I am posting here my new translations of the sections on vision, smell and hearing from Avicenna's Shifa.  These translations are from the Latin version published by Brill: Liber de Anima seu Sextus de Naturalibus.

From Part II, I have translated the following sections:

• Chapters 4 and 5, on sound and smell.

From Part III, on vision, I have published the following chapters:

• Chapter 1: On light and luminance
• Chapter 2: That a ray is not a body, and its differences from bodies enumerated
• Chapter 3: On what we must say about color
• Chapter 4: A consideration of other theories on colors and their accidents
