 The choice is between truth-value gaps and truth-value gluts: A truth-value gap is a statement with no truth-value, neither true or false (like undefined in Kleene’s strong three-valued logic), and a truth-value glut is a statement with several truth-values, e.g. both true and false (like in the paraconsistent logic LP). There are also arguments in favour of allowing both gaps and gluts, e.g. by letting the set of truth-values form of a bilattice (Fitting, 2006; Odintsov and Wansing, 2015). The simplest non-trivial bilattice has exactly four values, which in the context of truth-values are interpreted as: true, false, \(\bot\) (neither true nor false), and \(\top\) (both true and false).
