Cudworth, in his great work entitled “The true Intellectual System of the Universe,” shows clearly the connexion between fatalism and atheism. This work seems to have grown out of another undertaking, which contemplated specifically the question of liberty and necessity, and its bearing upon morality and religion. The passage in the preface, in which he informs us of his original plan, is a very full expression of his opinion. “First, therefore, I acknowledge,” says he, “that when I engaged the press, I intended only a discourse concerning liberty and necessity, or, to speak out more plainly, against the fatal necessity of all actions and events; which, upon whatsoever grounds or principles maintained, will, as we conceive, serve the design of atheism, and undermine Christianity, and all religion, as taking away all guilt and blame, punishments and rewards, and plainly rendering a day of judgement ridiculous.” This opinion of the tendency of the doctrine of a necessitated will, is the germ of his work. The connexion established in his mind between this doctrine and atheism, naturally led him to his masterly and elaborate exposition and refutation of the latter.
The arguments of many atheists might be referred to, to illustrate the connexion between necessity and atheism. I shall here refer, however, to only one individual, remarkable both for his poetic genius and metaphysical acumen. I mean the late Piercy Bysshe Shelley. He openly and unblushingly professed atheism. In his Queen Mab we find this line: “There is no God.” In a note upon this line, he remarks: “This negation must be understood solely to affect a creative Deity. The hypothesis of a pervading spirit, co-eternal with the universe, remains unshaken.” This last hypothesis is Pantheism. Pantheism is really the negation of a creative Deity,—the identity or at least necessary and eternal co-existence of God and the universe. Shelley has expressed this clearly in another passage:
“Spirit of nature! all-sufficing power,
Necessity! thou mother of the world!”
In a note upon this passage, Shelley has argued the doctrine of the necessary determination of will by motive, with an acuteness and power scarcely inferior to Collins or Edwards. He makes, indeed, a different application of the doctrine, but a perfectly legitimate one. Collins and Edwards, and the whole race of necessitarian theologians, evidently toil under insurmountable difficulties, while attempting to base religion upon this doctrine, and effect their escape only under a fog of subtleties. But Shelley, in daring to be perfectly consistent, is perfectly clear. He fearlessly proceeds from necessity to pantheism, and thence to atheism and the destruction of all moral distinctions. “We are taught,” he remarks, “by the doctrine of necessity, that there is neither good nor evil in the universe, otherwise than as the events to which we apply these epithets have relation to our own peculiar mode of being. Still less than with the hypothesis of a God, will the doctrine of necessity accord with the belief of a future state of punishment.”
I here close my deductions from this system. If these deductions be legitimate, as I myself cannot doubt they are, then, to the largest class of readers, the doctrine of necessity is overthrown: it is overthrown by its consequences, and my argument has the force of a reductio ad absurdum. If a self-determined will appear an absurdity, still it cannot be as absurd as the contrary doctrine, if this doctrine involve the consequences above given. At least, practical wisdom will claim that doctrine which leaves to the world a God, and to man a moral and responsible nature.
A question will here very naturally arise: How can we account for the fact that so many wise and good men have contended for a necessitated will, as if they were contending for the great basis of all morality and religion? For example, take Edwards himself as a man of great thought and of most fervent piety. In the whole of his treatise, he argues with the air and manner of one who is opposing great errors as really connected with a self-determined will. What can be stronger than the following language: “I think that the notion of liberty, consisting in a contingent self-determination of the will, as necessary to the morality of men’s dispositions and actions, is almost inconceivably pernicious; and that the contrary truth is one of the most important truths of moral philosophy that ever was discussed, and most necessary to be known.” The question is a fair one, and I will endeavour to answer it.
1. The impossibility of a self-determining will as being in itself a contradictory idea, and as leading to the consequence of affirming the existence of effects without causes, takes strong hold of the mind in these individuals. This I believe, and hope to prove in the course of this treatise, to be a philosophical error;—but it is no new thing for great and good men to fall into philosophical errors.
As, therefore, the liberty consisting in a self-determining will, or the liberty of indifference, as it has been technically called, is conceived to be exploded, they endeavour to supply a liberty of spontaneity, or a liberty lying in the unimpeded connexion between volition and sequents.
Hobbes has defined and illustrated this liberty in a clearer manner than any of its advocates: “I conceive,” says he, “liberty to be rightly defined,—the absence of all impediments to action, that are not contained in the nature and intrinsical quality of the agent. As for example, the water is said to descend freely, or is said to have liberty to descend by the channel of the river, because there is no impediment that way; but not across, because the banks are impediments: and though water cannot ascend, yet men never say, it wants the liberty to ascend, but the faculty or power, because the impediment is in the nature of the water, and intrinsical. So also we say, he that is tied, wants the liberty to go, because the impediment is not in him, but in his hands; whereas, we say not so of him who is sick or lame, because the impediment is in himself,”—that is, he wants the faculty or power of going:—this constitutes natural inability. Liberty is volition acting upon physical instrumentalities, or upon mental faculties, according to a fixed and constituted law of antecedents, and meeting with no impediment or overcoming antagonistic power. Natural ability is the fixed and constituted antecedence itself. Hence there may be natural ability without liberty; but liberty cannot be affirmed without natural ability. Both are necessary to constitute responsibility. Natural ability is volition known as a stated antecedent of certain effects. Liberty is this antecedent existing without impediment or frustration. Since this is the only possible liberty remaining, and as they have no wish to be considered fatalists, they enlarge much upon this; not only as the whole of liberty actually existing, but as the full and satisfactory notion of liberty.
