Reality consists in a plurality of events. Mental events are not distinguished from material events. Sense data relate both to objects they constitute as physical facts
and to the minds that perceive them as mental facts. Sense data are subjective (i.e., they do not exist unperceived). Yet "there really are objects other than ourselves and our sense data which have an existence not dependent on our perceiving them." These objects are "perceptual objects" or "logical constructions" rather than physical being as such.
