It must have occurred to every serious person that the pursuit of knowledge is not what it once was. Time was when to know seemed the easiest thing in the world. All that a man had to do was to assert dogmatically that a thing was so, and then argue it out with some one who had even less acquaintance with the subject than he had. He was not hampered by a rigid, scientific method, nor did he need to make experiments, which after all might not strengthen his position. The chief thing was a certain tenacity of opinion which would enable him, in Pope's phrase, to "hold the eel of science by the tail." There were no troublesome experts to cast discredit on this slippery sport. If a man had a knack at metaphysics and a fine flow of technical language he could satisfy all reasonable curiosity about the Universe. Or with the minimum of effort he might attain a jovial scholarship adequate for all convivial purposes, like Chaucer's pilgrim
| "Whan that he wel dronken had the win, |
| Than wold he speken no word but Latin." |
It was the golden age of the amateur, when certainty could be had for the asking, and one could stake out any part of the wide domain of human interest and hold it by the right of squatter sovereignty. But in these days the man who aspires to know must do something more than assert his conviction. He must submit to all sorts of mortifying tests, and at best he can obtain a title to only the tiniest bit of the field he covets.
With the severer definitions of knowledge and the delimitation of the territory which any one may call his own there has come a curious result. While the aggregate of intellectual wealth has increased, the individual workers are being reduced to penury. It is a pathetic illustration of Progress and Poverty. The old and highly respected class of gentlemen and scholars is being depleted. Scholarship has become so difficult that those who aspire after it have little time for the amenities. It is not as it was in the "spacious times of great Elizabeth." Enter any company of modern scholars and ask what they know about any large subject, and you will find that each one hastens to take the poor debtor's oath. How can they be expected to know so much?
On this minute division of intellectual labor the exact sciences thrive, but conversation, poetry, art, and all that belongs to the humanities languish.
Your man of highly specialized intelligence has often a morbid fear of half-knowledge, and he does not dare to express an opinion that has not been the result of original research. He shuns the innocent questioners who would draw him out, as if they were so many dunning creditors. He becomes a veritable Dick Swiveller as one conversational thoroughfare after another is closed against him, until he no longer ventures abroad. The worst of it is that he has a haunting apprehension that even the bit of knowledge which he calls his own may be taken away from him by some new discovery, and he may be cast adrift upon the Unknowable.
It is then that he should remember the wisdom of the unjust steward, so that when he is cast out of the House of Knowledge he may find congenial friends in the habitations of Ignorance.
There are a great many mental activities that stop short of strict knowledge. Where we do not know, we may imagine, and hope, and dare; we may laugh at our neighbor's mistakes, and occasionally at our own. We may enjoy the delicious moments of suspense when we are on the verge of finding out; and if it should happen that the discovery is postponed, then we have a chance to go over the delightful process again.
To say "I do not know" is not nearly as painful as it seems to those who have not tried it. The active mind, when the conceit of absolute knowledge has been destroyed, quickly recovers itself and cries out, after the manner of Brer Rabbit when Brer Fox threw him into the brier patch, "Bred en bawn in a brier patch, Brer Fox—bred en bawn in a brier patch!"
