What Sensations Do We Derive From an Object?

We cannot begin to state what different sensations we shall derive from a given object under different circumstances, unless we regard the object and our body as both in one physical space. We only hear or smell or taste an object when we are sufficiently near to it, or when it touches the tongue, or has some suitable position in physical space relatively to our body. Our sense data are situated in our private spaces - either the space of sight, or the space of touch, or such figure spaces as other senses may give us. Thus we may assume that there is a physical space in which physical objects have spatial relations,. corresponding to those which the corresponding sense data have in their private spaces.
