The Illative Sense
Truths such as these, which are too obvious to be called irresistible, are illustrated by what we see in universal nature. Every being is in a true sense sufficient for itself, so as to be able to fulfil its particular needs. It is a general law that, whatever is found as a function or an attribute of any class of beings, or is natural to it, is in its substance suitable to it, and subserves its existence, and cannot be rightly regarded as a fault or enormity. No being could endure, of which the constituent parts were at war with each other. And more than this; there is that principle of vitality in every being, which is of a sanative and restorative character, and which brings all its parts and functions together into one whole, and is ever repelling and correcting the mischiefs which befall it, whether from within or without, while showing no tendency to cast off its belongings as if foreign to its nature. The brute animals are found severally with limbs and organs, habits, instincts, appetites, surroundings, which play together for the safety and welfare of the whole; and, after all exceptions, may be said each of them to have, after its own kind, a perfection of nature. Man is the highest of the animals, and more indeed than an animal, as having a mind; that is, he has a complex nature different from theirs, with a higher aim and a specific perfection; but still the fact that other beings find their good in the use of their particular nature, is a reason for anticipating that to use duly our own is our interest as well is our necessity.
What is the peculiarity of our nature, in contrast with the inferior animals around us? It is that, though man cannot change what he is born with, he is a being of progress with relation to his perfection and characteristic good. Other beings are complete from their first existence, in that line of excellence which is allotted to them; but man begins with nothing realized (to use the word), and he has to make capital for himself by the exercise of those faculties which are his natural inheritance. Thus he gradually advances to the fulness of his original destiny. Nor is this progress mechanical, nor is it of necessity; it is committed to the personal efforts of each individual of the species; each of us has the prerogative of completing his inchoate and rudimental nature, and of developing his own perfection out of the living elements with which his mind began to be. It is his gift to be the creator of his own sufficiency; and to be emphatically self-made. This is the law of his being, which he cannot escape; and whatever is involved in that law he is bound, or rather he is carried on, to fulfil.
And here I am brought to the bearing of these remarks upon my subject. For this law of progress is carried out by means of the acquisition of knowledge, of which inference and assent are the immediate instruments. Supposing, then, the advancement of our nature, both in ourselves individually and as regards the human family, is, to every one of us in his place, a sacred duty, it follows that that duty is intimately bound up with the right use of these two main instruments of fulfilling it. And as we do not gain the knowledge of the law of progress by any à priori view of man, but by looking at it as the interpretation which is provided by himself on a large scale in the ordinary action of his intellectual nature, so too we must appeal to himself, as a fact, and not to any antecedent theory, in order to find what is the law of his mind as regards the two faculties in question. If then such an appeal does bear me out in deciding, as I have done, that the course of inference is ever more or less obscure, while assent is ever distinct and definite, and yet that what is in its nature thus absolute does, in fact follow upon what in outward manifestation is thus complex, indirect, and recondite, what is left to us but to take things as they are, and to resign ourselves to what we find? that is, instead of devising, what cannot be, some sufficient science of reasoning which may compel certitude in concrete conclusions, to confess that there is no ultimate test of truth besides the testimony born to truth by the mind itself, and that this phenomenon, perplexing as we may find it, is a normal and inevitable characteristic of the mental constitution of a being like man on a stage such as the world. His progress is a living growth, not a mechanism; and its instruments are mental acts, not the formulas and contrivances of language.
We are accustomed in this day to lay great stress upon the harmony of the universe; and we have well learned the maxim so powerfully inculcated by our own English philosopher, that in our inquiries into its laws, we must sternly destroy all idols of the intellect, and subdue nature by co-operating with her. Knowledge is power, for it enables us to use eternal principles which we cannot alter. So also is it in that microcosm, the human mind. Let us follow Bacon more closely than to distort its faculties according to the demands of an ideal optimism, instead of looking out for modes of thought proper to our nature, and faithfully observing them in our intellectual exercises.
Of course I do not stop here. As the structure of the universe speaks to us of Him who made it, so the laws of the mind are the expression, not of mere constituted order, but of His will. I should be bound by them even were they not His laws; but since one of their very functions is to tell me of Him, they throw a reflex light upon themselves, and, for resignation to my destiny, I substitute a cheerful concurrence in an overruling Providence. We may gladly welcome such difficulties as are to be found in our mental constitution, and in the interaction of our faculties, if we are able to feel that He gave them to us, and He can overrule them for us. We may securely take them as they are, and use them as we find them. It is He who teaches us all knowledge; and the way by which we acquire it is His way. He varies that way according to the subject-matter; but whether He has set before us in our particular pursuit the way of observation or of experiment, of speculation or of research, of demonstration or of probability, whether we are inquiring into the system of the universe, or into the elements of matter and of life, or into the history of human society and past times, if we take the way proper to our subject-matter, we have His blessing upon us, and shall find, besides abundant matter for mere opinion, the materials in due measure of proof and assent.
And especially, by this disposition of things, shall we learn, as regards religious and ethical inquiries, how little we can effect, however much we exert ourselves, without that Blessing; for, as if on set purpose, He has made this path of thought rugged and circuitous above other investigations, that the very discipline inflicted on our minds in finding Him, may mould them into due devotion to Him when He is found. "Verily Thou art a hidden God, the God of Israel, the Saviour," is the very law of His dealings with us. Certainly we need a clue into the labyrinth which is to lead us to Him; and who among us can hope to seize upon the true starting-points of thought for that enterprise, and upon all of them, who is to understand their right direction, to follow them out to their just limits, and duly to estimate, adjust, and combine the various reasonings in which they issue, so as safely to arrive at what it is worth any labour to secure, without a special illumination from Himself? Such are the dealings of Wisdom with the elect soul. "She will bring upon him fear, and dread, and trial; and She will torture him with the tribulation of Her discipline, till She try him by Her laws, and trust his soul. Then She will strengthen him, and make Her way straight to him, and give him joy."
§ 2. The Nature of the Illative Sense
IT is the mind that reasons, and that controls its own reasonings, not any technical apparatus of words and propositions. This power of judging and concluding, when in its perfection, I call the Illative Sense, and I shall best illustrate it by referring to parallel faculties, which we commonly recognize without difficulty.
