I have been pointing out how the Fine Arts may prejudice Religion, by laying down the law in cases where they should be subservient. The illustration is analogous rather than strictly proper to my subject, yet I think it is to the point. If then the most loyal and dutiful children of the Church must deny themselves, and do deny themselves, when they would sanctify to a heavenly purpose sciences as sublime and as divine as any which are cultivated by fallen man, it is not wonderful, when we turn to sciences of a different character, of which the object is tangible and material, and the principles belong to the Reason, not to the Imagination, that we should find their disciples, if disinclined to the Catholic Faith, acting the part of opponents to it, and that, as may often happen, even against their will and intention. Many men there are, who, devoted to one particular subject of thought, and making its principles the measure of all things, become enemies to Revealed Religion before they know it, and, only as time proceeds, are aware of their own state of mind. These, if they are writers or lecturers, while in this state of unconscious or semi-conscious unbelief, scatter infidel principles under the garb and colour of Christianity; and this, simply because they have made their own science, whatever it is, Political Economy, or Geology, or Astronomy, to the neglect of Theology, the centre of all truth, and view every part or the chief parts of knowledge as if developed from it, and to be tested and determined by its principles. Others, though conscious to themselves of their anti-christian opinions, have too much good feeling and good taste to obtrude them upon the world. They neither wish to shock people, nor to earn for themselves a confessorship which brings with it no gain. They know the strength of prejudice, and the penalty of innovation; they wish to go through life quietly; they scorn polemics; they shrink, as from a real humiliation, from being mixed up in religious controversy; they are ashamed of the very name. However, they have had occasion at some time to publish on some literary or scientific subject; they have wished to give no offence; but after all, to their great annoyance, they find when they least expect it, or when they have taken considerable pains to avoid it, that they have roused by their publication what they would style the bigoted and bitter hostility of a party. This misfortune is easily conceivable, and has befallen many a man. Before he knows where he is, a cry is raised on all sides of him; and so little does he know what we may call the _lie_ of the land, that his attempts at apology perhaps only make matters worse. In other words, an exclusive line of study has led him, whether he will or no, to run counter to the principles of Religion; which principles he has never made his landmarks, and which, whatever might be their effect upon himself, at least would have warned him against
