If we know that our world is necessarily the world we bring forth with others, every time we are in conflict with another human being with whom we want to remain in co-existence, we cannot affirm what for us is certain (an absolute truth) because that would negate the other person. If we want to coexist with the other person, we must see that his(sic) certainty - however undesirable it may seem to us - is as legitimate and valid as our own because, like our own, that certainty expresses his(sic) conservation of structural coupling in a domain of existence - however undesirable it may seem to us. Hence, the only possibility for coexistence is to opt for a broader perspective, a domain of existence in which both parties fit in the bringing forth of a common world.
