With humans, unlike with other beings, there is not just a generic question of what we are, but of who each is individually. Action and speech are always between humans and directed toward them, and it generates human relationships. Diversity among the humans that see the action makes possible a sort of objectivity by letting an action be witnessed from different perspectives.
Human existence is marked by an inquiry into the distinctiveness of each individual, setting it apart from other beings. Human interaction and expression are always between individuals and aimed at them, giving rise to interpersonal connections. The varied perspectives of multiple humans enable a nuanced understanding of actions.
