[434] Ludwig Baur, Dominicus Gundissalinus, De divisione philosophiae (Baeumker’s Beiträge, Münster, 1903), p. 193 sqq., to which I am indebted for what I have to say in the next few pages.
[435] Migne, Pat. Lat. 64, col. 10 sqq.
[436] These works were written near the middle of the twelfth century. Gundissalinus was Archdeacon of Segovia and drew upon Arab writings.
[437] See L. Baur, Gundissalinus, etc., p. 376 sqq.
[438] The treatise is not printed. Its captions are given by L. Baur in his Gundissalinus, pp. 368-375, from which I have borrowed what I give of them.
[439] Liber de praedicabilibus (tome 1 of Albertus’s works), which in scholastic logic means the five “universals,” genus, species, difference, property, accident, (also called the quinque voces) discussed in Porphyry’s Introduction to the Categories. The Categories themselves are called praedicamenta.
[440] The above gives the arguments of chapters i. and ii. of the work. One notices that Albertus in this exposition of the subject of Porphyry’s treatise, is using the method which Thomas brings to syllogistic perfection in his Summa.
[441] It was printed, more than once, in the late fifteenth century; the most readable edition is that printed at Douai in 1624, in four huge folios.
[442] Boundless as the work appears, neither in mental powers, nor learning, nor in massiveness of achievement, is its author to be compared with Albertus Magnus. The De universo of Rabanus Maurus, Migne 111, col. 9-612, is in its arrangement and method a forerunner of Vincent’s Speculum. Later predecessors were the English Franciscan Bartolomaeus, whose encyclopaedic De proprietatibus rerum was written a little before the middle of the twelfth century (see Felder, Studien in Franciscanerorder, etc., pp. 251-253); and Lambertus Audomarensis (St. Omer) with his Liber floridus, a general digest of knowledge, historical, ecclesiastical, and natural, taken from many writers, an account of which is given in Migne 163, col. 1004 sqq.
[443] Here, of course, we have the hands of Esau, but the voice of Augustine and Orosius!
