• I argue that joint attention solves the “base problem” as it arises for Schiffer’s and Lewis’s theories of common knowledge. The problem is that an account is needed of the perceptual base of some forms of common knowledge that gets by without itself invoking common knowledge. The paper solves the problem by developing a theory of joint attention as consisting in the exercise of joint know-how involving particular and sometimes distal targets and arguing that certain joint perceivers can always …Read more

    Loneliness is often described as an experience that is about the absence of other people. But loneliness also has an important self-directed aspect: it is oneself one experiences as lonely. I begin by taking it that what the lonely person experiences as absent are not simply other people but rather certain kinds of social relationships with them. Loneliness then involves a disappointed self-relation, a form of estrangement from oneself. I substantiate this view by appeal to psychological model t…Read more

    I put forward an externalist theory of social understanding. On this view, psychological sense making takes place in environments that contain both agent and interpreter. The spatial structure of such environments is social, in the sense that its occupants locate its objects by an exercise in triangulation relative to each of their standpoints. This triangulation is achieved in intersubjective interaction and gives rise to a triadic model of the social mind. This model can then be used to make s…Read more

    The book offers a new treatment of the capacity to perceive, act on, and know about the world together with others. I argue that creatures capable of joint attention stand in a unique perceptual and epistemic relation to their surroundings: they operate in an environment that they, through their communication with their fellow perceivers, help constitute. I show that this relation can be marshaled to address a range of questions about the social aspect of the mind and its perceptual and cognitiv…Read more

    The Psychological Structure of Loneliness
    International Journal of Environmental Research and Public Health 3 (19): 1061. 2022.
    Despite the current surge of interest in loneliness, its health consequences, and possible remedies, the concept itself remains poorly understood. This paper seeks to contribute to a more fully worked out account of what loneliness consists in. It does this by stressing that loneliness always has an experiential component and by introducing a simple psychological structure to analyze the experience. On this basis, it suggests that we can distinguish between three ways of thinking about the pheno…Read more
