This fundamental principle of Montesquieu as to the perpetual and ineradicable influence of race, climate, and physical circumstances, in forming national character, and moulding national institutions, is unquestionably the true doctrine on the subject, though probably several generations must pass away, and an incalculable amount of suffering be endured by mankind, before it is generally admitted. Coupled with the cardinal point of the Christian faith, the inherent and _universal_ corruption of the human heart, it forms the only foundation of a salutary or durable government. Decisive proof of this may be found in the fact, that the revolutionary party, all the world over, maintain directly the reverse; viz. that free political institutions, and general education, are all in all; and that, if established, the native virtue of the human heart affords a sufficient guarantee for general happiness. Montesquieu's principles lead to the conclusion that all reform and amelioration of existing institutions, to be either durable or beneficial, must be moulded on the old precedents, and deviate as little as may be, and that only from obvious necessity or expedience, from them. They utterly repudiate all transplantation of constitutions, or forcing upon one people the institutions or privileges of another. They point to experience as the great and only sure guide in social or political change, and for the obvious reason, that it alone can tell what has been found to be suitable to the circumstances, and adapted to the character and wants, of the nation among whom it has taken place. It is not that our ancestors were in the least wiser than we are; doubtless they did many foolish things, as we do. It is that time has consigned their foolish things, whether laws or measures, to the grave; and nothing has descended to our time but those institutions which have been found to be beneficial in their tendency. The portions of our present legislation which are suitable to the country, will in like manner descend to posterity, and the folly and absurdity will in a few generations be heard of no more. It has been already remarked, that the _Grandeur et Decadence des Romains_ is a more complete, and in some respects profound work, than the _Esprit des Loix_. A few quotations will justify, it is thought, this high eulogium--
