Maeterlinck has realised, better than any one else, the significance, in life and art, of mystery. He has realised how unsearchable is the darkness out of which we have but just stepped, and the darkness into which we are about to pass. And he has realised how the thought and sense of that twofold darkness invade the little space of light in which, for a moment, we move; the depth to which they shadow our steps, even in that moment's partial escape. But in some of his plays he would seem to have apprehended this mystery as a thing merely or mainly terrifying; the actual physical darkness sur-rounding blind men, the actual physical approach of death as the intruder; he has shown us people huddled at a window, out of which they are almost afraid to look, or beating at a door, the opening of which they dread. Fear shivers through these plays, creeping across our nerves like a damp mist coiling up out of a valley. And there is beauty, certainly, in this "vague spiritual fear"; but a less obvious kind of beauty than that which gives its profound pathos to Aglavaine et Sélysette, the one play written since the writing of the essays. Here is mystery, which is also pure beauty, in these delicate approaches of intellectual pathos, in which suffering and death and error become transformed into something almost happy, so full is it of strange light.
And the aim of Maeterlinck, in his plays, is not only to render the soul and the soul's atmosphere, but to reveal this strangeness, pity, and beauty through beautiful pictures. No dramatist has ever been so careful that his scenes should be in themselves beautiful, or has made the actual space of forest, tower, or seashore so emotionally significant. He has realised, after Wagner, that the art of the stage is the art of pictorial beauty, of the correspondence in rhythm between the speakers, their words, and their surroundings. He has seen how, in this way, and in this way alone, the emotion, which it is but a part of the poetic drama to express, can be at once intensified and purified.
It is only after hinting at many of the things which he had to say in these plays, which have, after all, been a kind of subterfuge, that Maeterlinck has cared, or been able, to speak with the direct utterance of the essays. And what may seem curious is that this prose of the essays, which is the prose of a doctrine, is incomparably more beautiful than the prose of the plays, which was the prose of an art. Holding on this point a different opinion from one who was, in many senses, his master, Villiers de l'Isle-Adam, he did not admit that beauty of words, or even any expressed beauty of thoughts, had its place in spoken dialogue, even though it was not two living actors speaking to one another on the stage, but a soul speaking to a soul and imagined speaking through the mouths of marionettes. But that beauty of phrase which makes the profound and sometimes obscure pages of Axël shine as with the crossing fire of jewels, rejoices us, though with a softer, a more equable, radiance, in the pages of these essays, in which every sentence has the in-dwelling beauty of an intellectual emotion, preserved at the same height of tranquil ecstasy from first page to last. There is a sort of religious calm in these deliberate sentences, into which the writer has known how to introduce that divine monotony which is one of the accomplishments of great style. Never has simplicity been more ornate or a fine beauty more visible through its self-concealment.
But, after all, the claim upon us of this book is not the claim of a work of art, but of a doctrine, and more than that, of a system. Belonging, as he does, to the eternal hierarchy, the unbroken succession, of the mystics, Maeterlinck has apprehended what is essential in the mystical doctrine with a more profound comprehension, and thus more systematically, than any mystic of recent times. He has many points of resemblance with Emerson, on whom he has written an essay which is properly an exposition of his own personal ideas; but Emerson, who proclaimed the supreme guidance of the inner light, the supreme necessity of trusting instinct, of honouring emotion, did but proclaim all this, not without a certain anti-mystical vagueness: Maeterlinck has systematised it. A more profound mystic than Emerson, he has greater command of that which comes to him unawares, is less at the mercy of visiting angels.
Also, it may be said that he surrenders himself to them more absolutely, with less reserve and discretion; and, as he has infinite leisure, his contemplation being subject to no limits of time, he is ready to follow them on unknown rounds, to any distance, in any direction, ready also to rest in any wayside inn, without fearing that he will have lost the road on the morrow.
This old gospel, of which Maeterlinck is the new voice, has been quietly waiting until certain bankruptcies, the bankruptcy of Science, of the Positive Philosophies, should allow it full credit. Considering the length even of time, it has not had an unreasonable space of waiting; and remember that it takes time but little into account. We have seen many little gospels demanding of every emotion, of every instinct, "its certificate at the hand of some respectable authority." Without confidence in themselves or in things, and led by Science, which is as if one were led by one's note-book, they demand a reasonable explanation of every mystery. Not finding that explanation, they reject the mystery; which is as if the fly on the wheel rejected the wheel because it was hidden from his eyes by the dust of its own raising.
The mystic is at once the proudest and the humblest of men. He is as a child who resigns himself to the guidance of an unseen hand, the hand of one walking by his side; he resigns himself with the child's humility. And he has the pride of the humble, a pride manifesting itself in the calm rejection of every accepted map of the roads, of every offer of assistance, of every painted signpost pointing out the smoothest ways on which to travel. He demands no authority for the unseen hand whose fingers he feels upon his wrist. He conceives of life, not, indeed, so much as a road on which one walks, very much at one's own discretion, but as a blown and wandering ship, surrounded by a sea from which there is no glimpse of land; and he conceives that to the currents of that sea he may safely trust himself. Let his hand, indeed, be on the rudder, there will be no miracle worked for him; it is enough miracle that the sea should be there, and the ship, and he himself. He will never know why his hand should turn the rudder this way rather than that.
Jacob Boehme has said, very subtly, "that man does not perceive the truth but God perceives the truth in man"; that is, that whatever we perceive or do is not perceived or done consciously by us, but unconsciously through us. Our business, then, is to tend that "inner light" by which most mystics have symbolised that which at once guides us in time and attaches us to eternity. This inner light is no miraculous descent of the Holy Spirit, but the perfectly natural, though it may finally be overcoming, ascent of the spirit within us. The spirit, in all men, being but a ray of the universal fight, it can, by careful tending, by the removal of all obstruction, the cleansing of the vessel, the trimming of the wick, as it were, be increased, made to burn with a steadier, a brighter flame. In the last rapture it may become dazzling, may blind the watcher with excess of light, shutting him in within the circle of transfiguration, whose extreme radiance will leave all the rest of the world henceforth one darkness.
All mystics being concerned with what is divine in life, with the laws which apply equally to time and eternity, it may happen to one to concern himself chiefly with time seen under the aspect of eternity, to another to concern himself rather with eternity seen under the aspect of time. Thus many mystics have occupied themselves, very profitably, with showing how natural, how explicable on their own terms, are the mysteries of life; the whole aim of Maeterlinck is to show how mysterious all life is, "what an astonishing thing it is, merely to live." What he had pointed out to us, with certain solemn gestures, in his plays, he sets himself now to affirm, slowly, fully, with that "confidence in mystery" of which he speaks. Because "there is not an hour without its familiar miracles and its ineffable suggestions," he sets himself to show us these miracles and these meanings where others have not always sought or found them, in women, in children, in the theatre. He seems to touch, at one moment or another, whether he is discussing La Beauté Intérieure or Le Tragique Quotidien, on all of these hours, and there is no hour so dark that his touch does not illuminate it.
And it is characteristic of him, of his "confidence in mystery," that he speaks always without raising his voice, without surprise or triumph, or the air of having said anything more than the simplest observation. He speaks, not as if he knew more than others, or had sought out more elaborate secrets, but as if he had listened more attentively.
