Core Principle Breakdown

Chapter 1’s harm principle is the book’s backbone. It states that individual action should only be restricted if it causes harm to other people. Write this principle on a flashcard and quiz yourself daily until you can recite it without notes.

Scope of the Book

Mill explicitly defines the book’s focus in Chapter 1: it covers civil and social liberty, not political freedom or the structure of governments. This means he’s concerned with how social norms and state laws limit individual choice, not how to structure democratic systems. Use this before class to clarify any confusion about the book’s purpose during discussion.

Threats to Liberty

Mill identifies two main threats to individual liberty in Chapter 1: overbearing government and oppressive majority opinion. He argues that majority rule can lead to a tyranny of the majority, where popular norms suppress minority voices. Make a 2-column list of examples for each threat to use in essay drafts.

Rejection of Paternalism

Mill rejects paternalism, the idea that the state or society can restrict freedom for a person’s own good. He argues that individuals are the practical judges of their own interests, even when they make choices others disagree with. Note 1 real-world policy that reflects paternalism to discuss in class.

Link to Subsequent Chapters

Chapter 1 sets up the rest of the book by outlining the arguments Mill will develop in later sections. It teases discussions of freedom of speech, individual conduct, and the role of government. Draw a flow chart that connects Chapter 1’s thesis to 2 topics you see listed in the book’s table of contents.

Modern Relevance

Mill’s Chapter 1 framework remains relevant to debates over free speech, social media moderation, and public health policies today. Pick one modern debate and draft a 3-sentence analysis of how the harm principle applies to it. Use this before essay drafts to build a strong evidence base.
