when the ultimate impotence of science is the theme of every cheap philosopher, when constructive philology is reefing its sails, when the judicious grieve at the portentous metaphysical shams of yesterday and smile at those of to-day--such a moment is rather ill chosen for prophesying the extinction of a deep-rooted system of religion because your own studies make it seem to you incredible; especially if you hold a theory of knowledge that regards all opinions as arbitrary postulates, which it may become convenient to abandon at any moment. Modernism is the infiltration into minds that begin by being Catholic and wish to remain so of two contemporary influences: one the rationalistic study of the Bible and of church history, the other modern philosophy, especially in its mystical and idealistic forms. The sensitiveness of the modernists to these two influences is creditable to them as men, however perturbing it may be to them as Catholics; for what makes them adopt the views of rationalistic historians is simply the fact that those views seem, in substance, convincingly true; and what makes them wander into transcendental speculations is the warmth of their souls, needing to express their faith anew, and to follow their inmost inspiration, wherever it may lead them. A scrupulous honesty in admitting the probable facts of history, and a fresh upwelling of mystical experience, these are the motives, creditable to any spiritual man, that have made modernists of so many. But these excellent things appear in the modernists under rather unfortunate circumstances. For the modernists to begin with are Catholics, and usually priests; they are pledged to a fixed creed, touching matters both of history and of philosophy; and it would be a marvel if rationalistic criticism of the Bible and rationalistic church history confirmed that creed on its historical side, or if irresponsible personal speculations, in the manner of Ritschl or of M. Bergson, confirmed its metaphysics.
