The structure of freedom: System or Fugue?

Although the conflict between freedom and system (The concept which is derived from the Greek word συνίστημι) has been always the subject of philosophical debate, there were German idealists who first formulated the relation between these two concepts explicitly. Here the system, which guarantees the coherence of knowledge, is a subjective and rational foundation. But Heidegger in his later thought, passed through the concept of system which its structure is determined by mathematical order, and hence has absolutely subjective implications, and instead used the concept of fugue to refer to the structure of Being’s swaying, i.e. the enowning event (Ereignis). However, the concept of Fugue does not involve the same rules as system does, but this structure has its own order. The privileged feature of this order is preserving the unity components, while every component is also self-confident. It is notable that in this structure, the self-confidence of every component is even strengthen by its freedom. Thus, the concept of Fugue let Heidegger think of a systematic structure (fugue) which is not against of freedom, but also freedom is its foundation.
