A second line of criticism targets the alleged perceptual priority of P-properties. According to the enactive approach, P-properties are “perceptually basic” (Noë 2004: 81) because in order to see an object’s intrinsic, 3D spatial properties it is necessary to see its 2D P-properties and to understand how they would undergo transformation with variation in one’s point of view. When we view a tilted coin, critics argue, however, we do not see something that looks—in either an epistemic or non-epistemic sense of “looks”—like an upright ellipse. Rather, we see what looks like a disk that is partly nearer and partly farther away from us. In general, the apparent shapes of the objects we perceive are not 2D but have extension in depth (Austin 1962; Gibson 1979; Smith 2000; Schwitzgebel 2006; Briscoe 2008; Hopp 2013).
