Compare with the sentence just given, this passage from an undergraduate’s theme:—
Chaucer’s influence on the language was great, and he helped to put the language before the people in a way that had not been done before, so that it is evident that there was a great result from this. This was because he helped to change the English language, and in this way he was very influential in affecting the language.
Here an unhappy youth, engaged in all but mortal combat with an examination paper, was endeavoring to say something when he had nothing to say. Of course he could not but fail, since it is impossible to show clearly what one does not see clearly.
With these put also this, which again is from an undergraduate’s theme:—
If the student respects a professor, as many do, he can show his respect in many ways; if he does not, and there are teachers who do not command the respect of students (I do not consider the question to be confined to this school, and in some colleges there are men on the Faculty who are not respected, nor do they deserve to be) and I think a man should raise his hat only to ladies or to gentlemen that have ladies with them.
Here the writer knew fairly well what he wished to say, although he had not taken the trouble to think it out very sharply. His difficulty was that he lacked technical skill in expression.
These examples illustrate the causes from which obscurity may arise. The first is legitimate. Whether we agree that Carlyle or George Meredith or Browning has carried obscurity beyond the farthest limit at which it is permissible has nothing to do with the fact that there are times when it is the right of an author to sacrifice Clearness to some other effect which he seeks. It is, however, fair to say that in ordinary experience these emergencies are pretty nearly as rare as the appearance of white blackbirds; and that at least no writer has a right to discard Clearness until he has secured it. Certainly no one can successfully employ obscurity as a means of producing literary effect until he has acquired the art of writing with transparent simplicity.
Of the second cause it is sufficient to say here that no outward aid can enable the student to overcome it. To think sharply and lucidly is the result of self-discipline. It is a matter of mental exercise, and while a student may be sent to a mental as to a physical gymnasium, all strengthening of the mind as of the muscles must be the result of individual exertion. There has as yet been discovered no system of intellectual massage, by means of which the understanding may attain to the benefits of work without doing anything.
While rules or wise maxims help little in this matter of mental clearness, it is a thing so important and so universally essential in all intellectual training that it is difficult to pass it without a word more. If a new Dante were to people a new Inferno with sinners guilty of crimes intellectual, as the stern old Florentine peopled his with those who violated moral laws, the most populous circle would be devoted to those who mistakenly think themselves to think. There is a discouragingly large portion of mankind whose mental processes are apparently those of the oyster. They are mentally so indolent or incapable that the labor of reflecting is entirely beyond them. No student can afford to remain in doubt as to whether he really thinks, or merely indulges in vague mental impressions which are to genuine thought as is the dull smouldering of a heap of wet leaves in a November fog to a brisk beech-wood fire on a wide hearth in a winter night.
