"My belief is that we do not have purpose a priori, and that life is void," You mean intrinsically, maybe before knowledge. A priori doesn't make sense in this context. "Why are we happy when a spouse gives birth? Why are we worried if a dear friend or companion is ill? Why do we shed tears at a loved one's wake? We feel because we developed a connection with the people around us. That is our purpose. If we cannot find a purpose within ourselves (above argument), we find purpose in preserving the life and happiness of the ones most dear to us (this argument)." Why are we happy when an enemy is killed? Why are we worried if a dear follows us in the dark? Why do we shed tears at a foe's triumph? We feel because we developed a hatred toward the people around us. That is our purpose. If we cannot find a purpose within ourselves (above argument), we find purpose in hating those whom we most hate (this argument).
