ABSTRACT
Space is the product of human agency, experienced as the ability to act and change something in one’s world, for example, to move bodily in several directions. So conceived, space cannot exist without human actors who recognize possibilities, choose among them, and experience the consequences of their actions. Possibilities are conceptual, but not entirely subjective.To act with some degree of confidence requires, in James Gibson’s (1979) sense, that actions are afforded or supported by the environment in which they are performed – presuming no knowledge of the objective or actor-independent nature of that environment. Space is recognizable by its limits, where actions thought to have been possible are not afforded, expectations associated with these actions are not met and obstacles that are encountered require removal, circumvention, or acceptance as a constraint.
