54The So-Called Question of Existence in Aristotle, an. Post. 2. 1-2Review of Metaphysics 34 (1). 1980.IN THE first chapter of the second book of the Analytica Posteriora Aristotle offers a fourfold classification of objects of inquiry He refers to each of them by means of a shorthand expression

19Ethics with Aristotle (review)Philosophy and Phenomenological Research 55 (3): 728-731. 1995.The author’s declared goal in this book is to convey “what has registered with [her] as crucial for the understanding of Aristotle’s ethics”. There is no lack of direct philosophical argumentation in this valuable work, but if we had to classify it by its contents, we would be well advised to place it on our shelves among the commentaries on the Nicomachean Ethics.

56On the Ethical Evaluation of Stem Cell Research: Remarks on a Paper by N. KnoepfflerKennedy Institute of Ethics Journal 14 (1): 75-80. 2004.: This response to Nikolaus Knoepffler's paper in the same issue of the Journal agrees that if the arguments supporting the first two of the eight human embryonic stem cell research policy options discussed are unsound, as Knoepffler argues, then it seems natural to move to the increasingly permissive options. If the arguments are sound, however, then the more permissive options should be rejected. It is argued that three of the rejected arguments, taken together, constitute very good reasons to…Read more

25The Foundations of Socratic EthicsPhilosophical Review 105 (2): 233. 1996.Self-interest theories hold that rationality requires one always to choose what is best for oneself. Where these theories differ is in their accounts of what is best for one. Hedonism is a typical self-interest theory, distinguished from other versions by the claim that what is best for one is what gives one the greatest net balance of pleasure over pain. Gómez-Lobo thinks that Socrates is a self-interest theorist: Socrates believes that “a choice is rational if and only if it is a choice of wha…Read more

81Does respect for embryos entail respect for gametes?Theoretical Medicine and Bioethics 25 (3): 199-208. 2004.Respect for human embryos is often defended on the basis of the potentiality argument: embryos deserve respect because they already possess potentially the features that in adults are fully actualized. Opponents of this argument challenge it by claiming that if embryos should be respected because they are potentially adults, then gametes should be respected because they are potentially embryos. This article rejects this reductio ad absurdum argument by showing that there are two different types …Read more

174On potentiality and respect for embryos: A reply to Mary MahowaldTheoretical Medicine and Bioethics 26 (2): 105-110. 2005.In order to understand the nature of human embryos I first distinguish between active and passive potentiality, and then argue that the former is found in human gametes and embryos (even in embryos in vitro that may fail to be implanted) because they all have an indwelling power or capacity to initiate certain changes. Implantation provides necessary conditions for the actualization of that prior, active potentiality. This does not imply that embryos are potential persons that do not deserve the…Read more

10Individuality and Human Beginnings: A Reply to David DeGraziaJournal of Law, Medicine and Ethics 35 (3): 457-462. 2007.In a recent article published in the Journal of Law, Medicine & Ethics, David DeGrazia criticized the two pivotal assumptions that underlie President Bush’s policy on funding stem cell research. Those assumptions are that we originate as single-cell zygotes at the time of conception and that we have full moral status as soon as we originate.In this paper, I would like to concentrate on the first of those assumptions and show in light of recent findings in embryological development that DeGrazia’…Read more

86Inviolability at any ageKennedy Institute of Ethics Journal 17 (4): 311-320. 2007.: This paper starts from three assumptions: that we are essentially human organisms, that we start to exist at conception, and that we retain our identity throughout our lives. The identity claim provides the background to argue that it is irrational for a person to claim that it would be impermissible to kill her now but permissible to have killed her at an earlier age. The notion of "full moral status" as an ascertainable property is questioned and shown to be dependent on previously accepted …Read more

149Sixteen days? A reply to B. Smith and B. Brogaard on the beginning of human individualsJournal of Medicine and Philosophy 31 (2). 2006.When does a human being begin to exist? Barry Smith and Berit Brogaard have argued that it is possible, through a combination of biological fact and philosophical analysis, to provide a definitive answer to this question. In their view, a human individual begins to exist at gastrulation, i. e. at about sixteen days after fertilization. In this paper we argue that even granting Smith and Brogaard's ontological commitments and biological assumptions, the existence of a human being can be shown to …Read more

15Subjetividad y lenguaje en Freud y Lacan: del sujeto del inconsciente al giro pragmático de la filosofíaAnales Del Seminario de Historia de la Filosofía 39 (2): 417-431. 2022.The following article presents an analysis of the conflict that occurs between philosophy and psychoanalysis in both the works of Sigmund Freud and Jacques Lacan; This conflict is conveyed from the alienated condition of the subject that arises from the thesis of the unconscious. The subject deconstructs himself as consciousness and reveals the impossibility of him in the very act in which he presents himself through his saying. In this way, language configures the Freudo-Lacanian idea of the un…Read more
