Genetics and the biological sciences are the two contemporary scientific fields most readily called to mind in thinking about science and eugenics. Yet the history of another discipline, psychology, is enmeshed more intricately with eugenics than are the histories of either genetics or even the biological sciences more generally. This is true of the history of eugenics in Canada. Moreover, continuities in the roles that psychology plays in how we think about sorts of people and their ability and right to parent make psychology’s eugenic past relevant to reflection on contemporary and ongoing practices and policies.

Philosophical exploration of individualism and externalism in the cognitive sciences most recently has been focused on general evaluations of these two views (Adams & Aizawa 2008, Rupert 2008, Wilson 2004, Clark 2008). Here we return to broaden an earlier phase of the debate between individualists and externalists about cognition, one that considered in detail particular theories, such as those in developmental psychology (Patterson 1991) and the computational theory of vision (Burge 1986, Segal 1989). Music cognition is an area in the cognitive sciences that has received little attention from philosophers, though it has relatively recently been thrown into the externalist spotlight (Cochrane 2008, Kruger 2014, Kersten forthcoming). Given that individualism can be thought of as a kind of paradigm for research on cognition, we provide a brief overview of the field of music cognition and individualistic tendencies within the field (sections 2 and 3) before turning to consider externalist alternatives to individualistic paradigms (section 4-5) and then arguing for a qualified form of externalism about music cognition (section 6).

David Sloan Wilson has recently revived the idea of a group mind as an application of group selectionist thinking to cognition. Central to my discussion of this idea is the distinction between the claim that groups have a psychology and what I call the social manifestation thesis-a thesis about the psychology of individuals. Contemporary work on this topic has confused these two theses. My discussion also points to research questions and issues that Wilson's work raises, as well as their connection to externalist conceptions of the mind familiar since the work of Putnam and Burge

Fodor's thinking on modularity has been influential throughout a range of the areas studying cognition, chiefly as a prod for positive work on modularity and domain-specificity. In _The Mind Doesn't Work That Way_, Fodor has developed the dark message of _The Modularity of Mind_ regarding the limits to modularity and computational analyses. This paper offers a critical assessment of Fodor's scepticism with an eye to highlighting some broader issues in play, including the nature of computation and the role of recent empirical developments in the cognitive sciences in assessing Fodor's position.

Individuals are a prominent part of the biological world. Although biologists and philosophers of biology draw freely on the concept of an individual in articulating both widely accepted and more controversial claims, there has been little explicit work devoted to the biological notion of an individual itself. How should we think about biological individuals? What are the roles that biological individuals play in processes such as natural selection (are genes and groups also units of selection?), speciation (are species individuals?), and organismic development (do genomes code for organisms)? Much of our discussion here will focus on organisms as a central kind of biological individual, and that discussion will raise broader questions about the nature of the biological world, for example, about its complexity, its organization, and its relation to human thought.

The distinction between positive and negative eugenics is perhaps the best-known distinction that has been made between forms that eugenics takes. Roughly, positive eugenics refers to efforts aimed at increasing desirable traits, while negative eugenics refers to efforts aimed at decreasing undesirable traits. Still, it is easy to fall into confusion in drawing and deploying the distinction in particular contexts. Clarity here is important not only historically, but also for appeals to the distinction in contemporary discussions of “new eugenics” or “newgenics”.

Natural Kinds and Conceptual Change is a refreshingly direct book that challenges a range of orthodox views in the philosophy of science (especially biology), the philosophy of language, and metaphysics. Amongst these are the views that species are individuals rather than natural kinds; that scientists discover the essences of natural kinds; that the causal theory of reference has commonly-ascribed implications for realism and analyticity; that there is an unacceptable form of incommensurability entailed by descriptivism about reference; and that there are good grounds, familiar since Quine, for thinking that there is no distinction of significance to be drawn between changes in meaning and changes in theory. LaPorte argues against all of these claims, and if you are curious about just how he does it, then this is a book for you.
