There are several reasons why I should open the discussion with a reference to the lessons with which past years have supplied me. One reason is this: It would concern me, Gentlemen, were I supposed to have got up my opinions for the occasion. This, indeed, would have been no reflection on me personally, supposing I were persuaded of their truth, when at length addressing myself to the inquiry; but it would have destroyed, of course, the force of my testimony, and deprived such arguments, as I might adduce, of that moral persuasiveness which attends on tried and sustained conviction. It would have made me seem the advocate, rather than the cordial and deliberate maintainer and witness, of the doctrines which I was to support; and, though it might be said to evidence the faith I reposed in the practical judgment of the Church, and the intimate concurrence of my own reason with the course she had authoritatively sanctioned, and the devotion with which I could promptly put myself at her disposal, it would have cast suspicion on the validity of reasonings and conclusions which rested on no independent inquiry, and appealed to no past experience. In that case it might have been plausibly objected by opponents that I was the serviceable expedient of an emergency, and never, after all, could be more than ingenious and adroit in the management of an argument which was not my own, and which I was sure to forget again as readily as I had mastered it. But this is not so. The views to which I have referred have grown into my whole system of thought, and are, as it were, part of myself. Many changes has my mind gone through: here it has known no variation or vacillation of opinion, and though this by itself is no proof of the truth of my principles, it puts a seal upon conviction, and is a justification of earnestness and zeal. Those principles, which I am now to set forth under the sanction of the Catholic Church, were my profession at that early period of my life, when religion was to me more a matter of feeling and experience than of faith. They did but take greater hold upon me, as I was introduced to the records of Christian Antiquity, and approached in sentiment and desire to Catholicism; and my sense of their correctness has been increased with the events of every year since I have been brought within its pale. And here I am brought to a second and more important reason for referring, on this occasion, to the conclusions at which Protestants have arrived on the subject of Liberal Education; and it is as follows: Let it be observed, then, that the principles on which I would conduct the inquiry are attainable, as I have already implied, by the mere experience of life. They do not come simply of theology; they imply no supernatural discernment; they have no special connexion with Revelation; they almost arise out of the nature of the case; they are dictated even by human prudence and wisdom, though a divine illumination be absent, and they are recognized by common sense, even where self-interest is not present to quicken it; and, therefore, though true, and just, and good in themselves, they imply nothing whatever as to the religious profession of those who maintain them. They may be held by Protestants as well as by Catholics; nay, there is reason to anticipate that in certain times and places they will be more thoroughly investigated, and better understood, and held more firmly by Protestants than by ourselves.
