+ | Let us denote by $\mathsf{descriptum}(p \sqcup q)$ the unobservable state of affairs described by the 'quantum disjunction' of basic physical propositions $p$ and $q$ describing mutually exclusive (`orthogonal') observable states. | ||
+ | No such disjunctively composed state of affairs is allowed by //Tractarian// postulate of unique mode of composition of states of affairs. | ||
+ | Quite the opposite holds true in the (realistic interpretation of) quantum mechanics: it allows mutually exclusive states of affairs of the same object and the same magnitude to co-exist. | ||
+ | If co-existence of orthogonal states is admitted, then a different kind of picture relation must be introduced to account for possibility of describing this kind of reality. | ||
+ | A new logico-metaphysical situation appears when metaphysics allows for disjunctive composition of states of affairs and when logic accepts the possibility of linguistic representation of the disjunctive composition. | ||
