My general research interests are in the following areas: (1) philosophy of perception and consciousness, (2) metaphysics of space-time and quantum mechanics, and (3) their counterparts in Chinese philosophy. I currently focus on issues about time. Time presents a range of philosophical puzzles, since it is an area in which our ordinary experience and the world as conceived in the “scientific” image seem to conflict. When perceiving the most ordinary things, such as a bird’s singing a melody, there seems to be a special moment – the present – at which the bird is singing the newest note, and it seems that this special moment is to be filled up with even newer contents, while the bird’s singing the first note seems gone away into the more and more distant past. However, this everyday dynamic conception of time faces three important challenges: (a) that we do not have immediate experience as of presentness; (b) that our immediate experience as of presentness or temporal passage does not have metaphysical import; and (c) that special relativity does not have room for a non-solipsist, non-relative form of presentness or simultaneity. My current research is dedicated to finding novel ways to defend a dynamic conception of time (an ‘A Theory’) in the face of these difficult problems.
