"It is impossible to deny that dishonest men often grow rich and famous, becoming powerful in their parish or in parliament. Their portraits simper from shop windows; and they live and die respected. This success is theirs; yet it is not the success which a noble soul will envy. Apart from the risk of discovery and infamy, there is the certainty of a conscience ill at ease, or if at ease, so blunted in its sensibilities, so given over to lower lusts, that a healthy instinct recoils from such a state. Observe, moreover, that in Literature the possible rewards of dishonesty are small, and the probability of detection great. In Life a dishonest man is chiefly moved by desires towards some tangible result of money or power; if he get these he has got all. The man of letters has a higher aim: the very object of his toil is to secure the sympathy and respect of men; and the rewards of his toil may be paid in money, fame, or consciousness of earnest effort. The first of these may sometimes be gained without Sincerity. Fame may also, for a time, be erected on an unstable ground, though it will inevitably be destroyed again. But the last and not least reward is to be gained by every one without fear of failure, without risk of change. Sincere work is good work, be it never so humble; and sincere work is not only an indestructible delight to the worker by its very genuineness, but is immortal in the best sense, for it lives for ever in its influence. There is no good Dictionary, not even a good Index, that is not in this sense priceless, for it has honestly furthered the work of the world, saving labour to others, setting an example to successors."

“No deeply-rooted tendency was ever extirpated by adverse argument. Not having originally been founded on argument, it cannot be destroyed by logic.”

“I would not have the reader conclude that because I advocate plain-speaking even of unpopular views, I mean to imply that originality and sincerity are always in opposition to public opinion. There are many points both of doctrine and feeling in which the world is not likely to be wrong. But in all cases it is desirable that men should not pretend to believe opinions which they really reject, or express emotions they do not feel. And this rule is universal. Even truthful and modest men will sometimes violate the rule under the mistaken idea of being eloquent by means of the diction of eloquence. This is a source of bad Literature.”

“The first obligation of Simplicity is that of using the simplest means to secure the fullest effect. But although the mind instinctlvely rejects all needless complexity, we shall greatly err if we fail to recognise the fact, that what the mind recoils from is not the complexity, but the needlessness.”

“Obedient to the primary impulse of adequate expression, the style of a complex subject should be complex; of a technical subject, technical; of an abstract subject, abstract; of a familiar subject, familiar; of a pictorial subject, picturesque.”

“The art of a great writer is seen in the perfect fitness of his expressions. He knows how to blend vividness with vagueness, knows where images are needed, and where by their vivacity they would be obstacles to the rapid appreciation of his thought.”

“Every one who has seriously investigated a novel question, who has really interrogated Nature with a view to a distinct answer, will bear me out in saying that it requires intense and sustained effort of imagination. The relations of sequence among the phenomena must be seen; they are hidden; they can only be seen mentally; a thousand suggestions rise before the mind, but they are recognised as old suggestions, or as inadequate to reveal what is sought; the experiments by which the problem may be solved have to be imagined; and to imagine a good experiment is as difficult as to invent a good fable, for we must have distinctly present — clear mental vision — the known qualities and relations of all the objects, and must see what will be the effect of introducing some new qualifying agent. If any one thinks this is easy, let him try it: the trial will teach him a lesson respecting the methods of intellectual activity not without its use.”
