A phenomenological perspective, a semiotic perspective and a metaphysical perspective will produce different triadic ontologies.

And a meta-perspectival perspective might feel obessessive-compelled to arrange these triadic ontologies into a meta-triad. )O+

(A phenomenological perspective is one that organizes reality in terms of individual experience; a semiotic perspective organizes reality in terms of signs; a metaphysical perspective organizes reality in terms pointing beyond the direct experiences of human minds. Private experience; public experience; transcendent experience, respectively. 20th Century thought divided along these lines. Continental and analytic philosophy agreed on little except the importance of excluding metaphysical conceptions from their methods.)
