Note 24 — LECTURE I. THE EXISTENCE OF UNIVERSAL AND NECESSARY PRINCIPLES.

This lecture on the existence of universal and necessary principles, which was easily comprehended, in 1818, by an auditory to which long discussions had already been presented during the two previous years, appearing here without the support of these preliminaries, will not perhaps be entirely satisfactory to the reader. We beseech him to consult carefully the first volume of the 1st Series of our Course, which contains an abridgment, at least, of the numerous lectures of 1816 and 1817, of which this is a résumé; especially to read in the third, fourth, and fifth volumes of the 1st Series, the developed analyses, in which, under different forms, universal and necessary principles are demonstrated as far as may be, and in the third volume of the 2d Series the lectures devoted to establish against Locke the same principles.
