Crucially, we argue that seeing objects requires seeing the groupings that compose them, and that seeing groupings requires seeing the spatial field that grounds them. Even the most basic feeling of spatial extendedness implies rich phenomenal structure. It follows that much of what we see cannot be used, reported, or remembered. And yet we see it.
