In what way diction should answer to man's inner nature. First, the grounds of the natural disaffection with unusual diction: how far this should be observed.
But it is not sufficient that diction answer to the subject-matter unless it also answers to the nature of man, in which may be discerned a kind of aversion to obsolete, low, and inappropriate words. I prefer to call this aversion a natural one rather than a result of opinion, though it is in a way based on opinion. For although the feeling that a particular word is more in common use and more civilized than another is purely a matter of men's judgement, nevertheless it is as natural to be displeased by the unusual and inappropriate as it is to be pleased with the usual and proper. Whatever is contrary to reason offends by the very fact that it is seen to lack reason. Certainly, to leave aside familiar terms and to search out unusual ones is wholly foreign to reason. However, there is added to this natural source of offense another that proceeds from opinion. Since such words are commonly condemned, there is associated with them a certain distaste and contempt such that it is scarcely possible to pronounce them without immediately arousing the associated feelings.
Consequently, the intelligent writer will willingly comply with usage so as not to give grounds for displeasure—whether this displeasure springs from nature or opinion. Though he is aware that usage is unstable and changes day by day, nevertheless he will prefer rather to please at one time than never. He will be careful, however, in his written work not to make use of the current jargon, especially of the French court and women's circles, or of any locutions that are not yet generally received. For the life of such expressions is too short to be bound into a lasting work—not to speak of the detestable affectation which detracts from the weight and dignity of the writing.
To conclude, there is a beauty and charm in propriety and elegance of diction which is not to be scorned, though it is but of a time, and, since it rests on opinion, by which usage is determined, will pass away with a change of opinion. Hence those who write not for an age but for all time should try to attain something else, something that has no admixture of opinion: Such is the agreement of words with nature, which we will now explain.
