§ 106. The demonstrative method, in order to bring about its proof of necessity, has a choice of many different ways. But we must not imagine, either that there are an unlimited number, and that it is only a chance which one we shall take; or that they have no connection among themselves, and run, as it were, side by side. It is not, however, the business of Pedagogics to develop different methods of proof; this belongs to Logic. We have only to remember that, logically taken, proof must be analytic, synthetic, or dialectic. Analysis begins with the single one, and leads out of it by induction to the general principle from which its existence results. Synthesis, on the contrary, begins with a general which is presupposed as true, and leads from this through deduction to the special determinations which were implicit in it. The regressive search of analysis for a determining principle is _Invention_; the forward progress of synthesis from the simple elements seeking for the multiplicity of the single one is _Construction_. Each, in its result, passes over into the other; but their truth is found in the dialectic method, which in each phase allows unity to separate into diversity and diversity to return into unity. While in the analytic as well as in the synthetic method the mediation of the individual with the general, or of the general with the individual, lets the phase of particularity be only subjectively connected with it in the dialectic method, we have the going over of the general through the particular to the individual, or to the self-determination of the idea, and it therefore rightly claims the title of the genetic method. We can also say that while the inventive method gives us the idea (notion) and the constructive the judgment, the genetic gives us the syllogism which leads the determinations of reflection back again into substantial identity.
