Unrestrained trade in knowledge must banish that trade in merchandise to which states owe their wealth; ruin husbandry, the true mother and nurse of peoples; and destroy our source of soldiery, which springs up in rustic ignorance rather than from the forcing-ground of culture and the sciences. It would fill France with half-taught fellows, minds formed only to _chicane_, men who might ruin families and trouble public peace, but could not be of any service to the state. There would be more people capable of doubts than capable of resolving them; more intelligences fitted to oppose than to defend the truth. Indeed, when I consider the great number who make a profession of teaching, and the crowds of children who are taught, I seem to see an infinite multitude of weaklings and diseased, who, having no other desire than to drink pure water for their healing, are urged by an inordinate thirst to drink all that is offered them, though it is mostly impure and often poisoned, whereby their thirst and their malady are equally aggravated. Two principal evils arise from the great number of colleges established in every district: there are not sufficient worthy teachers to supply them; and many children of little aptitude are compelled by their parents to study. In the result, almost all the pupils leave with but a smattering of learning, some because they have been badly taught, others because they have been incapable of more. The remedy that I propose is this. Let the colleges in all towns which are not of metropolitan rank be reduced to two or three classes, sufficient to raise the young out of gross ignorance, such as is harmful even to those who are destined for military service or for trade. Then, before the children are determined to any special line of life, two are three years will reveal their dispositions and their capacities; and the more promising children, who will then be sent on to the metropolitan colleges, will succeed far better; for they will have minds suited for education and will be placed in the hands of the best teachers. Finally, let care be taken that the colleges shall not all come under the same hands. The universities, on the one hand, the Jesuits on the other, tend towards a monopoly of education. Let their emulation increase their virtues and efficiency; but let neither party be deprived of the instruction of youth; let neither secure a monopoly. _Of the Nobility_ The nobility, which is one of the principal nerves of the state, may contribute much to its consolidation and power, but it has been for some time past greatly depreciated by the large number of officials whom the misfortunes of our age have raised up to its prejudice. It must be supported against the enterprises of people of that kind, whose wealth and pride overwhelmed the nobles, who are rich only in courage.
