But this freedom is based on laws,--two of which cannot be too distinctly or too often enunciated. A law which should govern the admission of pupils is this, that before they win this privilege they must have been matured by the long, preparatory discipline of superior teachers, and by the systematic, laborious, and persistent pursuit of fundamental knowledge; and a second law, which should govern the work of professors, is this, that with unselfish devotion to the discovery and advancement of truth and righteousness, they renounce all other preferment, so that, like the greatest of all teachers, they may promote the good of mankind. I see no advantage in our attempting to maintain the traditional four-year class-system of the American colleges. It has never existed in the University of Virginia; it is modified, though not nominally given up at Harvard; it is not an important characteristic of Michigan and Cornell; it is not known in the English, French or German universities. It is a collegiate rather than a university method. If parents or students desire us to mark out prescribed courses, either classical or scientific, lasting four years, it will be easy to do so. But I apprehend that many students will come to us excellent in some branches of a liberal education and deficient in others--good perhaps in Greek, Latin and mathematics; deficient in chemistry, physics, zoology, history, political economy, and other progressive sciences. I would give to such candidates on examination, credit for their attainments, and assign them in each study the place for which they are fitted. A proficient in Plato may be a tyro in Euclid. Moreover, I would make attainments rather than time the condition of promotion; and I would encourage every scholar to go forward rapidly or go forward slowly, according to the fleetness of his foot and his freedom from impediment. In other words, I would have our University seek the good of individuals rather than of classes. The sphere of a university is sometimes restricted by its walls or is limited to those who are enrolled on its lists. There are three particulars in which we shall aim at extramural influence: first, as an examining body, ready to examine and confer degrees or other academic honors on those who are trained elsewhere; next, as a teaching body, by opening to educated persons (whether enrolled as students or not) such lectures as they may wish to attend, under certain restrictions--on the plan of the lectures in the high seminaries of Paris; and, finally, as in some degree at least a publishing body, by encouraging professors and lecturers to give to the world in print the results of their researches. What are we aiming at?
