And more than this, thanks to the co-ordination of lessons well classified, there is, for each course of lectures, the means for arriving at full details in all particulars; the young students can talk amongst themselves and learn from each other, the student of moral science from the student of the natural sciences, the latter from the student of the chemical or physical sciences, and another from the student of the mathematical sciences. Bearing still better fruit, the student, in each of these four circumscriptions, derives information from his co-disciples lodged right and left in the nearest compartments, the jurist from the historian, from the economist, from the philologist, and reciprocally, in such a way as to profit by their impressions and suggestions, and enable them to profit by his. He must have no other object in view for three years, no rank to obtain, no examination to undergo, no competition for which to make preparations, no outward pressure, no collateral preoccupation, no positive, urgent and personal interest to interfere with, turn aside or stifle pure curiosity. He pays something out of his own pocket for each course of lectures he attends; for this reason, he makes the best choice he can, follows it up to the end, takes notes, and comes there, not to seek phrases and distraction, but actualities and instruction, and get full value for his money. It is assumed that knowledge is an object of exchange, foodstuffs stockpiled and delivered by the masters; the student who takes delivery is concerned that it is of superior quality, genuine and nutritious; the masters, undoubtedly, through amour-propre and conscience, try to furnish it this; but it is up to the student himself to fetch it, just what he wants, in this particular storehouse rather than in others, from this or that lecture-stand, official or not. To impart and to acquire knowledge for itself and for it alone, without subordinating this end to another distinct and predominant end, to direct minds towards this object and in this way, under the promptings and restraints of supply and demand, to open up the largest field and the freest career to the faculties, to labor, to the preferences of the thinking individual, master or disciple,--such is (or ought to be) the spirit of the institution. And, evidently, in order that it may be effective according to this spirit, it needs an independent, appropriate body, that is to say, autonomous, sheltered against the interference of the State, of the Church, of the commune, of the province, and of all general or local powers, provided with rules and regulations, made a legal, civil personage, with the right to buy, sell and contract obligations, in short proprietorship.
