As commentary we add that whether a certain propaganda is really vital and important is a question to be decided by the practical experience of mankind. The artist may be overwhelmingly convinced that his particular propaganda is of supreme importance, whereas the experience of the race may prove that it is of slight importance; therefore, what was supposed to be, and was for centuries taken to be a sublime work of art, turns out to be a piece of trumpery and rubbish. But let the artist in the labor of his spirit and by the stern discipline of hard thinking, find a real path of progress for the race; let him reveal new impulses for men to thrill to, new perils for them to overcome, new sacrifices for them to make, new joys for them to experience; let him make himself master of the technique of any one of the arts, and put that propaganda adequately and vitally before his fellows--and so, and so alone, he may produce real and enduring works of art. POSTSCRIPT Manifestly, all this depends upon the meaning given to the term propaganda. The writer thought that he could trust his critics to look it up in the dictionary; but during the serial publication of the book he discovered that the critics share that false idea of the word which was brought into fashion during the World War--this idea being itself a piece of propaganda. Our own martial fervor was of course not propaganda, it was truth and justice; but there crept in an evil enemy thing, known as “German propaganda”; and so the word bears a stigma, and when this book applies it to some honorable variety of teaching, the critics say that we are “stretching its meaning,” and being absurd. But all we are doing is to use the word correctly. The Standard Dictionary defines propaganda as: “Effort directed systematically toward the gaining of support for an opinion or course of action.” This, you note, contains no suggestion of reprobation. Propaganda may be either good or bad, according to the nature of the teaching and the motives of the teacher. The Jesuits have been carrying on a propaganda of their faith for three hundred years, and one does not have to share this faith in order to admit their right to advocate it. The present writer has for twenty-one years been carrying on a propaganda for Socialism, and has a sturdy conviction that his time has not been wasted. We take certain opinions and courses of action for granted; they come to us easily, and when in a poem or other work of art we encounter the advocacy of such things, it does not seem to us propaganda. Take, for example, that favorite theme of poets, the following of our natural impulses; it is pleasant to do this, and the poet who gives such advice awakens no opposition. But it is different in the case of ideas which require concentration of the attention and effort of will; such ideas trouble and repel us, we resent them, and the term “propaganda” is our expression of resentment. For example, the old poet Herrick advises:
