 Hegel provides the most extensive, general account of his dialectical method in Part I of his Encyclopaedia of Philosophical Sciences, which is often called the Encyclopaedia Logic [EL]. The form or presentation of logic, he says, has three sides or moments (EL §79). These sides are not parts of logic, but, rather, moments of “every concept”, as well as “of everything true in general” (EL Remark to §79; we will see why Hegel thought dialectics is in everything in  section 3).  The first moment—the moment of the understanding—is the moment of fixity, in which concepts or forms have a seemingly stable definition or determination (EL §80).
