How many times during the course of your life have you created a social or personal reality or embraced one created by others? By this I am not referring to an imaginary playmate or fantasy job or such but, rather, to a reality or fact based on mutual agreement or assent.
Sound crazy? It isn’t. The imminent philosopher John Searle actually devoted part of a whole book to the thesis that there are 2 kinds of facts: Those that are facts no matter who observes them, and then there are those that only need people’s agreement or assent to them. A fossil ammonite, for instance, is a physical object that remains a fossil ammonite no matter who looks at it or holds it. A church group’s claim that an archangel hovered over their last meeting is a mental reality to those who perceived it but cannot be demonstrated to those who do not share this perception/belief-based perspective (The same can be said of some treatments and diagnostic techniques in the world of complementary-alternative medicine).
