The objects of a genuine philosophy, are the discovery and promulgation of the truths which emanate from a knowledge of the laws of nature, in relation to the material world, and the inseparable influence of those truths, consequent on an acquaintance with them, in giving a right direction to the moral faculty of man. The intimate connexion subsisting between natural and moral science, is indubitable; and it is equally certain, that the accordant order, fitness and rectitude, which unite into one glorious plan of wisdom, goodness and power, all portions of creation, intellectual and sensitive as well as material, must rest on the same unerring principles. The infinite variety and boundless extent of nature’s works constitute a sublime system; manifesting a correspondent perfection in the design, and all-bountiful dispensation of good in its purposes.[23] The Almighty First Cause has founded this system on immutable principles; wherein _truth_, in relation to the moral world, may be considered as its basis,—as _fitness_ is, when applied to the constitution of the natural world. These are, respectively, the correlatives of the one and the other: and the unity of design apparent in the whole system, plainly indicates the connexion that subsists, in the nature of things, between moral virtue, which is the result of a right perception of truth, and the fitness and order, to which all the operations of the material universe conform.[24]—Towards an investigation of _these_ things, the researches of the great American philosopher were eagerly directed: such were the objects of his unwearied pursuit; and such were the views entertained by him, of the utility and importance of those sublime branches of knowledge, which he cultivated so ardently and successfully.[25] Footnote 23: It is observed by an eminent philosopher of the present day, that “The more the phænomena of the universe are studied, the more distinctly their connexion appears, the more simple their causes, the more magnificent their design, and the more wonderful the wisdom and power of their Author.” (See _Elements of Chymical Philosophy_, by sir Humphrey Davy, LLD. Sec. R. S.) ----- Footnote 24: On looking into Maclaurin’s Account of Sir Isaac Newton’s Philosophical Discoveries, since penning the above, the writer of these Memoirs was much gratified by the perusal of the following passage, in the last chapter of that valuable work; wherein its author treats “Of the Supreme Author and Governor of the Universe, the True and Living God.” The writer is induced to add it in a note, to his own reflections on the same subject, such as he has ventured to offer them in the text; presuming that the authority of so eminent a philosopher as Mr. Maclaurin will give weight to what he has himself advanced; so far, at least, as there may appear to be some coincidence of sentiment on the subject.
