 Debate over whether Hegel’s dialectical logic is logical may also be fueled in part by discomfort with his particular brand of logic. Unlike today’s symbolic logics, Hegel’s logic is not only syntactic, but also semantic (cf. Berto 2007; Maybee 2009: xx–xxv; Margolis 2010: 193–94). Hegel’s interest in semantics appears, for instance, in the very first stages of his logic, where the difference between Being and Nothing is “something merely meant” (EL-GSH Remark to §87; cf.  section 2  above). While some of the moves from stage to stage are driven by syntactic necessity, other moves are driven by the meanings of the concepts in play. Indeed, Hegel rejected what he regarded as the overly formalistic logics that dominated the field during his day (EL Remark to §162; SL-M 43–44; SL-dG 24). A logic that deals only with the forms of logical arguments and not the meanings of the concepts used in those argument forms will do no better in terms of preserving truth than the old joke about computer programs suggests: garbage in, garbage out. In those logics, if we (using today’s versions of formal, symbolic logic) plug in something for the P or Q (in the proposition “if P then Q” or “P → Q”, for instance) or for the “F”, “G”, or “x” (in the proposition “if F is x, then G is x” or “Fx → Gx”, for instance) that means something true, then the syntax of formal logics will preserve that truth. But if we plug in something for those terms that is untrue or meaningless (garbage in), then the syntax of formal logic will lead to an untrue or meaningless conclusion (garbage out). Today’s versions of prepositional logic also assume that we know what the meaning of “is” is. Against these sorts of logics, Hegel wanted to develop a logic that not only preserved truth, but also determined how to construct truthful claims in the first place. A logic that defines concepts (semantics) as well as their relationships with one another (syntax) will show, Hegel thought, how concepts can be combined into meaningful forms. Because interpreters are familiar with modern logics focused on syntax, however, they may regard Hegel’s syntactic and semantic logic as not really logical (cf. Maybee 2009: xvii–xxv).
