There is a familiar debate between Russell and Strawson concerning bivalence and "the present King of France." According to the Strawsonian view, "The present King of France is bald" is neither true nor false, whereas, on the Russellian view, that proposition is simply false.
Engaging this rich multi-lingual-cultural field, Aviva Taubenfeld charts Cahan's mode of "translinguification," while Sara Blair notes "the energetic bivalence of Cahan's dialect" as part of his "collage aesthetic," in the process revealing the implicit modernist aspect of Cahan's late-nineteenth-century fictions.
The first step on the journey is to realize that the key assumption of classical logic makes every proposition absolutely either true or false, an assumption called the principle of bivalence. (30) Multivalent logic instead allows propositions to be both true and false to a degree, so they can take on middle values of truth.
(10) Note the difference between this statement and the law of bivalence, which says that, for any proposition P, either P is true or P is false.
In such work, the authors emphasize that logics is applied to those "vague and indefinite social facts" and remind that it is "not only a method, but it implies a new world vision that focus not only the bivalence, but also the polyvalence and, in this regard, it challenges the "probability monopoly" of the classical Aristotelian logic about the world".
Propositions about the law can be true or false, even if the principle of bivalence does not hold with respect to them.

Selon qu'on la considere en amont ou en aval de la decision judiciaire, cette idee de One Single Right Answer renvoie toujours a la notion trompeuse de bivalence juridique.
Compared with similarly sized and monovalent Li+ ion, [Mg.sup.2+] ion has a stronger polarization due to the bivalence. A fundamental challenge of magnesium intercalation in inorganic hosts is the difficulty of [Mg.sup.2+] insertion and the slow kinetics of [Mg.sup.2+] diffusion [13, 14].
What kind of clear understanding can we expect to attain, however, if both determinism and its opposite are equally non-indicative of reality--if reality escapes logical bivalence (the theory that every meaningful proposition is either true or false, but not both)?
The ambivalence of our approach is justified by both bivalence communication, in generally, and also by bivalence own to intercultural communication, it meets both aspects: both affect the thinking of the party and the production and exchange of meanings (always culturally determined).
However, our inability to affirm bivalence is not the result of our affirming a truth-value gap.
