Having a self means being able think of myself under a certain profile that that is me: that is who I am, that is how I am. But if I raise the question as to who or how I am, there are three salient profiles in which I can cast myself, three selves with which we can identify. I can see myself just as an agent identified over time by the linkages between my experiences, my attitudes and my actions. I (...) can see myself as the persona that I invite others to rely on and that, if sincere, I internalize. And I can see myself as the figure I cut in other people's eyes, whether or not I welcome that image. Such ambiguities help explain the complexity in philosophical discussion of the self as well as the conflict in everyday exhortations to be ourselves and know ourselves, yet also to forget ourselves and lose ourselves.

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile for (...) that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)
