What happens

The chapter presents a single epigraph from Bishop Butler: 'Everything is what it is, And not another thing.' This concise statement establishes a foundational principle of identity and logical clarity, suggesting that things have an intrinsic nature that cannot be reduced to or confused with something else.

Themes in this chapter

  • Method of Ethical Reasoning

    The epigraph underscores the importance of precise definitions and logical clarity in ethical reasoning, rejecting equivocation or reductionism.

Key passages

  • Everything is what it is, And not another thing.

    Each thing has its own distinct identity and cannot be mistaken for something else.

    This principle of identity serves as a logical foundation for Moore's critique of naturalistic fallacy, where ethical terms are wrongly equated with natural properties.
