Science is the systematic classification of experience. - George Henry Lewes

The history of the race is but that of the individual "writ large".

Minds differ in the vividness with which they recall the elements of previous experience, and mentally see the absent objects; they differ also in the aptitudes for selection, abstraction, and recombination: the fine selective instinct of the artist, which makes him fasten upon the details which will most powerfully affect us, without any disturbance of the harmony of the general impression, does not depend solely upon the vividness of his memory and the clearness with which the objects are seen, but depends also upon very complex and peculiar conditions of sympathy which we call genius.

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.
