This relation of contraries to the higher conception which logically must include them is one of the well-worn problems of the higher metaphysics.
The proper explanation would seem to be, as suggested above, that the synthesis of contraries is capable of formal expression only, but not of interpretation. In pursuing the search for their union we pass into a realm of thought not unlike that of the mathematician when he deals with hypothetical quantities, those which can only be expressed in symbols—, √1 for example—but uses them to good purpose in reaching real results. The law does not fail, but its operations can no longer be expressed under material images. They are symbolic and for speculative thought alone, though pregnant with practical applications.
As I have hinted, in all real contraries it is theoretically possible to accept either the one or the other. As in mathematics, all motion can be expressed either under formulas of initial motion (mechanics), or of continuous motion (kinematics), or as all force can be expressed as either static or as dynamic force; in either case the other form assuming a merely hypothetical or negative position; so the logic of quality is competent to represent all existence as ideal or as material, all truth as absolute or all as relative, or even to express the universe in formulæ of being or of not-being. This perhaps was what Heraclitus meant when he propounded his dark saying: “All things are and are not.” He added that “All is not,” is truer than “All is.” Previous to his day, Buddha Sakyamuni had said: “He who has risen to the perception of the not-Being, to the Unconditioned, the Universal, his path is difficult to understand, like the flight of birds in the air.”37–1 Perhaps even he learned his lore from some older song of the Veda, one of which ends, “Thus have the sages, meditating in their souls, explained away the fetters of being by the not-being.”37–2 The not-being, as alone free from space and time, impressed these sages as the more real of the two, the only absolute.
The error of assigning to the one universal a preponderance over the other arose from the easy confusion of pure with applied thought. The synthesis of contraries exists in the formal law alone, and this is difficult to keep before the mind. In concrete displays they are forever incommensurate. One seems to exclude the other. To see them correctly we must there treat them as alternates. We may be competent, for instance, to explain all phenomena of mind by organic processes; and equally competent to explain all organism as effects of mind; but we must never suppose an immediate identity of the two; this is only to be found in the formal law common to both; still less should we deny the reality of either. Each exhausts the universe; but at every step each presupposes the other; their synthesis is life, a concept hopelessly puzzling unless regarded in all its possible displays as made up of both.
This indicates also the limits of explanation. By no means every man’s reason knows when it has had enough. The less it is developed, the further is it from such knowledge. This is plainly seen in children, who often do not rest satisfied with a really satisfactory explanation. It is of first importance to be able to recognize what is a good reason.
I may first say what it is not. It is not a cause. This is nothing more than a prior arrangement of the effect; the reason for an occurrence is never assigned by showing its cause. Nor is it a caprice, that is, motiveless volition, or will as a motor. In this sense, the “will of God” is no good reason for an occurrence. Nor is it fate, or physical necessity. This is denying there is any explanation to give.
The reason can only be satisfied with an aliment consubstantial with itself. Nothing material like cause, nor anything incomprehensible like caprice, meets its demands. Reason is allied to order, system and purpose above all things. That which most completely answers to these will alone satisfy its requirements. They are for an ideal of order. Their complete satisfaction is obtained in universal types and measures, pure abstractions, which are not and cannot be real. The formal law is the limit of explanation of phenomena, beyond which a sound intellect will ask nothing. It fulfils all the requirements of reason, and leaves nothing to be desired.
Those philosophers, such as Herbert Spencer, who teach that there is some incogitable “nature” of something which is the immanent “cause” of phenomena, delude themselves with words. The history and the laws of a phenomenon are its nature, and there is no chimerical something beyond them. They are exhaustive. They fully answer the question why, as well as the question how.39–1
For it is important to note that the word “law” is not here used in the sense which Blackstone gives to it, a “rule of conduct;” nor yet in that which science assigns to it, a “physical necessity.” Law in its highest sense is the type or form, perceived by reason as that toward which phenomena tend, but which they always fail to reach. It was shown by Kant that all physical laws depend for their validity on logical laws. These are not authoritative, like the former, but purposive only. But their purpose is clear, to wit, the attainment of proportion, consistency or truth. As this purpose is reached only in the abstract form, this alone gives us the absolutely true in which reason can rest.
In the concrete, matter shows the law in its efforts toward form, mind in its struggle for the true. The former is guided by physical force, and the extinction of the aberrant. The latter, in its highest exhibition in a conscious intelligence, can alone guide itself by the representation of law, by the sense of Duty. Such an intelligence has both the faculty to see and the power to choose and appropriate to its own behoof, and thus to build itself up out of those truths which are “from everlasting unto everlasting.”
A purely formal truth of this kind as something wholly apart from phenomena, not in any way connected with the knowledge derived through the senses, does not admit of doubt and can never be changed by future conquests of the reasoning powers. We may rest upon it as something more permanent than matter, greater than Nature.
Such was the vision that inspired the noble lines of Wordsworth:—
“What are things eternal?—Powers depart,
Possessions vanish, and opinions change,
And passions hold a fluctuating seat;
But, by the storms of circumstance unshaken,
And subject neither to eclipse nor wane,
Duty exists; immutably survive
For our support, the measures and the forms
Which an abstract intelligence supplies;
Whose kingdom is where time and space are not.”
There is no danger that we shall not know what is thus true when we see it. The sane reason cannot reject it. “The true,” says Novalis, “is that which we cannot help believing.” It is the perceptio per solam essentiam
