In addressing bioethical issues at the beginning of human life, such as abortion, in vitro fertilization, and embryonic stem cell research, one primary concern regards establishing when a developing human embryo or fetus can be considered a person. Thomas Aquinas argues that an embryo or fetus is not a human person until its body is informed by a rational soul. Aquinas's explicit account of human embryogenesis has been generally rejected by contemporary scholars due to its dependence upon medieval biological data, (...) which has been far surpassed by current scientific research. A number of scholars, however, have attempted to combine Aquinas's basic metaphysical account of human nature with current embryological data to develop a contemporary Thomistic account of a human person's beginning. In this article, I discuss two recent interpretations in which it is argued that a human person does not begin to exist until a fetus has developed a functioning cerebral cortex. (shrink)

I approach the subject of human enhancement—whether by genetic, pharmacological, or technological means—from the perspective of Thomistic/Aristotelian philosophical anthropology, natural law theory, and virtue ethics. Far from advocating a restricted or monolithic conception of “human nature” from this perspective, I outline a set of broadly-construed, fundamental features of the nature of human persons that coheres with a variety of historical and contemporary philosophical viewpoints. These features include self-conscious awareness, capacity for intellective thought, volitional autonomy, desire for pleasurable experiences, and the (...) necessity of healthy biological functioning. On this basis, I contend that there may be legitimate forms of human enhancement for specific purposes related to the physical, cognitive, and emotive dimensions of human existence. However, wider philosophical considerations call into question whether societal attitudes towards enhancement and the differences that may emerge between those who are enhanced versus the unenhanced may raise insurmountable questions of justice, as well as a loss of virtues associated with what Alasdair MacIntyre refers to as our “acknowledged dependency.” This presentation will navigate towards conclusions differentiating principled from practical objections to specific forms of, and means towards achieving, enhancement of certain human capacities. While critical of some forms of human enhancement, I nevertheless argue that other forms of enhancement are, in principle, morally permissible—and for which any practical concerns may be surmountable—insofar as they positively support human flourishing according to our nature as living, sentient, social, and rational animals.

One of Thomas Aquinas’s primary philosophical concerns is to provide an account of the nature of a human soul. He bases his account on Aristotle’s De anima, wherein Aristotle gives an account of “soul” (psuchē) as divided into three distinct types: vegetative, sensitive, and intellective. Aristotle defines an intellective soul as proper to human beings and the only type of soul that may potentially exist separated from a material body. Aquinas argues that an intellective soul is indeed separable from its (...) body and conceives of it as essentially, or unqualifiedly (simpliciter), immortal and separable from its body, and relatively (secundum quid) mortal and conjoined to its body. Pietro Pomponazzi (1462-1525), a Renaissance philosopher concerned with ridding neo-Aristotelianism of Platonic or Averroistic influences, criticizes Aquinas’s account as not being properly Aristotelian and having been influenced by Platonism. In this paper, I will present summaries of Aquinas’s arguments concerning an intellective soul’s essential immortality, as well as Pomponazzi’s criticisms of Aquinas’s position. I then propose ways in which Aquinas may respond to these criticisms. (shrink)
