Basic, key concepts of semiotic are surveyed en route to establishing signs, units of signification, as always dealing in relations. These relations are triangular and mediate. Signs span and mediate between the internality and externality of things, thing being defined as a composite of subjectivity and objectivity. Because signs are relational and mediate, identicality is postulated as the limit of the sign. Identicality is aligned with things-in-themselves, which are assigned to meta-reality, to associate semiotic and metaphysic. Mind, thought, world, and (...) reality are conceptualized in such a way as to link signs with experience. Experience is explained as being founded in relations and practices between things. These relations and practices are formulated in significations. From these signification relations experience is founded, and through experience identities are situated and selves emerge. Holding experience as being formative of and fundamental to reality, it is concluded that reality is best described as being constituted in signs and ultimately bound by significations and relations between things.
