An AQAL approach to the study of signs and symbols, where the referent of any sign is said to exist within a specific worldspace. By way of a quadrivium, Integral Semiotics associates the signifier with the Upper-Right quadrant, the signified with the Upper-Left quadrant, semantics with the Lower-Left quadrant, and syntax with the Lower-Right quadrant. See sign, signifier, signified, semantics, syntax, and referent.
