I argue that the project of naturalizing intentionality is misconceived. Intentionality should not be considered as a challenge to our naturalistic world-view, but rather as something which gives rise to a logical problem: how to save the principle of indiscernibility of identicals from apparent counterexamples arising from intensional discourse.

Extensionalism, as I understand it here, is the view that physical reality consists exclusively of extensional entities. On this view, intensional entitities must either be eliminated in favor of an ontology of extensional entities, or be reduced to such an ontology, or otherwise be admitted as non-physical. In this paper I argue that extensionalism is a misguided philosophical doctrine. First, I argue that intensional phenomena are not confined to the realm of language and thought. Rather, the ontology of such phenomena (...) is intimately entwined with the ontology of properties. After providing some evidence to the popularity of extensionalism in contemporary analytic philosophy, I investigate the motivating reasons behind it. Considering several explanations, I argue that the main motivating reason is rooted in the identification of matter with extension, an identification which is one of the hallmarks of the mechanistic conception of nature inherited from the founding fathers of our modern scientific outlook. I then argue that such a conception is not only at odds with a robust ontology of properties but is also at odds with our best contemporary physics. Rather than vindicating extensionalism contemporary science undermines the position, and the lesson to be drawn from this surprising fact is that extensionalism needs no longer be espoused as a regulative ideal of naturalistic philosophy. I conclude by showing that the ontological approach to intensional phenomena advocated throughout the paper also gains support from an examination of the historical context within which ‘intension’ was first introduced as a semantic notion.

The Breivik case in Norway has motivated a reassessment of Norwegian insanity law by the Norwegian government. Because Norway since 2002 has utilized a “medical model” for legal insanity—a model according to which the legal excuse of insanity is identified with some medical concept such as psychosis—the Norwegian reexamination of its law is not without interest throughout the world. In this paper, I utilize the Anglo-American experience with different medical models for insanity to assess the current Norwegian law on insanity. (...) I defend a strong version of the medical model against standard criticisms advanced against it in the Anglo-American literature, and venture some suggested improvements in how that model was applied in the Breivik case.

The so-called post-Wittgensteinian Oxford philosophers are often criticized not only for failing to provide for the causal explanation of human behavior and psychological states, but also for failing to recognize that psychological explanations require appeal to sub-personal or molecular processes. Three strategies accommodating this criticism appear in so-called homunculus theories and include: (1) that the sub-systems be assigned intentional or informational content purely heuristically; (2) that the intentional or informational content of molar states be analyzed without remainder in terms of (...) molecular processing; (3) that the entire or salient range of mental or informational molar states be accessible at the molecular level, or vice versa. Option (2) proves to be the most radical and is favored by Dennett. (1) relevantly requires a reduction of the intentional. (3) is illustrated in various ways by the views of Freud, Chomsky, Fodor. (2) is shown to depend on (1) or to be idle; and (3) embraces at least in part an appeal to molar-level explanation. The argument developed attempts to show the sense in which discourse about molar and molecular-level phenomena in the psychological context is fundamentally different from macroscopic and microtheoretical-level discourse about physical phenomena. The conclusion drawn is that neither a molar nor a sub-personal level theory is suitably explanatory in the psychological sense: a psychological theory is committed rather to a set of sub-personal components of such systems, that serve to explain molar phenomena.
