This explains, no doubt, why the attempts to teach the ancient languages _ex usu_, after the manner in which the language of a foreign country is easily learned by residence in that country, had to end in failure. One who learns French in France has persons and actions before his eyes; he easily infers that which concerns him. Such apperception takes place undoubtedly by means of spontaneous ideas with which the foreign language becomes associated. Before long the language itself becomes an apperceiving factor and participates in the process of learning. For the ancient languages, on the contrary, a grammatical working basis is needed first, especially a knowledge of inflectional endings, pronouns, and particles. The blunder should not be made, to be sure, of beginning with a marshalling of the hosts of grammar, as though grammar itself needed no base of operations. Long practice of what is most necessary must precede. But the worst plan would be to start in with cursory reading; in other words, to continue without making sure of anything. Even cursory reading, however, produces good results under one condition; namely, the existence of a lively interest in the contents. 130. When the thoughts of the reader hasten on in advance of the words and get hold of the general sense correctly, the required apperception is performed by means of spontaneous ideas together with the insertion of whatever was not inferred. But this presupposes a very favorable relation of the book to the reader. Hence texts used in the teaching of a language must be chosen with very great care, and their contents explained. Such work should not be slighted in favor of grammar; on the other hand, as much grammar must be given as is necessary. Some of the essentials will have to precede the reading; complementary facts will be presented in connection with the reading; other portions of the grammatical apparatus will be introduced at suitable halting-places. Written exercises belong elsewhere and stand in a different relation to grammar. The interest in an author depends very largely on historical preparation; here we cannot fail to discover connection between philology and the so-called real studies.
