 Russell takes all of these different entities to be neutral (in the Neither Sense); and he takes all of them to be  events[7],  where an event is understood as “something occupying a small finite amount of space–time” (Russell 1927b: 287). The noise and the color patch considered above are typical examples of events. A Russellian event is absolute, in C.D. Broad’s sense: “it should not itself be a state of invariance or of change in the qualities or relationships of any thing” (Broad 1959: 739; see also Maxwell 1978: 385–6 on pure events). According to Russell, physics teaches that events “just happen, and do not happen ‘to’ matter or ‘to’ anything else” (Russell 1927b: 289). This means that we must not think of mental events (or any events) “as consisting of motions of bits of matter” (Russell 1927b: 292), for “matter in motion…is not an event in our sense” (Russell 1927b: 296).
