Milton in memorable words points out the transition which must take place from the gentleman of romance to the gentleman of enduring reality. After narrating how, in his youth, he betook himself "to those lofty fables and romances which recount in solemn cantos the deeds of knighthood founded by our victorious kings and thence had in renown through all Christendom," he says, "This my mind gave me that every free and gentle spirit, without that oath ought to be born a knight, nor needed to expect a gilt spur or the laying on of a sword upon his shoulder."

GENIAL critic detects a note of exaggeration in my praise of Ignorance. It is, he declares, a bit of "Yellow Journalism." The reader's attention is attracted by a glaring headline which leads him to suppose that a crime has been committed, when in reality nothing out of the ordinary has happened. That a person who has emerged from the state of absolute illiteracy far enough to appear in print should express a preference for Ignorance would be important if true. After perusing the chapter, however, he is of the opinion that it is not Ignorance, at all, that is described, but something much more respectable. It is akin to a state of mind which literary persons have agreed to praise under the name of Culture.

It is very natural that these literary persons should prefer a high-sounding name, and one free from vulgar associations, but I do not think that their plea will stand the test of scientific analysis. Science will not tolerate half knowledge nor pleasant imaginings, nor sympathetic appreciations; it must have definite demonstration. The knowledge of the best that has been said and thought may be very consoling, but it implies an unscientific principle of selection. It can be proved by statistics that the best things are exceptional. What about the second best, not to speak of the tenth rate? It is only when you have collected a vast number of commonplace facts that you are on the road to a true generalization.

In the Smithsonian Institution at Washington there is a children's room, in which there is a case marked "Pretty Shells." The specimens fully justify the inscription. The very daintiest shapes, and the most intricate convolutions, and the most delicate tints are represented. They are pretty shells, which have not left their beauty on the shore. But the delight in all this loveliness is not scientific. The kind gentleman who arranged the shells according to this classification acted not in his capacity as a conchologist, but as the father of a family.

Nor does the enjoyment of the most beautiful thoughts or words satisfy the requirements of those sciences which deal with humanity. The distinction between Literature and Science is fundamental. What is a virtue in one sphere is a vice in the other. After all that has been said about the scientific use of the imagination it remains true that the imagination is an intruder in the laboratory. Even if it were put to use, that would only mean that it is reduced to a condition of slavery. In its own realm it is accustomed to play rather than to work. It is also true that the attempts to introduce the methods of the laboratory into literature have been dismal failures. That way dullness lies.

Now and then, indeed, Nature in a fit of prodigality endows one person with both gifts.—Was not Oliver Wendell Holmes a Professor of Anatomy? In such a case there is a perpetual effervescence. But even Dr. Holmes could not insinuate a sufficient knowledge of Anatomy by means of a series of discursive essays; nor could he give scientific value to the reflections of the "Autocrat of the Breakfast Table."

There was a time when the ability to read was such a rare accomplishment that it seemed to furnish the key to all knowledge. Men of the baser sort had to learn by experience, but the reader followed a royal path to the very fountain head of wisdom. Ordinary rules were not for him; he could claim the benefit of clergy. Only a generation ago young men of parts prepared themselves for the bar—and very good lawyers they made—by "reading Blackstone." Blackstone is a pleasant author, with a fund of wise observations, and many pleasant afternoons were spent in his company. In like manner other young men "read medicine."
