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

I wish to guard the Principle of Vision from certain misconceptions which might arise on a simple statement of it. The principle insists on the artist assuring himself that he distinctly sees what he attempts to represent. What he sees, and how he represents it, depend on other principles. To make even this principle of Vision thoroughly intelligible in its application to all forms of Literature and Art, it must be considered in connection with the two other principles — Sincerity and Beauty, which are involved in all successful works.

An artist produces an effect in virtue of the distinctness with which he sees the objects he represents, seeing them not vaguely as in vanishing apparitions, but steadily, and in their most characteristic relations. To this Vision he adds artistic skill with which to make us see. He may have clear conceptions, yet fail to make them clear to us: in this case he has imagination, but is not an artist. Without clear Vision no skill can avail. Imperfect Vision necessitates imperfect representation; words take the place of ideas.

Literature is at once the cause and the effect of social progress. It deepens our natural sensibilities, and strengthens by exercise our intellectual capacities. It stores up the accumulated experience of the race, connecting Past and Present into a conscious unity; and with this store it feeds successive generations, to be fed in turn by them. As its importance emerges into more general recognition, it necessarily draws after it a larger crowd of servitors, filling noble minds with a noble ambition.
