Abstract
Unfortunately for us, it is only the first half-year of his "System in Lectures" that Santayana wished to retain; to wit, the part dealing fully with the "Order of Knowledge"--although there is some overlapping into the "Order of Nature" as is evidenced externally by the list of assigned reading. There is, however, in this mutilated note-book, a "Preface" in which first the use of the general title "Metaphysics" is indicated, and then the complex sub-title, distinguishing the two "orders," is more fully explained. So all together we are hardly at a complete loss as to the themes of the lectures that composed the second half-year.
