If spirit is an abstraction, a conjecture, a chimera; matter is an abstraction, a conjecture, a chimera; for we know as much, or rather as little, about one as the other. We may read Cudworth, Le Clerc, Leibnitz, Berkley, Hume, Bolingbroke and Priestley, and a million other volumes in all ages, and be obliged at last to confess that we have learned nothing. Spirit and matter still remain riddles. Define the terms, however, and the controversy is soon settled. If spirit is an active something, and matter an inactive something, it is certain that one is not the other. We can no more conceive that extension, or solidity, can think, or feel, or see, or hear, or taste, or smell; than we can conceive that perception, memory, imagination, or reason, can remove a mountain, or blow a rock. This enigma has puzzled mankind from the beginning, and probably will to the end. Economy of time requires that we should waste no more in so idle an amusement. In the eleventh discourse of Sir William Jones, before the Asiatic Society, vol. iii., page 229, of his works, we find that Materialists and Immaterialists existed in India, and that they accused each other of atheism, before Berkley, or Priestley, or Dupuis, or Plato, or Pythagoras, were born. Indeed, Newton himself appears to have discovered nothing that was not known to the ancient Indians. He has only furnished more complete demonstrations of the doctrines they taught. Sir John Malcolm agrees with Jones and Dupuis, in the Astrological origin of heathen mythologies. Vain man! mind your own business! Do no wrong;--do all the good you can! Eat your canvas-back ducks! Drink your Burgundy! Sleep your siesta when necessary, and TRUST IN GOD! What a mighty bubble, what a tremendous waterspout, has Napoleon been, according to his life, written by himself! He says he was the creature of the principles and manners of the age; by which, no doubt, he means the age of Reason; the progress of Manilius' Ratio, of Plato's Logos, &c. I believe him. A whirlwind raised him, and a whirlwind blowed him away to St. Helena. He is very confident that the age of Reason is not past, and so am I; but I hope that Reason will never again rashly and hastily create such creatures as him. Liberty, equality, fraternity, and humanity, will never again, I hope, blindly surrender themselves to an unbounded ambition for national conquests, nor implicitly commit themselves to the custody and guardianship of arms and heroes. If they do, they will again end in St. Helena, Inquisitions, Jesuits, and _sacre liques_.
