Abstract

The ability to anticipate events, to foresight, is an adaptive advantage. We humans use it all the time. Animals have a limited access to it. Positioning foresight in human evolution is a complex subject (Suddendorf, 2013). Why and how are humans, and not chimpanzees, performant in anticipating events? We propose here to address that question with an evolutionary scenario that links self-consciousness to anxiety management (Menant, 2018). The scenario positions self-consciousness as “the capability to represent one’s own entity as existing in the environment, like conspecifics are represented as existing” (making “thinking about oneself” possible). The scenario proposes that our pre-human ancestors were capable of some level of identifications with their conspecifics, and that its development has progressively brought our ancestors to represent themselves as existing in the environment like their conspecifics were represented, thus introducing self-consciousness. The scenario also proposes that identifications with suffering conspecifics have been the source of an important anxiety that had to be limited for evolution to continue. Some of our ancestors have not been able to limit that new anxiety. Their mental pain became unbearable. Their evolution was almost stopped, thus initiating the pan-homo split. Developing an ability to anticipate events has been a key contributor to anxiety limitation by providing information about the sufferings to come, and consequently allowing to limit and avoid them. In addition to that role of foresight in human evolution it is worth noticing that the associated chaining of mental events brings to propose foresight as an entry point to the concept of causality in human evolution. Regarding our chimpanzee cousins, the pan-homo split in the scenario positions them as not self-conscious, not capable of anticipation like humans are, and less anxious than humans. Continuations are proposed.
