The purpose of this paper is to corroborate the scientific character of Hegel's dialectics from the cognitive perspective, via textual interpretation of both his "Science of Logic" and "Encyclopaedia Logic", to clarify the meaning of dialectics which was purported to "have exerted as much influence or occasioned as much controversy as this method." My conclusion attunes with Michael Forster who assigns a certain primacy to the dialectic of "Science of Logic" over that of "Phenomenology of Spirit", in that as the form of the pure thought, the dialectic of "Science of Logic" rests solely on the nature of the pure essentiality which constitutes the content of Logic.
