, and yet that it may not come to pass; just as it is to assert that a thing is known to exist and yet at the same time does not exist. Hence, it is frequently alleged by Edwards, that to deny his conclusions, drawn from foreknowledge, is self-contradictory and absurd; unless we deny foreknowledge itself. To admit this, says he, and yet contend that the thing foreknown may possibly not be, is to fall into a plain contradiction, and "to suppose God's foreknowledge to be inconsistent with itself," p. 117. Is it not strange, that it did not occur to Edwards, that if to deny his position is to deny that God foreknows what he foreknows; then to affirm it, is only to affirm that he foreknows what he foreknows? Indeed, all those reasonings in which he represents the denial of his position as self-contradictory and absurd, should have convinced him that he could prove nothing to the purpose, by arguing from the foreknowledge of God, or else he must assume the very thing in dispute, by taking it for granted that it is future; or, which is the same thing in effect, that it is foreknown. For in admitting any premise, we admit, no more than is contained in it; and if we only deny what is not contained in our admission, we are not involved in a self-contradiction, or absurdity. In alleging that we have done this, therefore, in the present case;--in alleging that we contradict ourselves by admitting the foreknowledge of God, and in denying necessity, he takes it for granted that the very thing in dispute is included in that foreknowledge. In other words, if Edwards does not mean to say, that the point in dispute is included in the foreknowledge of God; then he cannot say, that we contradict ourselves by admitting that divine prescience; and if he does mean to say, that the thing which we deny is included in the foreknowledge of God, then he begs the question.

It is freely conceded, that whatever God foreknows will most certainly and infallibly come to pass. He foresees all human volitions; and, therefore, they will most certainly and infallibly come to pass, in some manner or other: the bare fact of their future existence is clearly established by God's foreknowledge of them. And if all human volitions will be brought to pass, by the operation of moral causes; then this manner of their existence is foreknown to God, and will all come to pass in this way; but to take this for granted, is to beg the question. We have just as much right to suppose, that God foreknows that the volitions of moral agents are not necessitated, as the necessitarian has to suppose that He foreknows the contrary; and then it would follow that our volitions are necessarily free, or without any producing causes. If God foreknows that our actions will come to pass in the way we call freely, (and we have as much right to this supposition as our opponents have to the contrary,) then, as foreknowledge infers necessity, our actions are necessarily free. And surely, if the necessity which is inferred from foreknowledge, is predicable of freedom itself, it cannot be inconsistent with it.

In other words, if the necessity of human volitions, according to the scheme of Edwards, be a fact, then it was foreknown to God that such is the fact; and, if we please, we may infer the fact from his foreknowledge, after having inferred his foreknowledge from the fact. On the other hand, if the scheme of necessity be a mere hypothesis, having no corresponding reality in the universe; then God never foreknew that it is according to such scheme that all human actions are brought to pass; unless he foreknew things to be necessitated which in reality are not necessitated. Hence, we can prove nothing by reasoning from the foreknowledge of God; except what we first assume to be true, and consequently foreknown to Him; and, if we choose to resort to this pitiful way of begging the question, we may prove our hypothesis just as well as any other.

The foreknowledge of an event, as I have already said, proves nothing more nor less than _the bare certainty_ of its future existence; it decides nothing as _to the manner_ of its coming into existence. The necessitarian may ring the changes upon this subject as long as he pleases, and all he can possibly make out of it is, that if God foreknows a thing, it will certainly be, and to suppose otherwise, is a contradiction. Thus, says Edwards, "To suppose the future volitions of moral agents not to be necessary events; or, which is the same thing, events which it is not possible but that they may come to pass; and yet to suppose that God certainly foreknows them, and knows all things, is to suppose God's knowledge to be inconsistent with itself. For to say that God certainly, and without all conjecture, knows that a thing will infallibly be, which at the same time he knows to be so _contingent_ that it may possibly not be, is to suppose his knowledge inconsistent with itself; or that one thing he knows is utterly inconsistent with another thing he knows. It is the same as to say, he now knows a proposition to be of certain infallible truth, which he knows to be of contingent uncertain truth. If a future volition is so without all necessity, that nothing hinders but it may not be, then the proposition which asserts its future existence is so uncertain, that nothing hinders but that the truth of it may entirely fail. And if God knows all things, he knows this proposition to be thus uncertain; and that is inconsistent with his knowing it to be infallibly true; and so inconsistent with his knowing that it is true." p. 117. Now all this going around and around amounts to just this, that if God certainly and infallibly foreknows a thing, he certainly and infallibly foreknows it, or that if it will certainly come to pass, it will certainly come to pass.

