the principal effects of poetry are reproduced with greater intensity. Thus the contemplation and meditation suggested by Art, besides their own intrinsic charm, will prepare the way for the exercise of similar faculties in Science. For with the individual, as with the species, the combination of images will assist the combination of signs: signs in their origin being images which have lost their vividness. As the sphere of Art includes every subject of human interest, we shall become familiarized, during the esthetic period of education, with the principal conceptions that are afterwards to be brought before us systematically in the scientific period. Especially will this be true of historical studies. By the time that the pupil enters upon them, he will be already familiar with poetic descriptions of the various social phases, and of the men who played a leading part in them. [Relation of Art to Religion] And if Art is of such importance in the education of the young, it is no less important in the afterwork of education; the work of recalling men or classes of men to those high feelings and principles which, in the daily business of life, are so apt to be forgotten. In the solemnities, private or public, appointed for this purpose, Positivism will rely far more on impressions such as poetry can inspire, than on scientific explanations. Indeed the preponderance of Art over Science will be still greater than in education properly so called. The scientific basis of human conduct having been already laid down, it will not be necessary to do more than refer to it. The philosophic priesthood will in this case be less occupied with new conceptions, than with the enforcement of truth already known, which demands esthetic rather than scientific talent.
