In other works of imagination, those intended for the stage, and in the region of romance, we see the same proofs of the progress of philosophy. Walter Scott's novels are, throughout, the same exhibitions of man, whether acting, speaking or thinking, which a philosopher would take. We are made to see, not by the formality of an instructor, or the impertinence of a cicerone, but by the consummate fidelity and skill of the representation, every motive and passion of the actors laid open to our view, and in strict conformity to what we had often previously observed, though we may not have made it the special subject of reflection. There never was before so much philosophy taught by one writer, or taught in so pleasing a mode, or taught to so many disciples.
Such a gallery of moral pictures could not have been created before the nineteenth century; and though they had been, they would not have met with the same unbounded popularity, but, like Milton's Paradise Lost, would have been in advance of the spirit of the age.
In the drama, the plays of Joanna Baillie, and of Byron, are the most metaphysical of all dramatic productions—so much so, as to make them unsuited either to the tastes or capacities of a promiscuous audience. The tragedies of Voltaire are of a more philosophical character than those of Racine or Corneille, and these again more philosophical than the earlier productions of the French drama.
But it is in history that we most clearly perceive the spirit of the age. Formerly it consisted in little more than a recital of the actions of princes, public or private; and no occurrence in the annals of a nation was deemed worthy of commemoration, except battles and conquests, revolutions and insurrections—with now and then the notice of a plague, famine, earthquake or other general calamity. Now, however, the historian aims to make us acquainted with the progress of society and the arts of civilization; with the advancement or decline of religion, literature, laws, manners, commerce—every thing indeed, which is connected with the happiness or dignity of man; he does this, not only because he deems these subjects more worthy the attention of an enlarged and liberal mind, but also because we can, from a faithful narrative of these events, traced out from their causes, and to their effects, learn the lessons of wisdom—and seeing the approach of evil, be better able to avert or mitigate it. It is in this spirit that all history must now be written, to be approved or even read.
In the study of language, we perceive the same evidences of our intellectual advancement. By arranging the elements of speech according to the physical organs employed in their utterance, great light has been thrown on etymology, and in this way, affinities have been traced, first among languages, and through them among nations apparently unconnected. And as all language consists of signs of our mental operations, the general principles of grammar have been sought in the laws of the mind; while language in turn, has been sometimes successfully invoked to explain those laws; and thus philology and mental philosophy have assisted in elucidating each other.
This branch of philosophy (which treats of our mental faculties) has not indeed made as much progress as many others; for it admits not the discovery of new facts. But neither has this been stationary. Great improvements have been made in analyzing its compound states; in separating its original from its derivative properties; in tracing many seemingly diverse operations to one simple principle. To be convinced of this improvement, we have only to regard the theory of associations as it now is, compared with the slight and vague notice of it by Locke; or advert to the opinions of the same eminent man on the foundation of morals. He maintained that there was no original propensity in mankind to approve one action as virtuous, and another as vicious; and that there was no practical principle which was approved or condemned by all nations. He even denied that parental affection, the strongest feeling in the maternal bosom, was an original feeling. He refers to the inventions of travellers in support of his theory, and was as credulous of the anomalous facts they related, as he was skeptical of innate propensities. Thus he says: "It is familiar among the Mingrelians, a people professing christianity, to bury their children alive without scruple; he asserts that the Caribbees were wont to fat and eat their own children;" and that a people of Peru who followed this practice, used, when by the course of nature they no longer had a prospect of more children to eat, "to kill and eat the mothers."
A more intimate acquaintance with the people of this globe, and juster modes of reasoning, have dissipated these illusions; and if I mistake not, the laws of the mind will, in no distant day, be traced with an accuracy and precision little inferior to those which prevail in most branches of physics.
In the science of political economy too, we see the advance of the light of philosophy. The errors which were the result of general and deep-rooted prejudices, have yielded to the force of reason; and all enlightened men now agree that nothing is so injurious to national prosperity as too much regulation; and that the desire which mankind have to increase their means of enjoyment, operates more unceasingly, and sagaciously, and beneficially, than any schemes of the government, however vigilant, intelligent and free from bias; since governments at best can operate only by general rules, which injure some in benefiting others,—while the sagacity of individuals, with few exceptions, devises the best rules for each particular case.
It was for philosophy also to discover the connection between good government and the national prosperity, and that a community will have the most industry, skill and thrift, where property is best protected—where every one can freely exercise his talents or his capital, and securely enjoy the fruits they have yielded. Philosophy, or unprejudiced reason, if you prefer it, also refuted an error once prevalent, that one country, or one part of a country, was injured by another's welfare; and proved both by reasoning and example, that every accession of wealth or prosperity, experienced by one portion, radiates light and heat to all around it.
If the progress of philosophy, or human reason, has done so much in the moral sciences, it has done yet more in the physical branches of knowledge for the material world—more invites our attention and speculation—is more within the reach of experiment, and the benefits it confers are more direct and obvious. It would be foreign to my purpose, if I were competent to the task, to mark the steps by which man has passed from conjecture to certainly—from rash hypothesis to theories founded on cautious observation and experiment—from inquiries which, if successful, had only gratified curiosity, to discoveries and improvements immediately conducive to the benefits of society. To enable us to appreciate the advance of science, it is sufficient for us to look at what the condition of man now is, compared with what it was.
