1. How can a single teacher instruct a large number of children at the same time? In answer, he maintains that it is not only possible for one teacher to instruct several hundred children (!) at once, but that it is essential for the best interests of both the teacher and the children (!!). The larger the number of pupils, the greater will be the teacher’s interest in his work; and the keener his interest, the greater the enthusiasm of his pupils. In the same way, to the children, the presence of a number of companions will be productive not only of utility, but also of enjoyment, since they will mutually stimulate and assist one another. For children of this age, emulation and rivalry are the best incentives to study. The reader will observe that this scheme of Comenius contemplates some adaptation of the system of pupil teaching, and that it interdicts all efforts at individual instruction. 2. How far is it possible for pupils to be taught from the same book? It is an undisputed fact, says Comenius, that too many facts presented to the mind at the same time distract the attention. It will, therefore, be of great advantage if the pupils be permitted to use no books except those which have been expressly composed for the class in which they are. Such books should contain a complete, thorough, and accurate epitome of all the subjects of instruction. They should give a true representation of the entire universe; should be written simply and clearly—preferably in the form of a dialogue; and should give the pupils sufficient assistance to enable them, if necessary, to pursue their studies without the help of a master. 3. How is it possible for all the pupils in a school to do the same thing at one time? This may be accomplished by having a course of instruction commence at a definite time of each year; and by and by so dividing the course of instruction that each year, each month, each week, each day, each hour may have a definite appointed task for it. 4. How is it possible to teach everything according to one and the same method? That there is only one natural method has already been satisfactorily demonstrated (to the mind of Comenius), and the universal adoption of this natural method will be as great a boon to pupils as a plain and undeviating road is to travellers. 5. How can many things be explained in a few words? The purpose of education is not to fill the mind with a dreary waste of words from books. Rightly says Seneca of instruction: “Its administration should resemble the sowing of seed, in which stress is laid not on the quantity, but on the quality.”
