“The Science of Logic” is Hegel’s most important work, where his dialectical method stands out in relief. The classics of Marxism-Leninism highly value this work of Hegel. Lenin wrote that “one cannot fully understand Marx’s Capital and especially its first chapter without studying and understanding Hegel’s entire Logic.” Hegel guessed the dialectic of things in the dialectic of concepts. Hegel’s dialectics is idealistic, which is why Lenin wrote: “Hegel’s logic cannot be applied in its given form; cannot be taken for granted. From it we must select logical (epistemological) shades, clearing it of the mysticism of ideas: this is even more work.” Hegel’s “Science of Logic” is given in a new translation.
