    The Beginning of Personhood: A Thomistic Biological Analysis
    (Wiley-Blackwell Publishing Ltd., 2000-04) Eberl, Jason T.
    “When did I, a human person, begin to exist?” In developing an answer to this question, I utilize a Thomistic framework which holds that the human person is a composite of a biological organism and an intellective soul. Eric Olson and Norman Ford both argue that the beginning of an individual human biological organism occurs at the moment when implantation of the zygote in the uterus occurs and the “primitive streak” begins to form. Prior to this point, there does not exist an individual human organism, but a cluster of biological cells which has the potential to split and develop as one or more separate human organisms (identical twinning). Ensoulment (the instantiation of a human intellective soul in biological matter) does not occur until the point of implantation. This conception of the beginning of human personhood has moral implications concerning the status of pre-implantation biological cell clusters. A new understanding of the beginning of human personhood entails a new understanding of the morality of certain medical procedures which have a direct affect on these cell clusters which contain human DNA. Such procedures discussed in this article are embryonic stem cell research, in vitro fertilization, procured abortion, and the use of abortifacient contraceptives.

    Metaphysical and Ethical Perspectives on Creating Animal-Human Chimeras
    (Oxford University Press, 2009-10) Eberl, Jason T.; Ballard, Rebecca A.
    This paper addresses several questions related to the nature, production, and use of animal-human chimeras. At the heart of the issue is whether certain types of animal-human chimeras should be brought into existence, and, if they are, how we should treat such creatures. In our current research environment we recognize a dichotomy between research involving nonhuman animal subjects and research involving human subjects, and the classification of a research protocol into one of these categories will trigger different ethical standards as to the moral permissibility of the research in question. Are animal-human chimeras entitled to the more restrictive and protective ethical standards applied to human research subjects? We elucidate an Aristotelian-Thomistic metaphysical framework in which to argue how such chimeras ought to be defined ontologically. We then examine when the creation of, and experimentation upon, certain types of animal-human chimeras may be morally permissible.

    Peirce on the Symbolical Foundation of Personhood
    (Eidos, 2021-10) De Tienne, André; Philosophy, School of Liberal Arts
    This paper discusses the semiotic and metaphysical framework within which Peirce elaborated a symbolical and dynamical conception of personhood. It exhibits the centrality of Peirce’s early conception of the “unity of consistency” along with its decentering advantages. It describes how this gave rise to a metaphysics of personhood that questions the singularity of individuals. It then conducts a semiotic study of the evolutive process across which something indeterminate evolves into something determinate that increasingly personifies itself following the logic of symbolization, taking into account two major types of indetermination: generality and vagueness. It then considers the kind of teleology at work within personification. It concludes that personhood so conceived is not restricted to only individual human beings, for the process of symbolization at work is not confined to a particular species-specific application.
