Accordingly, such a task ought to be left to the consideration and judgment of the latter, save where such discussions are directly relevant to the topics I will be dwelling upon. I prefer, then, to approach the matters and questions contained here otherwise, namely, archeologically. In this I 3 follow Jose Huertas-Jourda, the editor of the corresponding French vol- 4 ume, in his felicitous terminological choice, although I adopt it here for my purposes in an etymological sense, i. e., as signifying a return to prin- 5 ciples or origins.
