VI.The Impulses and the Will.
Locke, after discussing the subject of innate ideas in their relation to knowledge, goes on to discuss their practical side, or connection with will. We shall follow him in this as Leibniz does; but we shall consider in connection with this, Leibniz’s general theory of will, which is developed partially in this chapter, but more completely in his critical remarks upon what Locke has to say of the notion of “power.” Since the theory of morals is as closely connected with will as the theory of knowledge is with the intellect, we shall supplement this discussion with what Leibniz says upon the ethical question, drawing our material somewhat freely from his other writings.
The doctrine of will which Leibniz propounds is in closest harmony with his conception of intelligence, and this not merely in the way of empirical juxtaposition, but as the result of his fundamental principles. If we recall what has been said concerning the monad, we shall remember that it is an activity, but an activity with a content. It is a force, but a force which mirrors the universe. The content, that portion of reality which is reflected in the action, is knowledge, or the idea; the activity which brings this about is will, or the volition. They are related to each other as form and content. There is, strictly speaking, no “state” of mind; there is only a tension, a pushing forward of mind. There is no idea which is not a volition. Will is thus used, in a very broad sense, as equivalent to action. Since, however, the activity of the monad is in no case aimless, but has an end in view, the will is not mere activity in general, it is action towards some definite end. And since the end at which the monad aims is always the development of an idea, the reflection of some constituent of the universe, the will is always directed towards and determined by some idea of the intellect.
We have seen, however, that there are various stages in the reflecting power of the soul, or in the realization of intellect. Taking only the broadest division, there are perception and apperception; that is, there are the conscious and the unconscious mirroring of reality. We shall expect, then, to find two corresponding stages of volition. Leibniz calls these stages “appetition” and “volition” in the narrower sense. The constant tendency in every monad to go from one perception to another,—that is, the following of the law of development,—constitutes appetition. If joined to feeling, it constitutes instinct. Since, again, there are two degrees of apperception, one of empirical, the other of rational, consciousness, we shall expect to find two grades of volition proper,—one corresponding to action for conscious particular ends; the other for ends which are proposed by reason, and are hence universal. In this chapter we shall simply expand and illustrate these various propositions.
Sensations, looked at not as to what they represent, but in themselves, are impulses. As such they constitute the lowest stage of will. Impulsive action then includes all such as occurs for an end which is unknown, or at best but dimly felt. Such action may be called blind, not in the sense that it is without reason, but in the sense that reason is not consciously present. We are not to think of this instinctive action, however, as if it were found simply in the animals. Much of human action is also impulsive; probably, indeed, an impulsive factor is contained in our most rational willing. We are never able to take complete account of the agencies which are acting upon us. Along with the reasons of which we are conscious in choosing, there are mingled faint memories of past experience, subconscious solicitations of the present, dim expectations for the future. Such elements are decisive factors far more than we realize.
Indeed, it is because of the extent to which such unconscious influences bear upon us and move us that there arises the idea of indifferent or unmotivated choice. Were both motive and choice unconscious, the question as to whether choice were antecedently determined would not arise; and were our motives and their results wholly in consciousness, the solution of the question would be evident. But when we are conscious of our choice, but are not conscious of our impulses and motives, we get the impression that our choice is unmotived, and hence come to believe in “indifferent freedom,”—the ability to choose as we will.
We shall shortly take up in more detail the theory of Leibniz regarding the freedom of will; and it is needful here to remark only that the conception which makes it consist in ability to choose without reason is in direct contradiction to his fundamental thought,—namely, that there can be no activity which does not aim at some reflection of the universe, by which, therefore, it is determined. From the psychological point of view, it is interesting also to notice how Leibniz’s theory of unconscious ideas enables him to dispose of the strongest argument for indifferent choice,—that drawn from the immediate “testimony” of consciousness.
Upon the origin and nature of desires Leibniz has much more to say than about the impulses. His account of the transition from impulse to desire is based upon the conception of unconscious ideas. Slight and imperceptible impulses are working upon us all the time. Indeed, they are a necessity; for the actual state of a soul or monad at any time is, of course, one of incompleteness. Our nature must always work to free itself from its hindrances and obtain its goal of complete development. But it will not do this unless there is some stimulus, some solicitation to induce it to overcome its limitation. There is found accordingly in our every condition a feeling of dissatisfaction, or, using Locke’s word, of “uneasiness;” and it is this which calls forth that activity which brings about a nearer approach to the soul’s real good. But Leibniz differs from Locke in saying that this feeling of uneasiness is not a distinct, or even in most cases a conscious, one. It is not pain, although it differs from pain only in degree. Uneasiness and pain are related to each other as appetite for food is to hunger,—the first suffices to stimulate us to satisfaction, but if the want is not met, results in actual pain; if met, these “half pains” become tributary to pleasure itself. These unconscious stimuli to action result in actions which meet the want, and the aggregation of these satisfactions results in pleasure. In Leibniz’s own words:—
“If these elements of pain were themselves true pains, we should always be in a state of misery, even in pursuing the good. But since there is always going on a summation of minute successes in overcoming these states of uneasiness, and these put us more and more at ease, there comes about a decided pleasure, which often has greater value even than the enjoyment of the good. Far, then, from regarding this uneasiness as a thing incompatible with happiness, I find that it is an essential condition of our happiness. For this does not consist in perfect possession, which would make us insensible and stupid, but in a constant progress towards greater results, which must always be accompanied, accordingly, by this element of desire or uneasiness.”
And again he says that “we enjoy all the advantages of pain without any of its inconveniences. If the uneasiness should become too distinct, we should be miserable in our awaiting the good which relieves it; but as it is, there is a constant victory over these half-pains, which we always find in desire, and this gives us a quantity of half-pleasures, whose continuance and summation (for they acquire force like a moving body as it falls) result in a whole and true pleasure.” In short, there is indeed an element of pain in all desire which stimulates us to action, and therefore to higher development. But ordinarily this element of pain is not present as such in consciousness, but is absorbed in the pleasure which accompanies the realization of the higher good. Thus Leibniz, accepting and emphasizing the very same fact that served Schopenhauer as a psychological base of pessimism, uses it as a foundation-stone of optimism.
But desire, or the conscious tendency towards something required as a good, accompanied by the dim feeling of uneasiness at its absence, does not yet constitute the complete act of volition. “Several impulses and inclinations meet in forming the complete volition which is the result of their conflict.” In the concrete act of will there are contained impulses which push us towards some end whose nature is not known; there is desire both in its inchoate stage, where pleasure and pain are not in consciousness, and in its formed state, where the pain and pleasure are definitely
