The exposition or constitution of the " idea " is the work of the Logic. As the total system falls into three parts, so every part of the system follows the triadic law.
Fichte cannot be said to have developed a logic, but this rhythm of thesis, antithesis and synthesis, foreshadowed in part for Fichte in Spinoza's formula, " omnis determinatio est negatio," and significantly in Kant's triadic grouping of his categories, gave a cue to the thought of Hegel.
