Externalist theories hold that a comprehensive understanding of mental disorder cannot be achieved unless we attend to factors that lie outside of the head: neural explanations alone will not fully capture the complex dependencies that exist between an individual’s psychiatric condition and her social, cultural, and material environment. Here, we firstly offer a taxonomy of ways in which the externalist viewpoint can be understood, and unpack its commitments concerning the nature and physical realization of mental disorder. Secondly, we apply a (...) strongly externalist approach to the case of Autistic Spectrum Disorder, and argue that this condition can be illuminated by appeal to the hypothesis of extended cognition. We conclude by briefly considering the significance this strongly externalist approach may have for psychiatric practice and pedagogy. (shrink)

In this paper I present a new objection to the Aristotelian Naturalism defended by Philippa Foot. I describe this objection as a membership objection because it reveals the fact that AN invites counterexamples when pressed to identify the individuals bound by its normative claims. I present three examples of agents for whom the norms generated by AN are not obviously authoritative: mutants, aliens, and the Great Red Dragon. Those who continue to advocate for Foot's view can give compelling replies to (...) the first two of these examples, but their replies drive the view into an unwelcome result when it faces the last example. I conclude that the concept of being human, on which AN crucially depends, is not as straightforward as Foot's advocates presume. (shrink)

It is now widely accepted that a scientifically credible conception of human nature must reject the folkbiological idea of a fixed, inner essence that makes us human. We argue here that to understand human nature is to understand the plastic process of human development and the diversity it produces. Drawing on the framework of developmental systems theory and the idea of developmental niche construction we argue that human nature is not embodied in only one input to development, such as the (...) genome, and that it should not be confined to universal or typical human characteristics. Both similarities and certain classes of differences are explained by a human developmental system that reaches well out into the 'environment'. We point to a significant overlap between our account and the ‘Life History Trait Cluster’ account of Grant Ramsey, and defend the developmental systems account against the accusation that trying to encompass developmental plasticity and human diversity leads to an unmanageably complex account of human nature.

I argue that Alasdair MacIntyre has important resources to provide in the debate over the moral status of severely disabled people. In contrast, Gregory Poore suggests that MacIntyre’s virtue theory cannot account for our responsibilities to severely disabled people. Given that MacIntyre bases his theory around community membership, this charge is made especially severe in the case of severely disabled strangers. I present an interpretation of MacIntyre that accounts for responsibilities to severely disabled strangers. I then argue that Poore is (...) wrong to conclude that MacIntyre does not include severely disabled people in communities. (shrink)

This paper examines the neo-Aristotelian account of species natures as ‘life-forms’, which we owe to Philippa Foot, Michael Thompson and their defenders. I begin by developing two problems for their view: a problem of underdetermination and a problem generated by psychological work on ‘folk essentialism’. I move on to consider their important transcendental argument, which suggests that claims about life-forms are presupposed by all efforts to describe the organic world. In response, I sketch a neo-Kantian projectivist position, which agrees that (...) life-forms are presupposed in these contexts, while denying that such life-forms are real. This position makes a better sense of the phenomena cited in support of the neo-Aristotelian view, while avoiding the problems raised for that view in the first half of this paper. (shrink)

Werkhoven’s ‘A Dispositional Theory of Health’ is an important and original contribution to debates about the disease concept, which persuasively demonstrates that dispositions must play some role in a full account of what it is to be healthy or ill. Unfortunately, as a theory, it cannot as it stands be correct.I first demonstrate what appears to be a significant, and possibly fatal, flaw; the proliferation of dispositions which Werkhoven’s theory requires makes impossible, at least in the absence of significant further (...) metaphysical work, the comparative numerical judgements on which its account of health and illness are based. I then demonstrate two further problems, concerning the exclusion of ‘technological’ dispositions from those under consideration, and a large class of compensatory biological functions which Werkhoven’s theory seems to have overlooked.

This paper proposes a novel method for identifying the public evaluative standards that contribute to the classification of certain conditions as mental disabilities. Public evaluative standards could contribute to ascertaining disabilities by outlining characteristics whose presence beyond a threshold is fundamentally important for the life of a person and whose absence or reduced occurrence constitutes a disability. Additionally, they can participate in determining disabilities by delineating particularly grave difficulties, impairments, or incapacities. Our method relies on a model of public justification (...) of evaluative standards that is inspired by Gerald Gaus’s theory of public reason. Thus, our approach recommends the justification of evaluative standards through sound deliberative routes from reasons accessible to all persons who participate in the process of justification and the convergence of what is justified in this way to each of them. We deem that disabilities could be caused both by problems in the internal characteristics of a person as well as by unfairness or a lack of hospitality in external circumstances. This is why the method of justification is applied to the assessment of those circumstances as well. If social or environmental circumstances cannot be justified through the convergence of reasons accessible to all persons involved in the process of justification, we have reasons to exclude the presence of a disability and ascertain the presence of inadequate external conditions.
