Dear Sir,—I know not what, unless it were the prophet of Tippecanoe, had turned my curiosity to inquiries after the metaphysical science of the Indians, their ecclesiastical establishments, and theological theories; but your letter, written with all the accuracy, perpiscuity, and elegance of your youth and middle age, as it has given me great satisfaction, deserves my best thanks.
It has given me satisfaction, because, while it has furnished me with information where all the knowledge is to be obtained that books afford, it has convinced me that I shall never know much more of the subject than I do now. As I have never aimed at making my collection of books upon this subject, I have none of those you abridged in so concise a manner. Lafitan Adair, and De Bry, were known to me only by name.
The various ingenuity which has been displayed in inventions of hypothesis, to account for the original population of America, and the immensity of learning profusely expended to support them, have appeared to me for a longer time than I can precisely recollect, what the physicians call the Literæ nihil Sanantes. Whether serpents teeth were sown here and sprang up men; whether men and women dropped from the clouds upon this Atlantic Island; whether the Almighty created them here, or whether they emigrated from Europe, are questions of no moment to the present or future happiness of man. Neither agriculture, commerce, manufactures, fisheries, science, literature, taste, religion, morals, nor any other good will be promoted, or any evil averted, by any discoveries that can be made in answer to these questions.
The opinions of the Indians and their usages, as they are represented in your obliging letter of the 11th of June, appear to me to resemble the Platonizing Philo, or the Philonizing Plato, more than the genuine system of Indianism.
The philosophy both of Philo and Plato are at least as absurd. It is indeed less intelligible.
Plato borrowed his doctrines from Oriental and Egyptian philosophers, for he had travelled both in India and Egypt.
The Oriental philosophy, imitated and adopted, in part, if not the whole, by Plato and Philo, was
1. One God the good.
2. The ideas, the thoughts, the reason, the intellect, the logos, the ratio of God.
3. Matter, the universe, the production of the logos, or contemplations of God. This matter was the source of evil.
