Overview of Natural Law Theory as foundational in legal philosophy
Distinction between natural law and legal positivism
Historical context: Natural law theory predates legal positivism, which emerged as a self-identified approach in response to natural law.
Core Concepts of Natural Law Theory
Definition: The idea that there exists a connection between normative judgments and legal judgments.
Significance of normative judgments in understanding what the law is:
Some theorists argue that normative judgments are essential in determining legal content.
Distinctions within Natural Law
Different interpretations of what constitutes natural law:
Moral Theories:
Theories that assert the ability to know the moral law through reason alone.
Contrast with theories dependent on divine revelation for moral knowledge.
Human Nature-Based Theories:
Theories suggesting knowledge of moral reality can be achieved by studying human nature, leading to rules governing human interactions.
Opposed to the idea that moral statements must be disconnected from human descriptions.
Understanding Human Nature in Natural Law
Example of human interaction and nature:
Assertion that people are inherently social beings.
Consequence: Poor relationships lead to negative outcomes in life, guiding us in how we treat others.
Connection Between Normative and Legal Judgments
Definition of normative judgments:
Judgments about how the law ought to function, potentially encompassing wider ethical considerations beyond personal conduct.
Theoretical aim of promoting living together in freedom while focusing primarily on legal and political interactions.
The Alleged Connection: Normative and Legal Judgments
Classic slogan: "An unjust law is not law."
Alternative phrasing by Murphy: "Necessarily law is a rational standard for conduct."
Interpretations of Murphy's Thesis
Strong Reading:
Assertion that any law viewed as unjust does not qualify as law at all.
Example: If a law mandates harming an innocent person, then disobeying it is seen as an action aligned with justice, revealing its lack of legal standing.
Evaluating Human Activities:
Application of judgment to various domains:
Healthy vs. unhealthy plants: Determined by inherent properties, not merely by utilitarian purposes.
Definitions of good and bad doctors: A doctor whose practice involves harm is both morally and professionally lacking.
Assessing plays in sports: Execution can be poor even if outcomes seem favorable due to chance.
Critique of Unjust Laws
Argument presented by Murphy supporting natural law theory:
Establishing laws must align with the intention of furthering the common good.
Central Cases in Legal Definition:
Two methodologies for defining law:
Checklist Method: Criteria established to categorize something as a particular type (e.g., classic cars).
Central Case Method: Identifying a central example (e.g., obedience due to moral motivation) to evaluate legality.
Emphasis on the reasons behind laws, suggesting a deeper understanding of their legitimacy.
Legislative Intent and Common Good
Natural law viewpoint on legislation:
Laws are instruments to promote the common good.
Real-world implications: Instances where oppressive regimes (e.g., Nazis in Poland) fail to establish true law, instead resorting to terror.
Justice and Legal Interpretation
Questioning the ability of legal professionals and citizens to act on the basis of justice:
Disagreement amongst natural law theorists regarding when justice supersedes existing law or allows deviations.
This theme will be explored in detail when evaluating various theorists surrounding natural law.