We admit that the certainty of all future events is implied in God's foreknowledge of them. Does the argument in question prove any more than the bare fact of the certainty of the events foreknown? The argument, so far as we have yet followed it, clearly does not. It merely proves the bare fact of the certainty of existence. Indeed, Edwards himself says, that "metaphysical or philosophical necessity," (and this is the necessity for which he here contends,) "is nothing different from their certainty." p. 23. And the younger Edwards frequently says, "If a proposition asserting some future event, be a real and absolute truth, there is an absolute certainty of the event; _such absolute certainty is all that is implied in the divine foreknowledge; and all the moral necessity for which we plead_." p. 160. Now, if these writers merely mean that a thing is certain, when they say it is necessary, it is to be regretted that they did not use the right word. It would have saved their works from no little confusion.

But the truth is, that the moral necessity for which they contend consists sometimes in the certainty of an event, and sometimes in _the ground_ of that certainty. Volitions are said to be morally necessitory in their definition, and in their system, because they are _made certain by the influence of moral causes_. But in their arguments, and the defence of their system, _the bare absolute certainty_, without any reference to the ground of it, is frequently all that is meant by moral necessity. Thus, they build upon one idea of necessity, while they attack and defend themselves upon another idea thereof.

This is our present starting point then, agreed upon by all sides, that the foreknowledge of God infers the certainty of all future realities. Now, how can we conclude from hence, that the volitions of moral agents are, not only certain, but rendered certain by the influence of moral causes? It may be said, that it is sufficient that the foreknowledge of God proves that human volitions will certainly come to pass in some way or other; for if they will certainly come to pass in any way, we know that they must have some cause of their existence; and it is just as absurd to suppose that a volition can come into being without any cause of its existence, as it is to suppose that a world can come into being of itself. If this ground should be taken, (and it certainly will be,) the reply is obvious. It would show that the divine prescience can only prove the certainty of future events while it is left to the old maxim, that every effect must have a cause, in order to make out the doctrine of moral necessity, or the point in dispute! It would show, that after all the parade made with the divine prescience, it leaves the whole argument to rest upon ground which has already been occupied by one side, and fully considered by the other! It would only show, that a great pretence of demonstration had been made from the foreknowledge of God; whereas, in fact, it proves nothing to the purpose, unless "its most impotent and lame conclusion" be helped out by something else!

Another attempt is made to link the conclusion drawn from the foreknowledge of God, with the point to be established by the necessitarian. It is said, that God could not foreknow all future events, unless he views them as connected with known causes. This ground is taken by many eminent necessitarians. Thus, says Dr. John Dick, "Future events cannot be foreseen, unless they are certain; they cannot be certain, unless God have determined to bring them to pass."

The same position is assumed by President Edwards, "There must be a certainty in things themselves," says he, "before they are certainly foreknown." . . . "There must be a certainty in things to be a ground of certainty of knowledge, and render things capable of being known to be certain." p. 122. Now, what is this certainty in things themselves, or in human volitions, without which they are incapable of being foreknown? The answer is obvious; for Edwards every where contends, that unless volitions are brought to pass by the _influence_ of moral causes--that unless they are necessarily produced by an "effectual power and efficacy"--they are altogether uncertain and contingent, and connected with nothing that can render them certain. Hence, he clearly maintains, that unless human volitions are necessarily brought to pass by the influence of motives, they are not certain in themselves, and hence are incapable of being foreknown. And besides, he has a laboured argument to prove, that God could not foreknow the future volitions of moral agents, unless he views them as "necessarily connected with something else that is evident." pp. 115-117. This something else is not foreknowledge itself; for it is the ground of foreknowledge, it is the necessary influence of motives, or moral causes. But we need not dwell upon this point, as this is so evidently his meaning; and if it is not, then it is nothing to the purpose.
