Final Answer:
The argument of Companions in guilt in meta-ethics suggests that even if there is no rational reason to think that something is ethical, it is irrelevant because there is also no rational reason to think logically. The connection between metaethics and metaepistemology is explored through Terence Cuneo's argument for metaethical realism, emphasizing the interplay between moral facts and epistemic facts. Additionally, the relevance of normativity in logic within metaethics, particularly concerning the normativity of logic, is considered.
Step-by-step explanation:
The argument of Companions in guilt within meta-ethics addresses the idea that the absence of a rational reason to believe something is ethical does not necessarily render it irrelevant, drawing parallels with the absence of a rational reason to think logically. The crux lies in the exploration of metaethics and metaepistemology, where Terence Cuneo's argument for metaethical realism becomes pertinent. Cuneo's master argument asserts a connection between moral and epistemic facts, forming the basis for his defense of metaethical realism. This interplay between moral and epistemic facts is crucial in understanding the broader implications of ethical and epistemological realism.
Terence Cuneo's argument is intricately linked to metaepistemological realism, forming a defense against various forms of metaepistemological anti-realism. The alignment of Cuneo's case for metaethical realism with metaepistemological realism underscores the interconnectedness of these philosophical domains. Moreover, the consideration of normativity in logic within metaethics adds another layer to the discussion, raising questions about the normative aspects of logical reasoning and their relevance to ethical considerations. This intersection broadens the scope of the discussion, emphasizing the complexity and interdisciplinary nature of philosophical inquiries into ethics, epistemology, and logic.
