Marco who is Jessica’s husband and the fetus father employs the rationality theory in determining the moral status of the fetus. As per the theory, rationality is observed as a unique character in human beings that allows them to be virtuous and apply reasoning to their actions (Camosy, 2012). As such, Aristotle claimed that all deficiencies of any being that deter them from fulfilling their unique function of a human being should be avoided through the doctrine that virtue is a mean between deficiency and excess. As a result, rationality is outlined as a necessary though not an adequate condition for evaluating a moral status. Likewise, the theory also contends that rationality is perceived in different degrees whereby the rational soul of women and children is not like that of a man since their actions are not ruled by it (Camosy, 2012).
In this prospect, Marco pleaded with the doctor to refrain from telling Jessica the diagnostic results as he feared that she was not in her right state to make a rational decision based on emotions. This is attributed to the fact that Jessica is a woman whose rationality is seen as not fully developed; thus, her actions could not be based on logic in determining the morals status of the fetus. Likewise, Marco decides to support Jessica in whatever resolution she agrees to make but finds it challenging not to view the fetus as an encumbrance. This conforms to the rationality principle of avoiding deficiencies that deter humans from performing their unique function of human beings, thus; the fetus is professed to have no moral status.
