The Leonine editors of St. Thomas' commentary on the Physics (Opera Omnia, ed. Leonina, II, Rome, 1884) used the text of Aristotle printed in the Piana edition (1570) but endeavoured to correct it by collation with three good Vatican MSS. (Cod. Vat. Urb. Lat. 206; Vat. Lat. 2071, and 2072). They were doomed to failure because the first two MSS. contain a different Latin translation from the third MS.! On this see: Mansion, A., 'Sur le texte de la version latine médiévale de la Metaphysique et de la Physique d'Aristote dans les éditions des commentaires de saint Thomas d'Aquin', Revue Neoscolastique de Philosophie, 34 (1932), 65-69. Father I. T. Eschmann, 'A Catalogue of St. Thomas's Works', in Gilson, E., The Christian Philosophy of St. Thomas, New York: Random House, 1955, p. 402, also speaks of 'the unreliability of the Latin Aristotelian text' in the Leonine printing.
This point is vigorously made by Franz Pelster, 'Die Uebersetzungen der aristotelischen Metaphysik in den Werken des hl. Thomas von Aquin', Gregorianum, 17 (1936), 394-397.
The Preface (pp. 53-54) to Aristoteles Latinus, Pars Prior, ed. G. Lacombe et al., Romae, 1939, concludes that Moerbeke's revision is not entirely independent from the earlier Greek-Latin version, though it contains significant corrections.

Grabmann, Guglielmo di Moerbeke, pp. 39-48.
Some years earlier, at the beginning of his paraphrase of Aristotle's Physics, Albert said precisely this: 'Nostra intentio est omnes dictas partes [he had been speaking of the physics, metaphysics and mathematics of Aristotle] facere Latinis intelligibiles' (in I Physicorum, Tract. I, cap. 1).
In Grabmann's reconstruction of the career of Moerbeke (G. di Moerbeke, pp. 41-48) William is working at Orvieto (1261-1264), at Viterbo (1265-1268). Many documents (Grabmann, ibid., p. 49) attest to the fact that Moerbeke was Papal Penitentiary at the court of Clement IV (1265-1268) and we know that this was a period in which he turned out many translations. See G. Verbeke's Introduction, pp. LXIII-LXXXI, to Themistius, Commentaire sur le Traité de l'âme d'Aristote, Louvain: Nauwelaerts, 1957, for additional information on this period in William's translating activity.
See above, note 2, p. xvii. I have checked the cue-words in the first book of Roger Bacon's Quaestiones on the Physics; they indicate that in Book I Thomas was using a text very similar to that commented by Bacon before 1247.

The point is also discussed by Paul Mathews, A Study of St. Thomas' Commentary on the Posterior Analytics (St. Louis U. Dissert., 1958), pp. 248-251.
Cf. Fabro, C., 'Tommaso d'Aquino', Enciclopedia Cattolica, XII (Firenze, 1954) col. 254: 'periodo piu agitato nella vita del Santo'.
Cf. Verbeke, Introd., p. XXXIV, in Themistius, Commentaire sur le Traité de l'âme. As Father A. Dondaine suggests (Secretaires de Saint Thomas, Roma: Editori di S. Tommaso, 1956, p. 25) most of St. Thomas' works after about 1259 may have been dictated--but not necessarily under classroom conditions.
This agrees with Grabmann, Die Werke, p. 275; Mansion, 'Theorie arist. du temps', pp. 304-305; and the most recent estimate in Pattin, art. cit.
For further information on the style of the Thomistic commentaries on Aristotle see: M. D. Chenu, Introduction à l'étude de saint Thomas d'Aquin, Paris: Vrin, 1950, pp. 173-190.
The statement, 'in exemplaribus Graecis dicuntur non haberi', indicates that Thomas has not himself checked the Greek but that he is relying on some Greek scholar, such as William of Moerbeke. Modern editions of the Greek text include this passage without comment.

In his Aquinas Lecture (Thomas and the Physics of 1958: A Confrontation, Milwaukee: Marquette U. Press, 1958) Henry Margenau argues that there is much less difference today between Thomism and the latest physics than there was in the nineteenth century. This is true but it is no service to the thought of Aquinas, or of present-day scientists, to ignore their obvious differences.

Einstein, A., and Infeld, L., The Evolution of Physics, New York: Simon and Shuster, 1938, pp. 6-7, are completely baffled by the definition, and so they condemn it as 'intuitive'.

This passage interprets the Latin Aristotle which reads, 'Dicimus enim fieri ex alio alius et ex altero alterum.' St. Thomas interprets the ex alio aliud as referring to substantial change and the ex altero alterum as referring to accidental change. This difference has been indicated in the translation by translating the ex alio aliud 'one thing . . . from another thing' and the ex altero alterum, 'one . . . from another'.

In ancient astronomy the heavens were divided into four quarters or regions which were called exortum, occasum, meridies, and septentriones. (Cf. Aulus Gellius, Noctes Atticae, II, 21, 1-11, and II, 22, 3-16.) Saint Thomas is apparently referring here to this astronomical distinction.

The Latin word 'alteratio' (alteration) has the same stem as the word 'alterum' (other). The argument here is based on this etymology.

In the Oxford English translation of the Physics lines 227 a 7-9 are placed immediately after line 226 b 31. However, in the Latin Aristotle these lines appear in their original place. Hence St. Thomas' commentary on this chapter of the Physics follows the original order of the text.

For 'torch-race' (Oxford English translation, 228 a 28) the Latin Aristotle has 'in diffusione lampadis' (the diffusion of the torch). In this paragraph St. Thomas is suggesting two possible interpretations of this Latin phrase.

The Latin Aristotle for this line reads as follows: '. . . et contrariae ipsorum loci mutationes sunt.' In his commentary on this line St. Thomas suggests two interpretations for the antecedent to the pronoun 'ipsorum'.

In the Oxford English translation of the Physics the last line of Book V is: 'But there would seem to be a sense in which a state of rest and a motion are opposites' (231 a 18). The Latin translation of the Physics at this point adds the following:
'For when something is being moved and is losing something, it seems to still have that which is being lost. Wherefore, if rest is contrary to motion from here to a contrary, then contraries exist together, if to some degree it is at rest and still remains. But universally in regard to that which is moved, it is both here and in that to which it is moved. Because of this, motion, rather than rest, is contrary to motion. Hence, it has now been explained what motion is simply one. And regarding motion and rest it has also been explained how each is one, and which is contrary to which.'
St. Thomas' position is that not only these added lines, but also lines 231 a 5-18, are not included in the authentic text of Aristotle.

N.B.--Lines 243 a 3-248 a 9 (Book VII, Chapters 2 and 3) of the Oxford English translation of the Physics vary considerably from the corresponding section of the Latin translation of the Physics printed with St. Thomas' commentary. To avoid confusion we have included in Appendix A a literal English rendition of this section of the Latin Physics. In Lectures 3, 4, 5 and 6 of Book VII all references to Aristotle's Physics are made to the English text in Appendix A.

Inquantum iterum ex uno geminato plurima perficiuntur.
Sic fiunt res: et nullo modo ipsius est saeculum unum.
Sic autem permutantur, neque simul perficiuntur:
Sic autem semper sunt immobiles secundum circulum.
