approaching meta-physics

to avoid the essentialism of conventional universalist or relativist labels -- that is, the essentialist universality of both: universalists claiming that we're all essentially the same while relativists claim a different universal that we are all irredeemably different -- to avoid this, it seems best to me to approach meta-ethics in cultural theory through respective emical or etical analyses; respective of multiplicities of contexts (i.e., cultures and histories). in any case, it requires a vocabulary devoid of the essentialist underpinnings of the former two terms.
