In these encounters the learning of the recluse usually fails him: nothing but long habit and frequent experiments can confer the power of changing a position into various forms, presenting it in different points of view, connecting it with known and granted truths, fortifying it with intelligible arguments, and illustrating it by apt similitudes; and he, therefore, that has collected his knowledge in solitude, must learn its application by mixing with mankind.

But while the various opportunities of conversation invite us to try every mode of argument, and every art of recommending our sentiments, we are frequently betrayed to the use of such as are not in themselves strictly defensible: a man heated in talk, and eager of victory, takes advantage of the mistakes or ignorance of his adversary, lays hold of concessions to which he knows he has no right, and urges proofs likely to prevail on his opponent, though he knows himself that they have no force: thus the severity of reason is relaxed, many topicks are accumulated, but without just arrangement or distinction; we learn to satisfy ourselves with such ratiocination as silences others; and seldom recall to a close examination, that discourse which has gratified our vanity with victory and applause.

Some caution, therefore, must be used lest copiousness and facility be made less valuable by inaccuracy and confusion. To fix the thoughts by writing, and subject them to frequent examinations and reviews, is the best method of enabling the mind to detect its own sophisms, and keep it on guard against the fallacies which it practises on others: in conversation we naturally diffuse our thoughts, and in writing we contract them; method is the excellence of writing, and unconstraint the grace of conversation.

To read, write, and converse in due proportions, is, therefore, the business of a man of letters. For all these there is not often equal opportunity; excellence, therefore, is not often attainable; and most men fail in one or other of the ends proposed, and are full without readiness, or without exactness. Some deficiency must be forgiven all, because all are men; and more must be allowed to pass uncensured in the greater part of the world, because none can confer upon himself abilities, and few have the choice of situations proper for the improvement of those which nature has bestowed: it is, however, reasonable to have perfection in our eye; that we may always advance towards it, though we know it never can be reached.
