Abstract
An adequate interpretation of concept of the propensity to communicate will thus lead us to interpret in this concept a possible formalization of the notion of the specious present, introduced into the field of psychology by William James at the end of the 19th Century. In this chapter, the authors introduce some aspects of the concept of time that their model operates under. While situating the actors in relation to each other in the network space, their propensity to communicate also indexes the future opportunities that are open to them by their past trajectories. The authors conclude with a discussion of a supposed “ancestrality's paradox”, according to which such a primacy would pay no heed to ignoring events located in a temporality prior to the appearance of any life on earth, and well before that of Homo habilis.
