Note 29 — LECTURE II. ORIGIN OF UNIVERSAL AND NECESSARY PRINCIPLES.

This theory of spontaneity and of reflection, which in our view is the key to so many difficulties, continually recurs in our works. One may see, vol. i. of the 1st Series, in a programme of the Course of 1817, and in a fragment entitled De la Spontanéité et de la Réflexion; vol. iv. of the same Series, Examination of Reid's Philosophy, passim; vol. v., Examination of Kant's System, lecture 8; 2d Series, vol. i., passim; vol. iii., Lectures on Judgment; 3d Series, Fragments Philosophiques, vol. iv., preface of the first edition, p. 37, etc.; it will be found in different lectures of this volume, among others, in the third, On the value of Universal and Necessary Principles; in the fifth, On Mysticism; and in the eleventh, Primary Data of Common Sense.
