Paracelsus uses the birth of Adam and Eve to help him define the natural foundation of the human body and the divine origin of the soul in the following tracts. As he thinks about the significance of Adam and Eve, Paracelsus expresses trepidation when he begins to envision the seed of human conception as possibly functioning separate from the divine. His unease in categorizing the seeds of conception as entirely part of the natural world stems from his vociferous lament against what he called ‘foolish doctors’ in many of his other tracts on birth. Recalling that he argued against the kind of medical practice that sought to manipulate human conception, his thoughts about the natural world could undermine his claim that he offers a better approach to medicine. When he argues for the soul as a body within the human body this helps him regain his footing. It also facilitates for him a way to understand that the birth of Christ was more significant than other human births. This was a problem he wrestled with in his Mariological tracts where he aimed to understand human birth as different from Christ's. In the Mariological tracts he focused on Mary's body to understand why Christ's birth was more significant than other human births and was unable to clearly delineate the features of human physicality that differed from Christ's. However, thinking about the bodies of Adam and Eve offers him an opportunity to envision divine and natural aspects of human bodies. When he contemplates the limits of God's work in their births, he begins to articulate an idea of the physical body as separate from the soul and spirit. Furthermore, the comparison of all humans to Adam and Eve leads him to recognize physiological differences between men and women. Adam and Eve serve as models for understanding human bodies in a way that contemplating Christ's birth could not. This chapter explores the various (and inconsistent) ways that Paracelsus contemplates the origins of the body and soul in order to demonstrate how reflecting on the figures Adam and Eve helps him clarify his theory of embodiment.
