Can someone provide for a layman a positive definition of space? I am looking for a definition of what space is, rather than a definition of what space relations to. So far I can only perceive space as "the distance between 2 non spatial entities" or "'the absense of a non-spatial (i.e. physical) entity". Obviously, at least the second of these definitions is circular and unsatisfying. As a second question , but without complicating the above primary question, would someone try to give a positive (rather than a relationship or functional) definition of time? Thirdly, as a bonus, could anyone perceive of a logic that included action but was not limited to a progression in the sequence of time?
