 One possibility is that, ultimately, all of the tangible qualities, with the exception of hot and cold, can be reduced to the spatial properties of objects (Armstrong 1962). Such a view could be  connected to recent work on the spatial content of touch (for instance,  views like those explored in Fardo et al 2018). Defending such a reductive claim involves making an important distinction between transitive and intransitive bodily sensation. The transitive sensations are those like warmth and pressure that have a sensory component as well as a real world property. Intransitive sensations do not have any non–sensational real world feature. This is one way to separate out pains, twitches, and tingles from perceptual touch proper. The spatial view then states that nearly all of the objective tangible features made available through transitive sensation are relational spatial properties. On this relational view of touch, all immediate tactual perception involves a relation holding between our body and objects in contact with it. A rough surface is one that is solid, has hardness, and a certain uneven shape. A smooth surface only differs in having a regular shape. Roughness and smoothness can be analyzed in terms of shape. A hard object is one that does not change its shape. A soft object changes its shape under pressure. Liquidity is defined as having a particular shape in particular circumstances. Pressure plays a role here, so the view also requires a spatial account of pressure. One possibility is that pressure is a quality that has a tendency to cause a change in the shape of the body. Stickyness could be when something remains in contact with the same spot on the skin, slippery things do not. Despite the possibilities for reduction here, many of these moves feel ad hoc and unsupported by the empirical evidence. A better account is needed.
