When I collected these moral sketches, which were written at different times and under varying circumstances, I did not think that I needed to add anything to them. A recent event, however, has determined me, in now publishing them, to say a few words more. What is after all, speaking religiously, the great question, the most important question which at present occupies the minds of men? It is the question in debate between those who acknowledge and those who deny a supernatural, certain, and sovereign order of things, although inscrutable to human reason. The question in dispute, to call things by their right names, between supernaturalism and naturalism. On the one side, unbelievers, pantheists, pure rationalists, and sceptics of all kinds. On the other, Christians. I shall not discuss the matter; I shall lay aside every personal question, every controverted point, every argument. Controversy opens the abyss which it pretends to fill, for it adds the obstinacy of self-love to differences of opinion. To overcome objections raised by honourable and sincere men gives me but little pleasure. I have a higher desire. I aspire to unite myself with them in the truth. Two ideas fill my mind, and predominate on this subject. I wish to set them forth in pure and bright light. If I succeed, if I can transfuse them into other minds, they will do their own work, and render unnecessary the controversy from which I abstain. It would not be worth while to live if we gathered from a long life, no other fruit than a little experience and prudence in the affairs of this world, against the moment of leaving it. The prospect of human affairs, and the inward trials of the soul, afford brighter gleams, which spread themselves over the mysteries of nature and the destiny of man, and of this universe in the midst of which man is placed. I have received from practical life, deeper insight into these formidable questions, than meditation and science have ever given me.
