Yet it is to the sense-realists of the earlier half of the seventeenth century that we owe the scientific foundations of educational method, and the only indication of the true line of answer to the complaints of the time. In their hands sense-realism became allied with Protestant theology, and pure humanism disappeared. They were represented first by Wolfgang von Ratich, a native of Holstein, born in 1571. Ratich was a man of considerable learning. The distractions of Europe, and the want of harmony, especially among the churches of the Reformation, led him to consider how a remedy might be found for many existing evils. He thought that the remedy was to be found in an improved school system--improved in respect both of the substance and method of teaching. In 1612, accordingly, he laid before the Diet of the German empire at Frankfort a memorial, in which he promised, "with the help of God, to give instruction for the service and welfare of all Christendom." The torch that fell from Ratich's hand was seized, ere it touched the ground, by John Amos Comenius, who became the head, and still continues the head, of the sense-realistic school. His works have a present and practical, and not merely a historical and speculative, significance. Not only had the general question of education engaged many minds for a century and more before Comenius arose, but the apparently subsidiary, yet all-important, question of method, in special relation to the teaching of the Latin tongue, had occupied the thoughts and pens of many of the leading scholars of Europe. The whole field of what we now call secondary instruction was occupied with the one subject of Latin; Greek, and occasionally Hebrew, having been admitted only in the beginning of the sixteenth century, and then only to a subordinate place. This of necessity. Latin was the one key to universal learning. To give to boys the possession of this key was all that teachers aimed at until their pupils were old enough to study rhetoric and logic. Of these writers on the teaching of Latin, the most eminent were Sturm, Erasmus, Melanchthon, Lubinus, Vossius, Sanctius (the author of the _Minerva_), Ritter, Helvicus, Bodinus, Valentinus Andreæ, and, among Frenchmen, Coecilius Frey. Nor were Ascham and Mulcaster in England the least significant of the critics of method. Comenius was acquainted with almost all previous writers on education, except probably Ascham and Mulcaster, to whom he never alludes. He read everything that he could hear of with a view to find a method, and he does not appear ever to have been desirous to supersede the work of others. If he had found what he wanted, he would, we believe, have promulgated it, and advocated it as a loyal pupil. That he owed much to the previous writers is certain; but the prime characteristic of his work on Latin was his own. Especially does he introduce a new epoch in education, by constructing a
