The author of the life of Hamilton confidently pronounces what occurred on the appointment of Washington as Commander-in-chief of the Revolutionary army, to be the true source of the party divisions that have so long and so extensively prevailed in this country. President John Quincy Adams, in his Inaugural Address, attributes them to the conflicting prejudices and preferences of the people for and against Great Britain and France at the commencement of the present government, and the discontinuance of them to the effects produced by the excesses of the French Revolution. Matthew L. Davis,--a man of much note and cleverness, who commenced his career an active member of the old Republican party, became the especial champion of Colonel Burr, and, soon seceding from the party to which he was at first attached, spent the remainder of his life in opposition to it,--in his life of Aaron Burr, attributes the origin of our two great political parties to the proceedings of the Federal Constitutional Convention and of the State Conventions which passed upon the question of ratification. These various versions of the matter I shall hereafter notice, contenting myself, for the present, with the remark that party divisions which have extended to every corner of a country as large as our own, and have endured so long, could not spring from slight or even limited causes. No differences in the views of men on isolated questions temporary in their nature, could, it seems to me, have produced such results. Questions of such a character are either finally settled, with more or less satisfaction, or in time lose their interest, notwithstanding momentary excitement, and the temporary organizations springing from them give place in turn to others equally short-lived. But when men are brought under one government who differ radically in opinion as to its proper form, as to the uses for which governments should be established, as to the spirit in which they should be administered, as to the best way in which the happiness of those who are subject to them can be promoted, no less than in regard to the capacity of the people for self-government, we may well look for party divisions and political organizations of a deeper foundation and a more enduring existence.
