I want to know the answer to the following question:
How many years did it take for Ibn Sina's Book of Healing to be available in Latin?
All the background I'm provided with is that "Avicenna's psychology and theory of knowledge influenced William of Auvergne, Bishop of Paris and Albertus Magnus, while his metaphysics had an impact on the thought of Thomas Aquinas.". Is that enough to answer the question?
Answer: no
