Excerpt 1

K. fi Manāfiʿ al-aʿḍā’ IX, 4 (Bibliothèque Nationale de France, MS Arabe 2853, fol.156a3-10; John Rylands Library, MS Arabic 809, fol. 155b9-15; National Library of Medicine, MS A 30.1, fol. 134all-17).

If it is like that then what we have explained in the Book on the Opinions of Hippocrates and Plato is correct, namely that the psychic spirit is brought forth by the spirit due to which lifo exists, which rises in the arteries ascending from the heart to the brain and serves as matter and proper material. The matter about which I have written before at the beginning of this book I will repeat here, i.e. that no one can perceive the benefit of any of the partial body parts without knowing the action of the entirety of the body part which is composed of the partial [parts] first. In the Book on the Opinions of Hippocrates and Plato I have brought forward the proof that the rational soul dwells in the brain, that we think with the brain and that it comprises abundant psychic spirit.

K. fi Manāfiʿ al-aʿḍā’ V, 2-3 (Bibliothèque Nationale de France, MS Arabe 2853, fol.79bl6-80a6; John Rylands Library, MS Arabic 809, fol.82all-24; National Library of Medicine, MS A 30.1, fol. 52a3-15).

If there were no prearrangement for widening and emptying this space, the action of what we have described could not be as it should be, and if the fasting intestine stuck to the lower part of the stomach, its coil would cause some significant crowd and constraint in this space. Due to the Agent's foreknowledge of this He did not make coils for the first intestine which meets the stomach, but made it extended and stretched along the spinal column as much as was necessary to widen and empty the space for the bodies which we have mentioned, w h en this ends in the successive intestine, the following part of the intestines winds, bends, folds and has coils.
