In those long sentences rich in involved parenthesis, like a box of boxes one within another, and padded out like roast geese stuffed with apples, it is really the _memory_ that is chiefly taxed; while it is the understanding and the judgment which should be called into play, instead of having their activity thereby actually hindered and weakened.[1] This kind of sentence furnishes the reader with mere half-phrases, which he is then called upon to collect carefully and store up in his memory, as though they were the pieces of a torn letter, afterwards to be completed and made sense of by the other halves to which they respectively belong. He is expected to go on reading for a little without exercising any thought, nay, exerting only his memory, in the hope that, when he comes to the end of the sentence, he may see its meaning and so receive something to think about; and he is thus given a great deal to learn by heart before obtaining anything to understand. This is manifestly wrong and an abuse of the reader's patience.
[Footnote 1: _Translator's Note._--This sentence in the original is obviously meant to illustrate the fault of which it speaks. It does so by the use of a construction very common in German, but happily unknown in English; where, however, the fault itself exists none the less, though in different form.]
The ordinary writer has an unmistakable preference for this style, because it causes the reader to spend time and trouble in understanding that which he would have understood in a moment without it; and this makes it look as though the writer had more depth and intelligence than the reader. This is, indeed, one of those artifices referred to above, by means of which mediocre authors unconsciously, and as it were by instinct, strive to conceal their poverty of thought and give an appearance of the opposite. Their ingenuity in this respect is really astounding.
It is manifestly against all sound reason to put one thought obliquely on top of another, as though both together formed a wooden cross. But this is what is done where a writer interrupts what he has begun to say, for the purpose of inserting some quite alien matter; thus depositing with the reader a meaningless half-sentence, and bidding him keep it until the completion comes. It is much as though a man were to treat his guests by handing them an empty plate, in the hope of something appearing upon it. And commas used for a similar purpose belong to the same family as notes at the foot of the page and parenthesis in the middle of the text; nay, all three differ only in degree. If Demosthenes and Cicero occasionally inserted words by ways of parenthesis, they would have done better to have refrained.
