THE KEY OF THE MYSTERIES which balances faith, and it constitutes the whole merit of faith. Nature herself induces us to believe; but the formule of faith are social expressions of the tendencies of faith at a given epoch. It is that which proves the Church to be infallible, evidentially and in fact. God is necessarily the most unknown of all beings because He is only defined by negative experience ; He is all that we are not, He is the infinite opposed to the finite by hypothesis. Faith, and consequently hope and love, are so free that man, far from being able to impose them on others, does not even impose them on himself. “These,” says religion, “are graces.” Now, is it con- ceivable that grace should be subject to demand or exaction; that is to say, could any one wish to force men to a thing which comes freely and without price from heaven? One must not do more than desire it for them. To reason concerning faith is to think irrationally, since the object of faith is outside the universe of reason. If one asks me :—‘‘Is there a God?” I reply, “I believe it.” “But are you sure of it?”—“If I were sure of it, I should not believe it, I should know it.” The formulation of faith is to agree upon the terms of the common hypothesis. Faith begins where science ends. To enlarge the scope of science is apparently to diminish that of faith; but in reality, it is to enlarge it in equal proportion, for it is to amplify its base. One can only define the unknown by its supposed and supposable relations with the known. 15
