ABSTRACT
This chapter discusses the common-sense notion of a single all-containing Space for granted and considers the exact cash value of that conception. It makes the simplifying assumption that one successive field are literally momentary. This is certainly not true, for a momentary field is something that can only be defined by Extensive Abstraction. The chapter views nearly all the general concepts that use in dealing with Space, like distance, direction, place and shape; come from sight, whilst the notion of one Space and the particular quantitative values which these general concepts assume in special cases are due mainly to touch and to movement. These visual experiences, however, need much supplementation before they can give rise to the traditional concept of physical Space. Wholly different parts of a perceptual object if the visual sensa, which are the appearances of the object to all, are optically present in wholly separate regions of the movement-continuum.
