Precept has generally been posterior to performance. The art of composing works of genius has never been taught but by the example of those who performed it by natural vigour of imagination, and rectitude of judgment. As we have few letters, we have likewise few criticisms upon the epistolary style. The observations with which Walsh has introduced his pages of inanity, are such as give him little claim to the rank assigned him by Dryden among the criticks. _Letters_, says he, _are intended as resemblances of conversation, and the chief excellencies of conversation are good humour and good breeding_. This remark, equally valuable for its novelty and propriety, he dilates and enforces with an appearance of complete acquiescence in his own discovery. No man was ever in doubt about the moral qualities of a letter. It has been always known that he who endeavours to please must appear pleased, and he who would not provoke rudeness must not practise it. But the question among those who establish rules for an epistolary performance is how gaiety or civility may be properly expressed; as among the criticks in history it is not contested whether truth ought to be preserved, but by what mode of diction it is best adorned. As letters are written on all subjects, in all states of mind, they cannot be properly reduced to settled rules, or described by any single characteristick; and we may safely disentangle our minds from critical embarrassments, by determining that a letter has no peculiarity but its form, and that nothing is to be refused admission, which would be proper in any other method of treating the same subject. The qualities of the epistolary style most frequently required, are ease and simplicity, an even flow of unlaboured diction, and an artless arrangement of obvious sentiments. But these directions are no sooner applied to use, than their scantiness and imperfection become evident. Letters are written to the great and to the mean, to the learned and the ignorant, at rest and in distress, in sport and in passion. Nothing can be more improper than ease and laxity of expression, when the importance of the subject impresses solicitude, or the dignity of the person exacts reverence. That letters should be written with strict conformity to nature is true, because nothing but conformity to nature can make any composition beautiful or just. But it is natural to depart from familiarity of language upon occasions not familiar. Whatever elevates the sentiments will consequently raise the expression; whatever fills us with hope or terrour, will produce some perturbation of images and some figurative distortions of phrase. Wherever we are studious to please, we are afraid of trusting our first thoughts, and endeavour to recommend our opinion by studied ornaments, accuracy of method, and elegance of style.
