In defense of dignity: Reflections on the moral function of human dignity

This paper defends human dignity in two ways. First, by confronting the criticism that human dignity does not serve an important function in contemporary moral discourse and that its function can be sufficiently performed by other moral terms. It is argued that this criticism invites a danger of moral reductionism, which impoverishes moral discourse. The authority of moral philosophy to correct widely shared moral intuitions, rooted in experiences of grave injustices and wrongs, is questioned. Secondly, dignity is defended by showing what is needed to uphold it, both in theory and practice. It is argued, and demonstrated through examples, that human dignity as a universal value ascribed to human beings and the virtue of dignified action are intimately related. This is fleshed out in terms of Kant’s analysis of respect in the practical sense and of virtue as a commitment to the value of dignity as a constitutive end of our moral order. It is furthermore argued that theoretical attempts to ground respect for dignity in human capacities lead to a moral impasse. It is necessary to act as if every human being is worthy of respect. This practical approach requires institutions and specified moral obligations that are integral to the democratic ethos and the rule of law, which guarantees the equal status of human beings. This practical task requires that we consistently tease out and act on the implications of these principles rather than seek deeper justification for the equal worth of humans, articulated in the term human dignity.     

In defense of species

In this paper, I address the charge that the category species should be abandoned in biological work. The widespread appeal to species in scientific discourse provides a presumption in favor of the category's usefulness, but a defeasible presumption. Widely acknowledged troubles attend species: these troubles might render the concept unusable by showing that 'species' is equivocal or meaningless or in some similar way fatally flawed. Further, there might be better alternatives to species. I argue that the presumption in favor of species is not defeated on these scores. Troubles attending species, which arise on account of contextual variation attending the use of 'species', do not indicate that the concept is unusable. And alternatives to the use of 'species', which have been proposed in connection with rank-free systematics and in connection with conservation efforts, fail to provide a proper replacement for species.     

In defense of 'niche modeling'

There is a growing awareness of problems with the estimation of the ecological tolerances of species through correlative modeling approaches. These problems have led some investigators to argue for abandoning terms such as 'ecological niche model' and 'environmental niche model' in favor of the ostensibly more value-neutral 'species distribution model', as the models are thought to frequently be poor estimators of the niche. Here, I argue that most applications to which these models are put require the assumption that they do estimate the niche, however imperfectly, and that obscuring this inescapable and potentially flawed assumption in the terminology may only serve to hinder the development of the field.     

In defense of the organism

Thomas Pradeu’s The Limits of the Self provides a precise account of biological identity developed from the central concepts of immunology. Yet the central concepts most relevant to this task (self and nonself) are themselves deemed inadequate, suffering from ambiguity and imprecision. Pradeu seeks to remedy this by proposing a new guiding theory for immunology, the continuity theory. From this, an account of biological identity is provided in terms of uniqueness and individuality, ultimately leading to a defense of the heterogeneous organism as expressing the highest degree of individuality.
