Therefore, once a single formal logic subject-predicate judgment is used to express the "Essence" of an object, it will immediately fall into the "Pure identity" with the predicate - that is, "Said is equal to not said" - this is the black what geer said: "Intelligence" in the form of subject-predicate judgment cannot grasp the "Reasonable object" of essence. According to hegel, in order to grasp the "Essence" of thinking, it must abandon the "Identical proposition" transformed by this formal logic judgment, and transition to the so-called "Speculative proposition" (spekulativer satz). That is to say, when expressing the essence of things, thinking needs to make "Inferences" (schluss) from the opposite of identity from a set of propositions, rather than a single proposition. And this inference expresses no longer the indifferent, "Pure identity" between the two entities, but the concrete, "Identity with difference". In this way, this inference can be truly knowledge that is both generally valid and enriches itself. In the above example, if it is expressed in terms of "Speculative proposition", it should be:
In the case of adding many different ghost mannequin effect service kinds of things, such as "5 liters of water plus 7 mermaids", "5 plus 7" is not necessarily "12"; only under the condition "The same kind of things add up" , they will be equivalent. That is: "5 plus 7 equals 12 of the same kind." because "Natural numbers" are originally defined from the concept that "Quantities are discontinuities in continuity". For example, under the continuous condition of "All fruits", 5 apples and 7 oranges can be 12 fruits.
Therefore, the proposition at this time is no longer the "Intellectual identical proposition" (noun = noun), but the "Speculative identical proposition" (noun = adjective + noun), which expresses the logical condition of "Identity". (logische bestimmung); and predicates are specified. And this "Adjective" ("Addition of the same kind") that connects the subject and the predicate also transcends the "Accidentality" and becomes the "Necessary connection" between the subject and the predicate, which is defined by the essence. "Universal". At this time, the proposition has become "Representing an entity by necessity". Only in this way can the subject "Get out" from the original "Pure identity" that has no stipulation, and then return to itself, re-establish itself as the "Recognized object" fixedness, and thus establish the "Concrete identity" with the predicate. .
