§ 19. Before Comenius, no one had brought the mind of a philosopher to bear practically on the subject of education. Montaigne and Bacon had advanced principles, leaving others to see to their application. A few able schoolmasters, Ascham, _e.g._, had investigated new methods, but had made success in teaching the test to which they appealed, rather than any abstract principle. Comenius was at once a philosopher who had learnt of Bacon, and a schoolmaster who had earned his livelihood by teaching the rudiments. Dissatisfied with the state of education as he found it, he sought for a better system by an examination of the laws of Nature. Whatever is thus established is indeed on an immovable foundation, and, as Comenius himself says, “not liable to any ruin.” It will hardly be disputed, when broadly stated, that there are laws of Nature which must be obeyed in dealing with the mind, as with the body. No doubt these laws are not so easily established in the first case as in the second, nor can we find them without much “groping” and some mistakes; but whoever in any way assists or even tries to assist in the discovery, deserves our gratitude; and greatly are we indebted to him who first boldly set about the task, and devoted to it years of patient labour. § 20. Comenius has left voluminous Latin writings. Professor Laurie gives us the titles of the books connected with education, and they are in number forty-two: so there must be much repetition and indeed retractation; for Comenius was always learning, and one of his last books was _Ventilabrum Sapientiæ, sive sapienter sua retractandi Ars_—_i.e._, “Wisdom’s Winnowing-machine, or the Art of wisely withdrawing one’s own assertions.” We owe much to Professor Laurie, who has served as a _ventilabrum_ and left us a succinct and clear account of the Reformer’s teaching. I have read little of the writings of Comenius except the German translation of the “Great Didactic,” from which the following is taken. § 21. We live, says Comenius, a threefold life—a vegetative, an animal, and an intellectual or spiritual. Of these, the first is perfect in the womb, the last in heaven. He is happy who comes with healthy body into the world, much more he who goes with healthy spirit out of it. According to the heavenly idea, man should (1) know all things; (2) should be master of all things, and of himself; (3) should refer everything to God. So that within us Nature has implanted the seeds of (1) learning, (2) virtue, and (3) piety. To bring these seeds to maturity is the object of education. All men require education, and God has made children unfit for other employments that they may have leisure to learn.
