The experience of one’s body as one’s own is normally referred to as one’s “bodily sense of ownership” (BSO). Despite its centrality and importance in our lives, BSO is highly elusive and complex. Different psychopathologies demonstrate that a BSO is unnecessary and that it is possible to develop a limited BSO that extends beyond the borders of one’s biological body. Therefore, it is worth asking: what grounds one’s BSO? The purpose of this paper is to sketch a preliminary answer to (...) the ‘grounding question.’ Thus, I begin by briefly presenting some contemporary competing hypotheses concerning the ‘grounding question’ and explain why they seem unsatisfying. Second, I discuss the “dual-aspect” of bodily awareness, which is manifest in every normal tactile experience and consists in a subject-object structure of awareness. I then argue that the “dual-aspect” of bodily awareness has the potential of explaining BSO and can, therefore, be considered its grounds. Taking the “dual-aspect” of bodily awareness as the grounds of BSO manages to escape difficulties faced by contemporary hypotheses concerning BSO, fulfills certain necessary demands upon any account of BSO, and explains relevant empirical findings and psychopathologies. Consequently, I argue that it is a hypothesis worth pursuing. (shrink)
