It is impossible not to agree with Tocco's verdict, that "However fine the analysis employed in distinguishing the subtlest shades of concepts, however great the number of elevated philosophical thoughts scattered throughout, expounded with vigour and felicity of imagery, the tractate as a whole has little value, just as the _ars inventiva_ itself has little--more fit to blunt than to sharpen the inventive powers."[152] One gladly re-echoes Bruno's words at the close: "_Itaque gratias deo agentes, Artem Inventivam per triginta statuas perfecimus._" 4. _Animadversiones circa Lampaaem Lullianam_ (State Edition, vol. ii. pt. 2).--From the Augustan MSS., dated 13th March 1587. Notes dictated in Wittenberg, on the Lullian art as a universal instrument for the discovery of truth. 5. _Libri Physicorum Aristotelis, a clariss. Dn. D. Jordano Bruno Nolano explanati._--From two codices in the Erlangen Library, the second of which is in the hand of Besler, and was written, presumably, at Helmstadt. The earlier MS. in a German handwriting points to the commentaries having been dictated by Bruno during his stay at Wittenberg.[153] The books of Aristotle treated are the five books of the _Physica_, the _De generatione et corruptione_, the _Meteorologica_, Book IV. There is an introduction on the methods of the sciences, and other matters, by Bruno himself; the remainder follows closely the text of Aristotle, except in the fourth and fifth books, where Bruno is much less exact. 6. _De Magia_, et _Theses de Magia_.--The MS. of this work is in the Erlangen Codex, by Besler, and also in the Moscow (Noroff) collection, by the same hand; the former is a copy of the latter, which was dictated by Bruno in the early part of 1590 at Helmstadt. It deals with one of the three divisions of Magic, viz. Natural or Physical Magic (the others being Divine, Metaphysical or Supernatural, and Mathematical--that of symbols, numbers, etc.). Physical magic is shown to be a natural consequence, first, of the fact that the same soul, the soul of the world, is in all things, of which the individual finite soul of each thing is a temporary mode or phase; hence all things are linked one with another, through their spiritual identity, in a bond of sympathy; secondly, of the hierarchy of beings--the principle that all finite things are emanations, in increasing degree of imperfection, from the Divine. The Theses represent a summary of the _De Magia_, and in the latter the headings of the former are referred to throughout, except in two episodes or excursus not strictly connected with natural magic (on spirit-charms and spirit-analogies): the work is referred to in the _De Minimo_, i. 3. 210 (_re_ the magical influences of bodies newly dead; "the soul everywhere recognises the matter of its own body, as we have shown in the book on physical magic").
