The air we breathe, so long as it is neither too hot nor cold, nor rough, nor full of smoke—that is to say, so long as it is in that state within which we are best acquainted—seldom enters into our thoughts; yet there is hardly anything with which we are more incessantly occupied night and day.
Indeed, it is not too much to say that we have no really profound knowledge upon any subject—no knowledge on the strength of which we are ready to act at all moments unhesitatingly without either preparation or after-thought—till we have left off feeling conscious of the possession of such knowledge, and of the grounds on which it rests. A lesson thoroughly learned must be like the air which feels so light, though pressing so heavily against us, because every pore of our skin is saturated, so to speak, with it on all sides equally. This perfection of knowledge sometimes extends to positive disbelief in the thing known, so that the most thorough knower shall believe himself altogether ignorant. No thief, for example, is such an utter thief—so good a thief—as the kleptomaniac. Until he has become a kleptomaniac, and can steal a horse as it were by a reflex action, he is still but half a thief, with many unthievish notions still clinging to him. Yet the kleptomaniac is probably unaware that he can steal at all, much less that he can steal so well. He would be shocked if he were to know the truth. So again, no man is a great hypocrite until he has left off knowing that he is a hypocrite. The great hypocrites of the world are almost invariably under the impression that they are among the very few really honest people to be found and, as we must all have observed, it is rare to find any one strongly under this impression without ourselves having good reason to differ from him.
Our own existence is another case in point. When we have once become articulately conscious of existing, it is an easy matter to begin doubting whether we exist at all. As long as man was too unreflecting a creature to articulate in words his consciousness of his own existence, he knew very well that he existed, but he did not know that he knew it. With introspection, and the perception recognised, for better or worse, that he was a fact, came also the perception that he had no solid ground for believing that he was a fact at all. That nice, sensible, unintrospective people who were too busy trying to exist pleasantly to trouble their heads as to whether they existed or no—that this best part of mankind should have gratefully caught at such a straw as “cogito ergo sum,” is intelligible enough. They felt the futility of the whole question, and were thankful to one who seemed to clench the matter with a cant catchword, especially with a catchword in a foreign language; but how one, who was so far gone as to recognise that he could not prove his own existence, should be able to comfort himself with such a begging of the question, would seem unintelligible except upon the ground of sheer exhaustion.
At the risk of appearing to wander too far from the matter in hand, a few further examples may perhaps be given of that irony of nature, by which it comes about that we so often most know and are, what we least think ourselves to know and be—and on the other hand hold most strongly what we are least capable of demonstrating.
Take the existence of a Personal God,—one of the most profoundly-received and widely-spread ideas that have ever prevailed among mankind. Has there ever been a demonstration of the existence of such a God as has satisfied any considerable section of thinkers for long together? Hardly has what has been conceived to be a demonstration made its appearance and received a certain acceptance as though it were actual proof, when it has been impugned with sufficient success to show that, however true the fact itself, the demonstration is naught. I do not say that this is an argument against the personality of God; the drift, indeed, of the present reasoning would be towards an opposite conclusion, inasmuch as it insists upon the fact that what is most true and best known is often least susceptible of demonstration owing to the very perfectness with which it is known; nevertheless, the fact remains that many men in many ages and countries—the subtlest thinkers over the whole world for some fifteen hundred years—have hunted for a demonstration of God’s personal existence; yet though so many have sought,—so many, and so able, and for so long a time—none have found. There is no demonstration which can be pointed to with any unanimity as settling the matter beyond power of reasonable cavil. On the contrary, it may be observed that from the attempt to prove the existence of a personal God to the denial of that existence altogether, the path is easy. As in the case of our own existence, it will be found that they alone are perfect believers in a personal Deity and in the Christian religion who have not yet begun to feel that either stands in need of demonstration. We observe that most people, whether Christians, or Jews, or Mohammedans, are unable to give their reasons for the faith that is in them with any readiness or completeness; and this is sure proof that they really hold it so utterly as to have no further sense that it either can be demonstrated or ought to be so, but feel towards it as towards the air which they breathe but do not notice. On the other hand, a living prelate was reported in the “Times” to have said in one of his latest charges: “My belief is that a widely extended good practice must be founded upon Christian doctrine.” The fact of the Archbishop’s recognising this as among the number of his beliefs is conclusive evidence with those who have devoted attention to the laws of thought, that his mind is not yet clear as to whether or no there is any connection at all between Christian doctrine and widely extended good practice.

Again, it has been often and very truly said that it is not the conscious and self-styled sceptic, as Shelley for example, who is the true unbeliever. Such a man as Shelley will, as indeed his life abundantly proves, have more in common than not with the true unselfconscious believer. Gallio again, whose indifference to religious animosities has won him the cheapest immortality which, so far as I can remember, was ever yet won, was probably if the truth were known, a person of the sincerest piety. It is the unconscious unbeliever who is the true infidel, however greatly he would be surprised to know the truth. Mr. Spurgeon was reported as having recently asked the Almighty to “change our rulers as soon as possible.” There lurks a more profound distrust of God’s power in these words than in almost any open denial of His existence.
So it rather shocks us to find Mr. Darwin writing (“Plants and Animals under Domestication,” vol. ii., p. 275): “No doubt, in every case there must have been some exciting cause.” And again, six or seven pages later: “No doubt, each slight variation must have its efficient cause.” The repetition within so short a space of this expression of confidence in the impossibility of causeless effects would suggest that Mr. Darwin’s mind at the time of writing was, unconsciously to himself, in a state of more or less uneasiness as to whether effects could not occasionally come about of themselves, and without cause of any sort,—that he may have been standing, in fact, for a short time upon the brink of a denial of the indestructibility of force and matter.
In like manner, the most perfect humour and irony is generally quite unconscious. Examples of both are frequently given by men whom the world considers as deficient in humour; it is more probably true that these persons are unconscious of their own delightful power through the very mastery and perfection with which they hold it. There is a play, for instance, of genuine fun in some of the more serious scientific and theological journals which for some time past we have looked for in vain in “—.”
The following extract, from a journal which I will not advertise, may serve as an example:
“Lycurgus, when they had abandoned to his revenge him who had put out his eyes, took him home, and the punishment he inflicted upon him was sedulous instructions to virtue.” Yet this truly comic paper does not probably know that it is comic, any more than the kleptomaniac knows that he steals, or than John Milton knew he was a humorist when he wrote a hymn upon the circumcision, and spent his honeymoon in composing a treatise on divorce. No more again did Goethe know how exquisitely humorous he was when he wrote, in his Wilhelm Meister, that a beautiful tear glistened in Theresa’s right eye, and then went on to explain that it glistened in her right eye and not in her left, because she had had a wart on her left which had been removed—and successfully. Goethe probably wrote this without a chuckle; he believed what a good many people who have never read Wilhelm Meister believe still, namely, that it was a work full of pathos, of fine and tender feeling; yet a less consummate humorist must have felt that there was scarcely a paragraph in it from first to last the chief merit of which did not lie in its absurdity.
