Rethinking emotion as a natural kind: Correctives from Spinoza and hierarchical homology.

It is commonly claimed that the folk category of emotion does not constitute a natural kind, due to the significant compositional differences between its members, especially basic and complex emotions. Arguably, however, this conclusion stems from the dualistic philosophical anthropology underlying the discussion, which presupposes a metaphysical "split" between mind and body. This is the case irrespective of whether a traditional or biological (homology-based) approach to natural kinds is adopted. Since the origins of this increasingly disputed anthropology can ultimately be traced to Descartes' substance dualism, its adverse effects can likewise be addressed using a contemporary theory of emotion developed from Spinoza, one of Descartes' earliest critics on this issue. Furthermore, a Spinozistic view of emotion accords with the recent shift to a hierarchical approach to homology, which recognises that the evolutionary lineage of complex biological units should be traced via relational qualities rather than physical characteristics. Both the Spinozistic approach to emotion and the hierarchical approach to homology show that the compositional variation in the folk category of emotion does not necessarily preclude it from constituting a natural kind.

Delirium Management: Anything's Possible.

Le délirium est un problème de santé majeur aux conséquences potentiellement graves. Malheureusement, la prise en charge de ce trouble est souvent sous-optimale. Nous considérons que les lacunes dans les soins offerts aux patients avec délirium sont liées aux particularités de cette condition, qui affecte la perception du « soi ¼ de la personne qui en souffre. Cette atteinte entraîne un comportement hors de contrôle chez la personne avec délirium et l'expose à une déshumanisation mécaniste. Une solution consisterait à favoriser une vision élargie du « soi ¼, inspirée de la philosophie et des sciences cognitives récentes, afin d'aider les cliniciens dans la compréhension du comportement pathologique en tant que manifestation de la perturbation de la pensée. Une approche centrée sur l'éthique des soins, intégrant un nouveau cadre pour la relation patient-soignant, est proposée. Considérées dans leur ensemble, les propositions novatrices émises pourraient faciliter l'élaboration d'un cadre de pratiques et de relations plus attentionnées et plus efficaces pour le traitement du délirium.Delirium is a major health care problem with potentially serious consequences. Sub-optimal management is an unfortunate but pervasive hallmark of the disorder. We argue that lapses in the care of delirious patients are related to the peculiarities of delirium as a disorder that affects the "self" of the sufferer. Therefore, corruption of self renders behaviour outside the control of the delirious individual and places the person at risk of mechanistic dehumanisation. A proposed solution is to foster an expanded view of the self, taken from recent philosophy and cognitive science, which would allow the clinician to understand pathological behaviour as indicative of disruption to thought. An ethics of care approach that reframes the patient/carer relationship is proposed. These unique propositions could, together, facilitate the development of a framework of more caring and effective practices and relationships for delirium treatment.
