Abstract
This essay presents an overview of what Avicenna has to say across his corpus about vegetative faculties and plant life. It begins with a look at more general concerns, including Avicenna’s efforts to enumerate various vegetative faculties according to sound principles, and to not only distinguish them from animal and human faculties, but also explain their integration with those higher faculties. The second half of the essay examines Avicenna’s contributions to more specific issues related to the vegetative life, including zoophytes, reproduction and embryology in his Book of Animals, and the distinction between the concepts of “life” and “soul” in his Book of Plants.
