As defined by Jesuit authors, the education of youth means the gratuitous teaching of Letters and Science, from almost the first beginnings of Grammar up to the culminating science of Sacred Theology, and that for boys and students of every kind, in schools open to all.[21] Evidently these university men, who were engaged in drawing up the Institute, considered that, if the greatest Professor's talents are well spent in the exposition of the gravest doctrines in Theology, Philosophy, and Science, neither he, nor any one else, is too great to be a schoolmaster, a tutor, and a father, to the boy passing from childhood on to the state of manhood,--that boyhood which, as Clement of Alexandria says, furnishes the very milk of age, and from which the constitution of the man receives its temper and complexion. It is requisite here to observe, that there was no such thing in existence, as State Education. Two reasons may briefly be mentioned for this, one of them intrinsic to the question, the other an historical fact. The intrinsic and essential reason was the sacred character of education, as being an original function, belonging to the primary relations of parents and child. States, or organized commonwealths, come only in the third or fourth degree of human society. It was much later, in that short interval between the extinction of the Society of Jesus and the outburst of the French Revolution, that new theories came to be proclaimed, as La Chalotais did openly proclaim them, of a bald and blank deism in social life, and therefore of secularizing education. Between deism and secularization the connection was reasonable. For, if the rights of God went by the board, there was no reason why the rights of parents and children should remain. All alike, the persons and "souls of men,"[22] fell back into the condition in which Christianity had found them; they became chattels of the state, mannikins of a bureau in peace, "food for powder" in war. The other reason was an historical fact. For all the purposes of charity, mercy, and philanthropy, there were powers in existence, as part of the normal religious life of general Christian society. They were the same powers that had made Christendom, and had carried it on so far as the Christian world, the same to which we owe the civilization of to-day. More than that. As there is not a single work of charity or mercy, say St. Thomas Aquinas, which may not be made the object of an institution, religious men or women devoting their lives as a service to God, in a special service towards their neighbors; so, in point of fact, there were very few such objects which had not originated some service of religious self-consecration in their behalf.
