Looking at the two essential functions of the spiritual power, education and counsel, it is not difficult to see that what they require is a combination of poetic feeling with scientific insight. We look for a measure of both these qualities in the public; therefore men who are devoid of either of them cannot be fit to be its spiritual guides. That they take the name of philosophers in preference to that of poets, is because their ordinary duties are more connected with Science than with Art but they ought to be equally interested in both. Science requires systematic teaching, whereas Art is cultivated spontaneously, with the exception of the technical branches of the special arts. It must be remembered that the highest esthetic functions are not such as can be performed continuously. It is only works of rare excellence which are in the highest sense useful: these, once produced, supply an unfailing source of idealization and expression for our emotions, whether in public or in private. It is enough, if the interpreter of these works and his audience have been so educated as to appreciate what is perfect, and reject mediocrity. Organs of unusual power will arise occasionally, as in former times, from all sections of society, whenever the need of representing new emotions may be felt. But they will come more frequently from the philosophic class in whose character, when it is fully developed, Sympathy will be as prominent a feature as System.
