The element of mystery here lies in the secondary or subjective aspect, but it is placed strictly without the line of deduction and is a merely unexplained accompaniment of a series of changes otherwise fully accounted for.
A second theory—as strictly causational as the former—recognises the presence of a subjective factor. In some of the quotations from Mr. Spencer's "Psychology," given above, it will have been seen that, at the point of development of nerve junctions when different currents meet in the developed ganglion and in proportion as the system becomes more complex, Mr. Spencer asserts not only the rise of a secondary aspect, but of an additional factor. The element of mystery here is the entrance of this additional factor, capable of taking part as an active agent in the affairs of the organism. But since it is itself the result of experience and the organization of experiences of the physical nervous system, it is strictly of a causational or deductive order, and after its unexplained inception, it has to be studied strictly in the scientific order of development and action. Notwithstanding that it plays a part in the conduct of life, and notwithstanding that its dependence upon physical organization and development is so intimate, and that this development again cannot be understood without it—notwithstanding all this incomprehensibleness of relation and our ignorance of its origin, the Evolutionist maintains the orderly development of organism and actions, including the subjective as resultants of the relations of original factors, although he may be for the time being ignorant of the nature of the processes.
It will therefore be seen that in either case he holds the deterministic theory of volition, and believes all purposed actions to be actions determined by pre-existing causes, whether he regards these causes as the structure and condition of nerve centres, or as feelings and thoughts, or whether he regards them as ascribable to some law of correlation between the two.
Nevertheless, it seems to be incumbent upon all writers dealing with the subject of Ethics to define their position as to the Free Will controversy. It is needless to say that we accept unreservedly the deterministic theory, though it may be necessary to attempt its reconciliation with the consciousness in persons of Free Will.
We here make a distinction between theories of Will and theories of Free Will. What we have just been considering have been theories of will or volition. They are of the deterministic order because in either case the actions are wholly determined by preceding facts. Human and all actions of organisms are held to be merely resultants of pre-existing factors and their relations. This is the theory held by all scientific philosophers, and the one most analogous to what we know of physical science as well as most in conformity with actual experience of human conduct. Another theory—arising no doubt in the mystery of the secondary aspect or in the mystery of the origin of the subjective factor, denies the rigidity of the scientific order, and asserts the presence and activity of a self-determining factor, thus placing volitional action beyond the scientific order of the dependent and related successions of cause and effect.
Perhaps, however, we would be more correct in attributing the confidence with which this theory of a self-determining power is sometimes held to another cause. There is in all human beings the consciousness of a power more or less developed to regulate their own actions; and this process of self-regulation is held to be inconsistent with the deterministic theory. There can be no doubt that there is such a consciousness and we think there can be no doubt also that there is such a power. The superficial evolutionist, indeed, may admit the consciousness, which he may explain as a secondary aspect of conflicting nerve-currents, and laugh in his sleeve at the egotistic vanity of a trustful man proud of his power of Will. But we think a deeper explanation, and one more commensurate with the phenomena, is to be found: and this brings us back to the distinction, as indicated at the outset of this section, between theories of Will or Volition, and theories of Free Will or the power of regulating one's own conduct.
Will, in its scientific sense, is merely volition, i.e. the mental state accompanying or immediately preceding action. The nature of the action, good, bad, or indifferent, is immaterial. Technically speaking, all volitions are equal, viewed as such. The volition for the time being is the Will for the time being. The Will of a man is the totality of his volitions during the whole of his lifetime. It is a general or collective term relating to conscious actions, or states of consciousness immediately preceding actions, and is not the name of an entity.
But if Will is the volition for the time being, irrespective of any qualitative characteristic, then we have to inquire as to the applicability to it of the term "Free." Now this term is antithetical to the two terms "restrained" and "constrained." Thus if a man's actions are hindered or forcefully prevented by the Will of others, that man's actions are not free. But if some of a man's motives are restrained or his actions constrained by the predominance of some other of his motives—as, for instance, when he performs actions which his conscience tells him are wrong—in his Will not free? The actions are his volitions. If some motives are restrained, and therefore not to be considered free, still the others which have gained the predominance have thereby become his Will; their operation proves their non-restraint or freedom, and the volition or Will is still free. The action is an evidence of freedom. Volition is always free. It is of different kinds, but this does not affect the conclusion that volition proves its own freedom. The Will is always and under all circumstances free.
