In recent years I work on four projects; the first two are empirical and the others are transcendental.
1) Tactile Field
P. F. Strawson (1959) famously argues that though there is a clear sense of the visual field, there is no such analogous sensory field in touch. Brian O'Shaughnessy (1989) and M. G. F. Martin (1992) follow his lead. They emphasise the fact that the spatiality of touch is derived from proprioception, kinesthesia, temporal perception, and vision. With Patrick Haggard and colleagues, I have been attempting to meet this significant challenge. We conduct experiments showing that there is some basic spatiality of touch that is not derived from other modalities (F. Fardo, B. Beck, T. Cheng, and P. Haggard, in preparation). This line of research has rich implications about tactile change blindness, the Molyneux’s Question, peripersonal space, and sense modality individuation.

2) Visual Vagueness
Christopher Peacocke (1986, 1989) introduces the notion of “matching profile” to model analogue representational content, but this approach has since then been forgotten. I seek to invoke it to model conscious phenomenology, emphasising its capacity to capture phenomenal imprecision and overflow. The basic idea is that attention modulates the ranges of matching profiles. I further connect this idea to vagueness, in particular supervaluationism. This is to be distinguished from the indeterminacy view championed by James Stazicker (2011). This line of research has rich implications about the (putative) Bayesian nature of perception, predictive coding, peripheral vision and crowding, (post-) perceptual confidence, multisensory integration, and the perception/cognition divide.

3) Spatial Apperception
Following Quassim Cassam (1997), I argue for a version of "epistemological objectivism": non-linguistic creatures with engaged object cognition must be able to be acquainted with their bodily selves qua subject as physical objects in an objective world. This amounts to a kind of spatial apperception. These are full of jargon, which takes the entire dissertation to unpack. My primary interlocutor here is John Campbell (1994 and beyond). This line of research has rich implications about pre-linguistic objectivity, objective experience, and the self. The conceptual issues in this area are especially thorny from my point of view, so those in preparation pieces will take many years to appear.

4) Immanent Idealism
Although I am all for empirical and interdisciplinary researches, I believe there are certain questions that need to be tackled with traditional philosophical methods. They can be encapsulated with the notion of "second nature," which is an Aristotelian notion made popular by John McDowell (1996). Specific issues include meaning (vs. Dummett), experience (vs. Davidson), self-knowledge (vs. Wright), action (vs. Dreyfus), perception (vs. Burge), content (vs. Travis), and perhaps all of the above (vs. Brandom). In this context, I argue for "Immanent Idealism": the view that the world is within human subject’s discursive capacities. One important contrast of this position is Huw Price's "global expressivism." This line of research has rich implications about the mind-body problem, personal identity, action, causation, and animal minds.
