The rule and measure of duty is not utility, nor expedience, nor the happiness of the greatest number, nor State convenience, nor fitness, order, and the pulchrum. Conscience is not a long-sighted selfishness, nor a desire to be consistent with oneself; but it is a messenger from Him, who, both in nature and in grace, speaks to us behind a veil, and teaches and rules us by His representatives. Conscience is the aboriginal Vicar of Christ, a prophet in its informations, a monarch in its peremptoriness, a priest in its blessings and anathemas, and, even though the eternal priesthood throughout the Church could cease to be, in it the sacerdotal principle would remain and would have a sway.
Words such as these are idle empty verbiage to the great world of philosophy now. All through my day there has been a resolute warfare, I had almost said conspiracy against the rights of conscience, as I have described it. Literature and science have been embodied in great institutions in order to put it down. Noble buildings have been reared as fortresses against that spiritual, invisible influence which is too subtle for science and too profound for literature. Chairs in Universities have been made the seats of an antagonist tradition. Public writers, day after day, have indoctrinated the minds of innumerable readers with theories subversive of its claims. As in Roman times, and in the middle age, its supremacy was assailed by the arm of physical force, so now the intellect is put in operation to sap the foundations of a power which the sword could not destroy. We are told that conscience is but a twist in primitive and untutored man; that its dictate is an imagination; that the very notion of guiltiness, which that dictate enforces, is simply irrational, for how can there possibly be freedom of will, how can there be consequent responsibility, in that infinite eternal network of cause and effect, in which we helplessly lie? and what retribution have we to fear, when we have had no real choice to do good or evil?
