which you may choose. It is only in the minor details that there are differences. So too in the case of plants, the development of one plant from its seed, the planting and the growth of a single tree, serve as illustrations of the way in which all the others, without exception, develope. One leaf on a tree resembles all the others, and in this respect does not change from year to year.
47. Deviation.—Differences of method, therefore, confuse the young, and make their studies distasteful to them, since not only do different teachers use different systems, but even individual teachers vary their method. For example, languages are taught in one way, dialectic in another, though both might be brought under the same method, in accordance with the harmony of the universe, and the universal and intimate relations that exist between objects and words.
48. Rectification.—Henceforth, therefore
(i) The same method of instruction must be used for all the sciences, the same for all the arts, and the same for all languages.
(ii) In each school the same arrangement and treatment should be adopted for all studies.
(iii) The class-books for each subject should, as far as is possible, be of the same edition.
In this way difficulties will be avoided and progress will be made easy.
