The three projects that make up this dissertation try to articulate an ontological idea of art; which is to say, they all approach art, or the imagination (as in project two), from the standpoint of a philosophical question concerning the sense of being. The ontological question is elaborated in terms of a theory of the spatial-temporal structure of the aesthetic or sensible realm. This kind of ontology contrasts with a more traditional metaphysical one, where the sense of being is sought within the purely intelligible realm, a realm that transcends the sensible. In projects one and two, the contrast is developed in terms of the Nietzschean/Heideggerian critique of metaphysics, and through the work of Jean-Luc Nancy, who appropriates this critique. In project three, it is developed in terms of Bergson and Deleuze's critique of objective time, or of any attempt to define being and time in terms of what is static and unchanging. Art is central for the ontology at stake here, and the ontology is one of art, because it is a matter of questioning the spatial-temporal being of the sensible, and not the being of the purely intelligible; and because art (as I try to show) is itself essentially concerned with revealing this ontological dimension of the sensible.

Depression during the transition into adulthood is a growing mental health concern, with overwhelming evidence linking the developmental risk for depressive symptoms with maternal depression. In addition, there is a lack of research on the protective role of socioemotional competencies in this context. This study examines independent and joint effects of maternal depression and trait emotional intelligence (TEI) on the longitudinal trajectory of depressive symptoms during emerging adulthood. A series of latent growth models was applied to three biennial cycles of data from a nationally representative sample (N=933) from the Canadian National Longitudinal Survey of Children and Youth. We assessed the trajectory of self-reported depressive symptoms from age 20 to 24 years, as well as whether it was moderated by maternal depression at age 10 to 11 and TEI at age 20, separately by gender. The results indicated that mean levels of depression declined during the emerging adulthood in females, but remained relatively stable in males. Maternal depressive symptoms significantly positively predicted depressive symptoms across the entire emerging adulthood in females, but only at age 20-21 for males. In addition, likelihood of developing depressive symptoms was attenuated by higher global TEI in both females and males, and additionally by higher interpersonal skills in males. Our findings suggest that interventions for depressive symptoms in emerging adulthood should consider development of socioemotional competencies.
