In the first place, this is no higher liberty than what brutes possess. They have power, opportunity, or advantage, to do as they please. Effects follow their volitions by as certain a law as effects follow the volitions of men.
In the second place, this is no higher liberty than slaves possess. Slaves uniformly do as they please. If the motive be the lash, or the fear of the lash, still, in their case as well as in that of brutes under similar circumstances, the volition which takes place is the most pleasing at the moment. The slave and the animal do what is most pleasing to them, or do according to their pleasure, When the one drags the plough and the other holds it. Nay, it is impossible for any animal, rational or irrational, to act without doing what is most pleasing to him or it. Volition is always as the greatest apparent good, or as the sense of the most pleasant or agreeable.
If any should reply that slaves and animals are liable to be fettered, and this distinguishes them from the free, I rejoin that every being is liable to various restraints; none of us can do many things which in themselves appear desirable, and would be objects of volition if there were known to be an established connexion between them and our wills. We are limited in our actions by the powers of nature around us; we cannot overturn mountains, or command the winds. We are limited in the nature of our physical being. We are limited by our want of wealth, knowledge, and influence. In all these respects, we may, with as much propriety as the slave, be regarded as deprived of liberty. It does not avail to say that, as we never really will what we know to be impossible or impracticable, so in relation to such objects, neither liberty or a want of liberty is to be affirmed; for the same will apply to the fettered slave; he does not will to walk or run when he knows it to be impossible. But in relation to him as well as to every other being, according to this system it holds true, that whether he act or forbear to act, his volitions are as the most agreeable.
All creatures, therefore, acting by volition, are to be accounted free, and one really as free as another.
In the third place, the liberty here affirmed belongs equally to every instance of stated antecedence and sequence.
The liberty which is taken to reside in the connexion between volition and effects, is a liberty lying in a connexion of stated antecedence and sequence, and is perfect according as this connexion is necessary and unimpeded. The highest form of liberty, therefore, is to be found in the most absolute form of necessity. Liberty thus becomes identified also with power: where there is power, there is liberty; and where power is the greatest, that is, where it overcomes the most obstacles and moves on irresistibly to its effects, there is the greatest degree of liberty. God is the most free of all beings, because nothing can impede his will. His volitions are always the antecedents of effects.
But obviously we do not alter the relation, when we change the terms. If liberty lie in the stated antecedence of volition to effects, and if liberty is measured by the necessity of the relation, then when the antecedent is changed, the relation remaining the same, liberty must still be present. For example: when a volition to move the arm is followed by a motion of the arm, there is liberty; now let galvanism be substituted for the volition, and the effect as certainly takes place; and as freedom is doing as we please, or will, “without considering how this pleasure (or will) comes to be as it is;” that is, without taking its motive into the account. So likewise, freedom may be affirmed to be doing according to the galvanic impulse, “without considering how” that impulse “comes to be as it is.”
If we take any other instance of stated antecedence and sequence, the reasoning is the same. For example, a water wheel in relation to the mill-stone: when the wheel turns, the mill-stone moves. In this case freedom may be defined: the mill-stone moving according to the turn of the wheel, “without considering how” that turn of the wheel “comes to be as it is.” In the case of human freedom, freedom is defined, doing according to our volitions, without considering how the volition comes to be as it is; doing “according to choice, without taking into the meaning of the word anything of the cause of that choice.” (p. 39.)
If it be said that in the case of volition, we have the man of whom to affirm freedom; but in the case of the wheel and mill-stone, we have nothing of which liberty can properly be affirmed. I reply, that liberty must be affirmed, and is properly affirmed, of that to which it really belongs; and hence as volition is supposed to belong to the spiritual essence, man; and this spiritual essence is pronounced free, because volition appears in it, and is attended by consequences:—so, likewise, the material essence of the wheel may be pronounced free, because motion belongs to it, and is followed by consequences. As every being that has volition is free, so likewise every thing that hath motion is free:—in every instance of cause and effect, we meet with liberty.
But volition cannot be the characteristic of liberty, if volition itself be governed by necessity: and yet this system which affirms liberty, wherever there is unimpeded volition, makes volition a necessary determination. In the fact of unimpeded volition, it gives liberty to all creatures that have volition; and then again, in the fact of the necessary determination of volition it destroys the possibility of liberty. But even where it affirms liberty to exist, there is no new feature to characterize it as liberty. The connexion between volition and its stated consequences, is a connexion as necessary and absolute as the connexion between the motive and the volition, and between any antecedent and sequent whatever. That my arm should move when I make a volition to this effect, is just as necessary and just as incomprehensible too, as that water should freeze at a given temperature: when the volition is impeded, we have only another instance of necessity,—a lesser force overcome by a greater.
