IB Philosophy — Liberty and rights

Topic 7.3 of IB Philosophy covers Liberty and rights, which is part of Unit 7: Political philosophy. Students explore key concepts including What are rights?, Positive vs negative liberty, Free speech and its limits. A strong understanding of liberty and rights is essential for IB Philosophy exams and builds the foundation for connected topics across the syllabus.

Exam technique guidePractice questions

Key concepts in Liberty and rights

Key Idea: Topic 7.3 asks the question that decides how much the state may do to you: what are your rights, what is freedom, and where may the law draw the line? These are the ideas we reach for whenever power meets the individual. Master this topic and you have a ready-made answer for Paper 1 Section B, a 25-mark essay where you're handed a claim about liberty or rights and told to 'Evaluate' it.

🕊️ The three big questions, one card each

Topic 7.3 at a glance

  1. 7.3.1 · What are rights? — Three kinds: legal rights (granted by law), moral rights (what you're owed as a person), and human rights (held simply by being human). The big fight: are human rights truly universal and inalienable, or a Western idea dressed up as global?
  2. 7.3.2 · Positive vs negative liberty — Two meanings of 'freedom'. Negative liberty is freedom FROM interference — being left alone. Positive liberty is freedom TO become yourself — having real power and resources to act, not just an open door.
  3. 7.3.3 · Free speech and its limits — Mill's harm principle: the state may restrict you only to prevent harm to others, never merely to protect you from yourself or to silence offence. The hard line is harm vs offence — and it decides most censorship debates.
Negative liberty is freedom FROM — no one interfering, the door left open. Positive liberty is freedom TO — actually having the power, resources and self-mastery to walk through it. A starving person is negatively free to buy food (no law stops them) but not positively free (they have no means). Almost every Section B question on liberty is really asking you to weigh the 'leave me alone' idea of freedom against the 'give me the power to act' idea.

✍️ Bring it together — a Section B question

IB-style questionEvaluate[25 marks]

Evaluate the claim that the state may restrict a person's freedom only to prevent harm to others.

Important: Describing views instead of evaluating the claim. Section B hands you a claim to weigh — don't just tour 'Mill thinks X, Berlin thinks Y.' Argue FOR the claim, argue AGAINST it, test its key word (here, 'only' and what 'harm' means), and reach a reasoned conclusion. A name earns nothing without its argument, and a top answer never ends on 'it's all subjective'.

✅ Check yourself

If you can answer these six, you have the spine of the whole topic.

What are the three kinds of right? Legal rights (granted by a legal system), moral rights (what you're owed as a person, whatever the law says), and human rights (held simply by being human, everywhere).

Universal and inalienable — or a Western idea? Human-rights talk claims rights are universal (everyone has them) and inalienable (can't be signed away). Critics reply it may export one culture's values as if they were global.

Negative vs positive liberty? Negative: freedom FROM interference — being left alone. Positive: freedom TO become yourself — having the real power, resources and self-mastery to act.

What is Mill's harm principle? The state may limit your freedom ONLY to prevent harm to others — never merely to protect you from yourself or to silence opinions people dislike.

Harm vs offence — why does the line matter? Mill's principle only works if harm is kept distinct from offence. If being offended counted as being harmed, almost any speech could be banned — so 'harm' must mean more than 'I don't like it'.

When can censorship be justified on Mill's view? Only where speech causes real harm to others (incitement, direct danger) — not for mere offence. Freedom of information is the default; restriction needs a harm to justify it.

Exam Tips

  • Political Philosophy is optional → Paper 1 Section B: a 25-mark essay with NO stimulus. You're handed a claim and told to 'Evaluate' it.
  • Find the load-bearing word in the claim ('only', 'always', 'never') and make evaluating it the spine of your essay.
  • Name a thinker ONLY with their argument — Mill, Berlin, the harm principle earn marks only when you use them to argue.
  • Always argue both sides and end on a reasoned conclusion, never a list and never 'it's just opinion'.

What you'll learn in Topic 7.3

  • 7.3.1 What are rights?
  • 7.3.2 Positive vs negative liberty
