There is an excellent custom prevalent among the working men of France and creditable to their good sense, with which our educational scheme seems at first sight incompatible. I refer to the custom of travelling from place to place during the last years of apprenticeship; which is as beneficial to their mind and character, as the purposeless excursions of our wealthy and idle classes are in most cases injurious. But there is no necessity for its interfering with study, since it always involves long residence in the chief centres of production, where the workman is sure to find annual courses of lectures similar to those which he would otherwise have been attending at home. As the structure and distribution of the philosophic body will be everywhere the same, there need be no great inconvenience in these changes. For every centre not more than seven teachers will be required; each of whom will take the whole Encyclopædic scale successively. Thus the total number of lectures will be so small as to admit of a high standard of merit being everywhere attained, and of finding everywhere a fair measure of material support. So far from discouraging the travelling system, Positivism will give it a new character, intellectually and socially, by extending the range of travel to the whole of Western Europe, since there is no part of it in which the workman will not be able to prosecute his education. The difference of language will then be no obstacle. Not only would the sense of fraternity among Western nations be strengthened by such a plan, but great improvement would result esthetically. The languages of Europe would be learnt more thoroughly, and there would be a keener appreciation of works of art, whether musical, pictorial, or architectural; for these can never be properly appreciated but in the country which gave them birth.
