Guided by the light of reason, we comprehend under the name of virtue those habitual dispositions of the heart which tend to the happiness and the real advantage of those with whom we associate, and by the exercise of which our fellow-creatures are induced to feel a reciprocal interest in our welfare. Under the Christian system the name of virtues is bestowed upon dispositions which it is impossible to possess without supernatural grace; and which, when possessed, are useless, if not injurious, both to ourselves and others. The morality of Christians is, in good truth, the morality of another world. Like the philosopher of antiquity, they keep their eyes fixed upon the stars till they fall into a well, unperceived, at their feet. The only object which their scheme of morals proposes to itself is, to disgust their minds with the things of this world, in order that they may place their entire affections upon things above, of which they have no knowledge whatever; their happiness here below forms no part of their consideration; this life, in the view of a Christian, is nothing but a pilgrimage, leading to another existence, infinitely more interesting to his hopes, because infinitely beyond the reach of his understanding. Besides, before we can deserve to be happy in the world which we do not know, we are informed that we must be miserable in the world which we do know; and, above all things, in order to secure to ourselves happiness hereafter, it is especially necessary that we altogether resign the use of our own reason; that is to say, we must seal up our eyes in utter darkness, and surrender ourselves to the guidance of our priests. These are the principles upon which the fabric of Christian morals is evidently constructed.
