To some men popularity is always suspicious. Enjoying none themselves, they are prone to suspect the validity of those attainments which command it. - George Henry Lewes

The great desire of this age is for a Doctrine which may serve to condense our knowledge, guide our researches, and shape our lives, so that Conduct may really be the consequence of Belief.

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.

In Science the paramount appeal is to the Intellect — its purpose being instruction; in Art, the paramount appeal is to the Emotions — its purpose being pleasure. A work of Art must of course indirectly appeal to the Intellect, and a work of Science will also indirectly appeal to the Feelings; nevertheless a poem on the stars and a treatise on astronomy have distinct aims and distinct methods. But having recognised the broadly-marked differences, we are called upon to ascertain the underlying resemblances. Logic and Imagination belong equally to both. It is only because men have been attracted by the differences that they have overlooked the not less important affinities.
