Bacon recognized great individual differences in the mental capacities of children, and he urged that these differences and special tastes be taken into account by the teachers. He says: “The natural bent of the individual minds should be so far encouraged that a student who shall learn all that is required of him may be allowed time in which to pursue a favorite study. And, furthermore, it is worth while to consider, and I think this point has not hitherto received the attention which its importance demands, that there are two distinct modes of training the mind to a free and appropriate use of its faculties. The one begins with the easiest, and so proceeds to the more difficult; the other, at the outset, presses the pupil with the more difficult tasks, and, after he has mastered these, turns him to pleasanter and easier ones: for it is one method to practise swimming with bladders, and another to practise dancing with heavy shoes. It is beyond all estimate how a judicious blending of these two methods will profit both the mental and the bodily powers. And so to select and assign topics of instruction as to adapt them to the individual capabilities of the pupils,—this, too, requires a special experience and judgment. A close observation and an accurate knowledge of the different natures of the pupils are due from teachers to the parents of these pupils, that they may choose an occupation in life for their sons accordingly. And note further, that not only does every one make more rapid progress in those studies to which his nature inclines him, but, again, that a natural disinclination, in whatever direction, may be overcome by the help of special studies. For instance, if a boy has a light, inattentive, inconstant spirit, so that he is easily diverted, and his attention cannot be readily fixed, he will find advantage in the mathematics, in which a demonstration must be commenced anew whenever the thought wanders even for a moment.” These citations will suggest parallels in the aims of the two great reformers. Both sought to introduce the student to nature at first hand. Both aimed to reorganize the sciences into one great body of coördinated knowledge. Both emphasized the value of the inductive method in the development of subjects of study. Bacon said: “A good method will solve all problems. A cripple on the right path will beat a racer on the wrong path.” Said Comenius: “The secret of education lies in method.” Again: “There is no difficulty in learning Latin: what we want is a good method.” _Ratke_
