My objective in this essay is two part. Firstly I aim to produce a well-rounded account of the differing approaches to defining personhood, assess their shortcomings and highlight the relationship between personhood and rights. The second part of the essay will be an application of this notion of personhood and the subsequent theory of rights to the sphere of medical ethics, using abortion to demonstrate the important role the notion of personhood plays in medical ethical issues as well as highlighting its limitations.
FIRST I will establish the context of personhood by assessing first the Religious approaches to personhood. Next the Philosophical approach, using the philosophies of Aquinas, Descartes and Locke on personhood. And last the approach of science. All will be viewed in the context of history and how definitions change across history and across culture.
Secondly I will emphasise the undeniable link between concepts of Personhood and the effects it has on human rights. And use Peter Singer to demonstrate issues with a hierarchy of rights.
Lastly I will apply notions of personhood, and the subsequent theory of rights, to the abortion debate in order to demonstrate the impact of personhood in medical ethics. I will then use the works of Judith Thompson and discussions on social influences to highlight the extent of the role that personhood actually plays in medical ethical issues.
