[200] The passage just quoted in the preceding note continues, “Porro Ptolemaeus dicit ... sed experti sumus multoties hoc non recipi.” See also the following chapter of the Epitome, II, xi.
[201] Epitome, II, xxii, “... et est ratio experimentata haec....”
[202] See III, xii, where, after stating the discordant views of astrologers he says, “Hanc vero postremam rationem experimentis caeteris preponimus.”
[203] Ed. Ludwig Baur, in Beiträge, IV, 2-3, Münster, 1903, pp. 1-144 text; pp. 145-408 “Untersuchung.” Another work by Gundissalinus on the immortality of the soul was published in the same series by G. F. von Hertling, 1897.
Baur unfortunately failed to note the existence of the De divisione philosophiae in two 13th century MSS at the British Museum in the Sloane collection, nor does Scott’s Index catalogue of the Sloane MSS mention Gundissalinus as their author.
Sloane 2946, 13th century, fols. 209-16, “de philosophia ... auctore Isaaco philosopho.” But the Incipit, “Felix prior aetas qui (quae) tot sapientes ...” is that of Gundissalinus’ treatise. The erroneous ascription to Isaac is probably owing to the fact that the treatise just preceding, at fols. 205-208v, is a translation of a medical work by Isaac. This MS is mutilated towards the close so that the leaves containing our text have the upper right hand corner torn off, thus removing nearly one-sixth of the text. The colophon reads, “Explicit hoc opus a domino Gundissalini apud Tholetum editum, sdens (succedens?) de assignanda causa ex qua orte sunt scientie philosophie et ordo eorum et disciplina.” Similarly in Baur’s text the De divisione philosophiae at pp. 1-142 is followed at pp. 142-44 by Alfarabi’s “Epistola de assignanda causa ex qua orte sunt scientie philosophie et ordo earum in disciplina.”
Sloane 2461, late 13th century, fols. 1-38r, contains the De divisione philosophiae under the caption, Compendium scientiarum, without indication of the author. It also is immediately followed at fols. 38v-40r by De unitate, which Baur found in another MS at the close of Gundissalinus’ De divisione philosophiae, and in a third MS before the above mentioned letter of Alfarabi.
