 Consequently I, setting out the truth, which is dear to god and to Aristotle, will here try to do a careful investigation, putting forward the things which Alexander says are the opinions of Plato about the motion of the soul. I do this because of those who deal with his words in a more superficial way and dare to take from them in a way which is hostile to the views of Plato, which is the same as to say hostile to the opinions of Aristotle and to divine truth. (Simplicius, In Cael. 377.20–34, translated by I. Mueller)
