Let us compare the two theories particularly, although at the hazard of some repetition.
Contingent self-determination represents the will as a cause making its nisus or volitions of itself, and determining their direction of itself—now obeying reason, and now obeying passion. If it be asked why it determines in a particular direction?—if this particular direction in which it determines be that of the reason?—then it may be said, that it determines in this direction because it is reasonable;—if this particular direction be that of passion, as opposed to reason, then it may be said that it determines in this direction, because it is pleasing. But if it be asked why the will goes in the direction of reason, rather than in that of passion, as opposed to reason?—we cannot say that it is most reasonable to obey reason and not passion; because the one is all reason, and the other is all passion, and of course they cannot be compared under the reasonable; and no more can they be compared under the pleasing,—when, by the pleasing, we understand, the gratification of desire, as opposed to reason. To obey reason because it is reasonable, is nothing more than the statement of the fact that the will does obey reason. To obey desire because it is desirable, is nothing more than the statement of the fact that the will does obey desire. The will goes in one direction rather than in another by an act of self-determination, which neither admits of, nor indeed requires any other explanation than this, that the will has power to do one or the other, and in the exercise of this power, it does one rather than the other.
To this stands contrasted the system of Edwards; and what is this system? That the will is determined by the strongest motive;—and what is the strongest motive? The greatest apparent good, or the most agreeable:—what constitutes the greatest apparent good, or the most agreeable? The correlation of will or sensitivity and the object. But why does the correlation make one object appear more agreeable than another; or make the same object at one time appear agreeable, at another time disagreeable? Now this question is equivalent to the question,—why does the will go in the direction of one object rather than of another; or go in the direction of a given object at one time, and in opposition to it at another time? For the will to determine itself toward an object in one system, answers to the will having the sense of the most agreeable towards an object in Edwards’s system. If Edwards should attempt to give an answer without going beyond the motive, he could only say that the sensitivity has the power of being affected with the sense of the most agreeable or of the most disagreeable; and that in the exercise of this power it is affected with the one rather than with the other. He could not say that to obey reason appears more agreeable than to obey passion as opposed to reason, for the obedience of the will on his system, is nothing more than a sense of the most agreeable. Nor could he say it is more reasonable to obey reason, for reason cannot be compared with its opposite, under the idea of itself; and if he could say this, it amounts to no more than this, on his system, that it is most agreeable to obey the reasonable;—that is, the reasonable is obeyed only as the most agreeable: but obedience of will being nothing more than the sense of the most agreeable, to say it is obeyed because most agreeable, is merely to say that it awakens the sense of the most agreeable; that is, it is obeyed, because it is obeyed.
To refer the motive to the divine determination makes volition necessary to the man, and throws the difficulty in question, if it is to be considered a difficulty, only farther back.
If God’s will determines in the direction of the reasonable because it is most agreeable, then we ask, why is it the most agreeable? If the reply be, because it is most reasonable, then we are only moving in a circle; but if the agreeable be taken as an ultimate fact, then inasmuch as to will is only to have the sense of the most agreeable, it follows that God has the sense of the most agreeable towards an object only because it is most agreeable to him, or awakens this sense in him; and thus the question why God wills in one direction rather than in another, or what is the cause of his determination, is not answered by Edwards, unless he says with us that the will in itself as a power to do or not to do, or to do one thing, or its opposite, is a sufficient explanation, and the only possible explanation;—or unless he refers the divine will to an antecedent cause, and this again to another antecedent cause, in an endless series—and thus introduce the two-fold error of an endless series, and an absolute necessity.
All possible volitions, according to the scheme of psychology I have above given, must be either in the direction of the reason or of the sensitivity, or in the indifferency of both. If the volition be in the direction of the reason, it takes the characteristics of rational, good, &c. If in the direction of the sensitivity, it takes its characteristic from the nature of the particular desire which it obeys:—it is generous, benevolent, kind, &c.—or it is malicious, envious, unkind, vicious, &c. What moves the will to go in the direction of the reason? Nothing moves it; it is a cause per se; it goes in that direction because it has power to go in that direction. What moves the will to go in the direction of the sensitivity? Nothing moves it; it is a cause per se; it goes in that direction because it has power to go in that direction.
There are in the intelligence or reason, as united with the will in the constitution of the mind, necessary convictions of the true, the just, the right. There are in the sensitivity, as united in the same constitution, necessary affections of the agreeable and the disagreeable in reference to various objects. The will as the power which by its nisus produces changes or phenomena, is conscious of ability to go in either of these directions, or in opposition to both. Now when it makes its nisus or volition in reference to the true, the just, the good; should we attempt to explain this nisus by saying that the true, the just, the good, affect the sensitivity agreeably, this would only amount to saying that the nisus is made towards the true, not as the true, but only as the agreeable; and then we would introduce the law that the nisus is always made in the direction of the agreeable. But then again we might seek to explain why the nisus is always made in the direction of the agreeable. Is it of an antecedent necessity? Then we have an absolute and universal necessity. Is it because to go in the direction of the agreeable seems most rational? Then it follows that the nisus is made towards the agreeable not as the agreeable, but only as the rational; and then we would introduce the law that the nisus is always made in the direction of the rational. But then again we might seek to explain why this nisus is always made in the direction of the rational. Is it of an antecedent necessity? Then here likewise we have an absolute and universal necessity. Is it because to go in the direction of the rational seems most agreeable? Then we are winding back in a circle to our first position.
How shall we escape from these difficulties? Shall we adopt the psychology of Edwards, and make the will and the sensitivity one? Then as the volition is always the strongest affection of the agreeable, if the sensitivity be necessary, volitions are necessary, and we are plunged headlong again into an absolute and universal necessity. If the sensitivity be not necessary, then we have shown fully, above, that we have to account for its various determinations just as we are supposed to be called upon to account for the various determinations of the will when considered as a power distinct from the sensitivity:—we are met with the questions, why does the sensitivity represent this object as more agreeable than that object?—or the same object as agreeable at one time, and disagreeable at another? Or if these various determinations are resolved into an antecedent necessity comprehending them, then we go up to the antecedent cause in which this necessity resides, and question it in like manner.
But one thing remains, and that is to consider the will as primary cause, contingent in opposition to being necessitated—a cause having in itself the power of making these various volitions or nisus, and neither asking nor allowing of any explanation of its acts, or their particular direction, save its own peculiarity and energy as will.
The question respecting the indifferency of will must now be considered. The term indifferency comes up in consequence of considering the will as distinct from the sensitivity. It is not desire or feeling—it is a power indifferent to the agreeableness or disagreeableness of objects.
