Living then so long as a witness, though hardly as an actor, in these scenes of intellectual conflict, I am able to bear witness to views of University Education, without authority indeed in themselves, but not without value to a Catholic, and less familiar to him, as I conceive, than they deserve to be. And, while an argument originating in the controversies to which I have referred, may be serviceable at this season to that great cause in which we are here so especially interested, to me personally it will afford satisfaction of a peculiar kind; for, though it has been my lot for many years to take a prominent, sometimes a presumptuous, part in theological discussions, yet the natural turn of my mind carries me off to trains of thought like those which I am now about to open, which, important though they be for Catholic objects, and admitting of a Catholic treatment, are sheltered from the extreme delicacy and peril which attach to disputations directly bearing on the subject-matter of Divine Revelation. 2. 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
