from University of Tokyo 1S Law and Society Legal System Theory
- Introduction to Luhmann’s Legal System Theory
- This theory attempts to reconstruct legal theory based on systems theory.
- It is grounded in the field of sociology of law.
- Using the framework of methodological dualism, it deals with the world of existence rather than the world of oughtness, similar to Weber’s approach.
- How do we perceive society (the world of existence)?
- Society is seen as a collection of various systems such as the academic system, economic system, and legal system.
- These systems interact with each other, for example, politics influencing legal codes.
- In other words, law is seen as one of the systems.
- But there are problems with this perspective on the legal system (blind spots).
- The program that determines legality or illegality cannot determine if it itself is legal or illegal.
- Specifically, it cannot determine if the Japanese Constitution is legal or illegal, which creates a blind spot.
- If we force the issue, we end up with a paradox where being legal is illegal.
- There are two ways to handle this paradox:
- First-order and second-order observation.
- Observation is divided into two parts.
- First-order observation: what
- This refers to the normal observation of whether one’s own actions are legal or illegal.
- Second-order observation: how
- This looks at how the first-order observation was conducted relative to other observations.
- Is it appropriate to paraphrase “meta observation”?
-
It means being able to observe the fact that “one cannot observe something one cannot see.”
- Also known as “unfolding of paradoxes.”
- As a premise, law is fundamentally autopoietic (it generates itself).
- I can’t think of a specific example here. Is it all laws enacted by the parliament, so they are all allopoietic?
- However, the basis for determining legality or illegality is externalized to other systems (e.g., the political system).
- This is what makes it allopoietic.
- Specifically, the constitution is law.
- In this way, the paradox is resolved by saying “I don’t know.”
- This thinking is further developed in the concept of “structural coupling.”
- The legal system depends on other systems such as the political system (as mentioned earlier).
- Conversely, the political system also depends on the legal system.
- This interdependence between systems is called “structural coupling.”
- First-order observation: what
- Observation is divided into two parts.
- Based on these ideas, we consider the closure and openness of systems.
- Closure
- First-order and second-order observation.
- Openness
- Unfolding of paradoxes.
- This leads to externalization.
- Re-entry
- Externalizing and reflecting on how the system is perceived by external systems.
- Unfolding of paradoxes.
- Closure
- First-order and second-order observation.
- Luhmann’s worldview is a nested structure.
- What kind of worldview?
- First, there is the theory of System (Luhmann) as a form of academic observation.
- (In line with the definition of theory)
- Within that worldview, there are various systems such as the academic system and the legal system.
- By organizing where various legal-related studies and theories fit within these systems:
- Legal System:
- Communication chains dealing with norms (oughtness, legality/illegality).
- Definition: Restricting other possibilities when alternative actions are observed.- It seems to be about limiting the potential to kill people when there is a possibility of doing so (blu3mo).
- Communication chains dealing with norms (oughtness, legality/illegality).
- Legal System:
- First, there is the theory of System (Luhmann) as a form of academic observation.
- What kind of worldview?
- Specifically, it involves:
- Legal Hermeneutics:
- Discussing how to interpret and should interpret laws.
- Organizing the interpretation and application of laws.
- Print 1, Chapter 5, page 5.
- Methodology:
- Discussing the methods of interpretation, such as Textual Interpretation.
- Rn23.
- Reflection Theory:
- Also known as “legal theory”.
- Discussing how the legal system should interact with other systems while maintaining consistency.
- If it is a discussion about how one should be, it does have a sense of “reflection”.
- These are more abstract discussions rather than specific cases (from the perspective of Second Order).
-
The result of the differentiation of legal expertise at the observation level of second order.
-
- However, they are all discussions about “norms” and can be positioned as actions within the legal system.
- Legal Hermeneutics:
- Academic System:
- A chain of communication dealing with truth and falsehood.
- It is not about norms, but about truth and falsehood.
- Specifically, it involves:
- Legal Philosophy:
- Looking at the legal system from the perspective of the academic system.
- A discipline that seeks to achieve justice.
- Print, page 4.
- There are several variations.
- Details are written in “Understanding Legal Philosophy”.
- The first variation is called “National Philosophy”, the German one.
- The second variation is called “Deliberative Theory”.
- The public opinion of civil society is reflected in the parliament/laws, and from there…
- Both of these, if seen from a systems theory perspective, focus too much on the legal system and political system, and Vesting criticizes them for not considering the relationship between law and economics.
- Discussing what justice is.
- This is not about “norms”..? (blu3mo)(blu3mo)❓
- Sociological Jurisprudence:
- Discussing how the legal system interacts with other systems while maintaining consistency.
- The difference from Reflection Theory is whether it is a discussion of “norms” or a discussion of “existing” (ought to be).
- This is what Luhmann dealt with.
- Legal Philosophy:
- In summary, “sociological jurisprudence” presents a worldview that organizes various things related to law and also determines the position of “sociological jurisprudence” within it (blu3mo).
- It is an Nested Structure like this (blu3mo).
- At least now I understand what Luhmann wants to talk about (blu3mo).
- Vaihinger’s criticism of this:
- Criticizing the worldview based on the system theory itself.
- Everyday “language” cuts across this system.
- Well, of course, it’s difficult to distinguish between “existence” (academic system) and “ought to be” (legal system) in everyday life (blu3mo).
- I thought the same in the discussion of “How Wikipedia gets to define what’s true online”.
- So, doesn’t theory also cut across the legal system and the academic system?
- I think what he is saying is true, but I don’t understand the meaning of “so” (blu3mo)❓
- Isn’t legal hermeneutics, for example, not something that exists only in the legal system, but something that cuts across the academic system and the legal system?
- There are definitely interactions between the theories of physics (purely academic) and Legal Hermeneutics, right? That’s the criticism.
- In that case, “legal theory” is something that exists in the space that cuts across the academic system and the legal system.
- Wait, didn’t you just criticize the worldview of system theory? (blu3mo)
- If you take the original interpretation of “legal theory”, it doesn’t capture the partial overlap well, so it’s better to consider it as something that cuts across (blu3mo).- As a thought, is mathematics then part of the legal system? (blu3mo) ❓
- It’s not about existence, but rather a discussion based on assumptions.
- In the historical flow of philosophy:
- Ancient times: Plato and Aristotle
- Do they consider existence as something that can be thought of as existing?
- It’s like digging out an ideal theory that exists somewhere in this world.
-
- I don’t really understand it, but I’ll link it anyway. (blu3mo)
- Do they consider existence as something that can be thought of as existing?
- Modern times: Nietzsche, Heidegger, and Luhmann
- Do they consider existence as something that creates something new?
- Including theories.
-
-
By setting each “existence” perspective, what can be gathered within that field of view is seen as “existence.”
- Is it a story that each system, as an existence, has a field of view (binary code) and creates a new “existence” by gathering various existences? (blu3mo) ❓
- I understand it abstractly, but I don’t understand anything specifically. (blu3mo)
- Do they consider existence as something that creates something new?
- Ancient times: Plato and Aristotle
- I want to understand it through programming. (blu3mo)
