He saw also that he must work out his dreams within the circle of his own limitations; and that his limitations were not the limitations of his fellow workers; neither were their limitations his. He did not know yet just where the outmost circle of his limitations lay but he knew that it was there and that he must make no mistake when he came to it. And this, too, is true: just to the degree that the man recognized his limitations, the circle widened.
Also the man came to understand that there are things knowable and things unknowable. He came to see that truest wisdom is in this: for one to spend well his strength on the knowable things and refuse to dissipate his intellectual vigor upon the unknowable. Not until he began really to know things was he conscious in any saving degree of the unknowable. He saw that those who strive always with the unknowable beat the air in vain and exhaust themselves in their senseless folly. He saw that to concern oneself wholly with the unknowable is to rob the world of the things in which are its life. To meditate much upon the unknowable is an intellectual dissipation that produces spiritual intoxication and often results in spiritual delirium tremens. A habitual spiritual drunkard is a nuisance in the world. The wisdom of Ignorance is in nothing more apparent than in a clear recognition of the unknowable.
And then the man came to regret knowing some of the things that he knew. He came, in some things, to wish with all his heart that he had Ignorance where he had Knowledge. He found that much of the time and strength that he desired to spend in acquiring the knowledge that would help him to work out his dreams, he must spend, instead, in ridding himself of knowledge that he had already acquired. He learned that to forget is quite as necessary as to remember and very often much more difficult. Young he was, and strong he was, but, already, he felt the dragging power of the things he would have been better for not knowing—the things he desired to forget. They were very little things in comparison to the things that in the future he would wish to forget; but to him, at this time, they did not seem small. So it was that, in his effort to acquire Knowledge, the man began to strive also for Ignorance.
I do not know what it was that the man had learned that he desired to forget. My story is not the kind of a story that tells those things. I know, only, that for him to forget was imperative. I know, only, that had he held fast to Ignorance in some things of which he had gained knowledge, it would have been better. For him in some things Ignorance would have been the truest wisdom. Ignorance would have helped him to work out his dreams when Knowledge only hindered by forcing him to spend much time striving to forget. Those who know too much of evil find it extremely difficult to gain knowledge of the good. Those who know too much of the false find it very hard to recognize the true. A too great knowledge of things that are wrong makes it almost impossible for one to believe in that which is right. Ignorance, rightly understood, is, indeed, one of the Thirteen Truly Great Things of Life.
And then this man, in learning the value of Ignorance, came perilously near believing that no man could know anything. He came dangerously near the belief that Knowledge is all a mirage toward which men journey hopelessly; a phantom to be grasped by no hand; a will-o'-the-wisp to be followed here and there but leading nowhere. He, for a little, said that Ignorance is the truest wisdom. He believed, for a time, that to say always: "I do not know," is the height of all intelligence. One by one, he saw his intellectual idols fall in the dust of the commonplace. Little by little, he discovered that the intellectual masters he had served were themselves only servants. His intellectual Gods, he found to be men like himself. And so, for a while, he said: "We can know nothing. We can only think that we know. We can only pretend to know. There is no real Knowledge but only Ignorance. Ignorance should be exalted. In Ignorance lies peace, contentment, happiness, and safety." Even of his work—of his dreams he said this. He said: "It is no use." To the very edge of this pit he came but he did not fall in.
To accept the fact of the unknowable without losing his faith in the knowable: to recognize the unknown without losing in the least his grip upon the known: to find the Knowledge of Yesterday becoming the Ignorance of to-day and still hold fast to the Knowledge of the present; to watch his intellectual leaders dropping to the rear and to follow as bravely those who were still in the front: to see his intellectual heroes fall and his intellectual idols crumbling in the dust and still to keep burning the fire of his enthusiasm: to find Knowledge so often a curse and Ignorance a blessing and still to desire Knowledge: all this, the man learned that he must do if he would work out his dreams. That which saved the man from the pit of hopeless disbelief in everything and helped him to a clear understanding of Ignorance, was this: he went back again into his Yesterdays.
From sheltered fence corners and hidden woodland hollows, from the lee of high banks, and along the hedge in the garden, the last worn and ragged remnant of winter's garment was gone. The brook in the valley, below the little girl's house, had broken the last of its fetters and was rejoicing boisterously in its freedom. The meadow and pasture lands showed the tender green of the first grass life. Pussy willow buds were swelling and over the orchard and the wood a filmy veil of summer color was dropped as though by fairy hands. In the cherry tree, a pair of brown birds, just returning from their southern home, were discussing the merits of the nearby hedge as a building site: the madam bird insisting, as women will, that the beautiful traditions of the spot made it, for home building, peculiarly desirable. It was a well known fact, said she, that brown birds had builded there for no one knows how many ages. Even in the far away city, the man felt the season in the air. The reek of city odors could not altogether drown the subtle perfume that betrayed the near presence of the spring. As though the magic of the budding, sprouting, starting, time of the year placed him under its spell, the man went back to the springtime of his life—back into his Yesterdays.
Once again, he walked under the clear skies of childhood. Once again, he lived in the blessed, blessed, days when he had nothing to forget—when his mind and life were as a mountain brook that, clear and pure, from the spring of its birth runs ever onward, outward, turning never back, pausing never to form stagnant, poisonous, pools. And there it was—in his Yesterdays—in the pure sunlight of childhood—that he found new intellectual faith—that he came to a right understanding of the real wisdom of Ignorance.
The intellectual giants of his Yesterdays—those wise ones upon whose learning he looked with childish awe—who were they? Famous scholars who lectured in caps and gowns and words of many syllables upon themes of mighty interest to themselves? Students who, in their laboratory worlds, discovered many wonderful things that were not so and solved many puzzling problems with solutions that were right and entirely satisfactory until the next graduating class discovered them to be all wrong and no solution at all? Great religious leaders who were supernaturally called, divinely commissioned, and armed with holy authority to point out the true and only way of life until some other with the same call, commission, and authority, pointed out a wholly different true and only way? Great statesmen upon whose knowledge and leadership the salvation of the nation depended, until the next election discovered them to be foolish puppets of a dishonest and corrupt party and put new leaders in their places to save the nation with a new brand of political salvation, the chief value of which was its newness? No indeed! Such as these were not the intellectual giants of the man's Yesterdays. The heights of knowledge in those days were held by others than these.
One of the very highest peaks in the whole mountain range of learning, in the Yesterdays, was held by the hired man. Again, at chore time, the boy followed this wise one about the stables and the barn, watching, from a safe position near the door, while the horses were groomed and bedded down for the night. Again the pungent odors from the stalls, the scent of the straw and the hay in the loft, the smell of harness leather damp with sweat was in his nostrils and in his ears, the soft swish of switching tails, the thud of stamping hoofs, the contented munching of grain, the rustle of hay, with now and then a low whinny or an angry squeal. And fearlessly to and fro in this strange world moved the hired man. In and out among the horses he passed, perfectly at home in the stalls, seeming to share the most intimate secrets of the horse life.
