Judging by our present practice, it would seem impossible to include such a mass of important scientific studies, as are here proposed, in three hundred and sixty lectures. But the length to which courses of lectures on any subject extend at present, is owing partly to the special or professional object with which the course is given, and still more to the discursive and unphilosophical spirit of most of the teachers, consequent on the miserable manner in which our scientific system is organized. Such a regeneration of scientific studies as Positivism proposes, will animate them with a social spirit, and thus give them a larger and more comprehensive tendency. Teachers will become more practised in the art of condensing, and their lectures will be far more substantial. They will not indeed be a substitute for voluntary effort, on which all the real value of teaching depends. Their aim will be rather to direct such effort. A striking example, which is not so well remembered as it should be, will help to explain my meaning. At the first opening of the Polytechnic School, courses of lectures were given, very appropriately named _Revolutionary Courses_, which concentrated the teaching of three years into three months. What was in that case an extraordinary anomaly, due to republican enthusiasm, may become the normal state when a moral power arises not inferior in energy, and yet based upon a consistent intellectual synthesis, of which our great predecessors of the Revolution could have no conception. Little attention has hitherto been given to the didactic value of Feeling. Since the close of the Middle Ages, the heart has been neglected in proportion as the mind has been cultivated. But it is the characteristic principle of Positivism, a principle as fertile in intellectual as in moral results, that the Intellect, whether we look at its natural or at its normal position, is subordinate to Social Feeling. Throughout this course of popular education, parents and masters will seize every suitable occasion for calling Social Feeling into play; and the most abstruse subjects will often be vivified by its influence. The office of the mind is to strengthen and to cultivate the heart; the heart again should animate and direct the mental powers. This mutual influence of general views and generous feelings will have greater effect upon scientific study, from the esthetic culture previously given, in which such habits of mind will have been formed, as will give grace and beauty to the whole life.
