How Singapore Education Works | International Baccalaureate® (IB) Philosophy HL vs SL 2027: Being Human, Prescribed Text and Paper 3

—

by

eduKate Asia
Three students sit around open books and worksheets at a classroom table, reading, writing and discussing the work together.

Quick answer: IB Philosophy SL studies the core theme Being human, one optional theme and one prescribed philosophical text. HL studies two optional themes and adds Philosophy and contemporary issues. SL assessment is Paper 1 (50%), Paper 2 (25%) and a philosophical analysis (25%); HL adds Paper 3 and changes the weightings to 40%, 20%, 20% and 20%. The internal assessment is a 2,000-word analysis of a non-philosophical stimulus.

This Singapore-focused guide explains what students actually study, how the prescribed text works, why Paper 2 is open book, what HL Paper 3 assesses and how to turn a film scene, photograph or poem into a philosophical question.

What is IB Philosophy?

IB Diploma Programme Philosophy is a systematic and critical inquiry into questions about being human, knowledge, reality, ethics, freedom and how we should live. Students learn to examine arguments, identify assumptions, clarify concepts and assess reasons. It is not simply a collection of famous quotations or a class in expressing personal opinions.

The course first assessed in May 2025 asks students to engage actively in philosophical activity. All students study the core theme Being human, one optional theme at SL or two at HL, and one prescribed philosophical text. They also complete a philosophical analysis of a non-philosophical stimulus.

At HL, students undertake the additional extension Philosophy and contemporary issues, which explores pressing questions connected with technology and the environment and asks students to reflect on the nature and methods of philosophical inquiry. HL therefore involves more than taking the same lessons and writing longer essays.

The core theme: Being human

Being human is compulsory at both levels. It asks students to examine identity, freedom and human nature, including what distinguishes humans from other species, where the boundaries of personhood lie and whether animals or machines could count as persons.

These questions connect philosophy to ordinary life. Consider an AI system that appears to hold a conversation, remember information and respond to emotion. Does fluent language prove understanding? What makes an entity a person? Is consciousness required for moral status? Different philosophical positions may offer different answers, but an answer needs to explain its assumptions and defend its reasoning.

The topic also invites careful consideration of human identity. Is a person defined by memory, body, relationships, consciousness, social recognition or some combination? A student’s task is to understand why the concepts matter and whether a proposed account can handle difficult cases.

A good discussion does not pretend that a complicated problem has a simple answer. It makes the disagreement intelligible: which definition is being used, what evidence or reasoning supports it, and which objection might undermine it?

Which optional themes can students choose?

The IB lists seven optional themes: aesthetics, epistemology, ethics, philosophy of religion, philosophy of science, political philosophy and social philosophy. SL students study one optional theme; HL students study two. The school chooses the themes it offers, so students should check the actual course plan rather than assume all seven are available at every campus.

Aesthetics asks about beauty, art, interpretation and artistic value. Epistemology investigates knowledge, justification, belief and the limits of what can be known. Ethics considers right action, duties, consequences, virtues and moral responsibility. Philosophy of religion explores questions about belief, faith, religious experience and arguments about the divine.

Philosophy of science examines scientific knowledge, explanation, evidence and the status of theories. Political philosophy explores authority, justice, freedom, equality and the state. Social philosophy considers social relationships, institutions, identity and how individuals are situated within communities.

The best theme is not necessarily the one that sounds most familiar. Choose based on the student’s curiosity, willingness to read and discuss difficult arguments, the teacher’s expertise and the school’s actual teaching choices.

Why the prescribed philosophical text matters

Students study one text selected from the IB’s prescribed list. The list includes works by philosophers from different traditions, such as Plato, Lao Tzu and Martha Nussbaum. The text is not simply a source of quotations to memorise; it gives students an opportunity to follow a sustained philosophical argument in its own terms.

A good reader identifies the author’s main question, definitions, premises, examples and conclusions. They then ask whether each step is persuasive and what objections could be raised. A candidate who quotes a famous sentence without explaining the argument around it has not demonstrated close philosophical understanding.

Paper 2 is based on the prescribed text and is an open-book examination. Candidates may bring one clean copy of the selected text from the IB list, without annotations or highlighting. This is not permission to bring their own notes, a commentary or an annotated study guide. Students must check the precise examination instructions for their session.

What changes between Philosophy SL and HL?

Both levels study Being human, one or more optional themes according to the level, one prescribed text and the philosophical analysis internal assessment. SL requires one optional theme; HL requires two. HL also studies Philosophy and contemporary issues, including the nature, function, meaning and methodology of philosophical activity.

The published assessment weights are different. At SL, Paper 1 is 50%, Paper 2 is 25% and the internal assessment is 25%. At HL, Paper 1 is 40%, Paper 2 is 20%, Paper 3 is 20% and the internal assessment is 20%. Paper 3 is HL-only.

Philosophy SL is not an easier version in which students may simply state opinions. Both levels require precise argument, conceptual clarity and the ability to consider objections. HL adds breadth and a further kind of reflection on doing philosophy itself.

Paper 1: philosophical questions and arguments

Paper 1 assesses the core theme and the optional theme or themes. Section A uses stimulus-based questions on Being human. Section B contains essay questions based on the optional theme content. SL candidates answer one Section A question and one Section B question; HL candidates answer one Section A question and two Section B questions.

The paper rewards argument rather than a list of views. A student should define the key concept, explain the position being examined, provide an example and consider a serious objection. They should then make a reasoned judgement that follows from the discussion.

For example, an ethics question about whether a decision is right because it produces the best consequences should not stop at describing consequentialism. A strong response might examine how consequences are measured, whose welfare counts, whether rights can be overridden and whether the theory can handle uncertainty.

Paper 2: writing about the prescribed text

Paper 2 is a one-hour open-book examination at both levels, worth 25% at SL and 20% at HL. Students select one question connected to the prescribed philosophical text and answer both parts of that question.

The first part typically asks the candidate to explain or analyse a philosophical idea from the text. The second invites a more developed discussion that can draw on the student’s wider philosophical understanding. A response should show accurate comprehension of the author’s position rather than projecting a modern opinion onto the text.

A useful revision approach is to map the text: central question, core concepts, main argument, supporting reasons, assumptions, likely objections and possible responses. Then practise applying the argument to a new example without losing the author’s meaning.

Because the exam permits a clean copy of the prescribed text, candidates should learn how to navigate the text itself. The permitted copy is not a substitute for understanding, and students cannot write or highlight their own notes in it.

Paper 3: the HL extension

Paper 3 is taken by HL candidates only. It lasts 1 hour 15 minutes and contributes 20% of the HL grade. Students answer a two-part question based on an unseen philosophical text. In a given session, the text focuses on either philosophy and technology or philosophy and the environment.

Part A asks the candidate to explain an issue or concept raised by the unseen text, using the text and their own knowledge. Part B focuses on the nature, function, meaning and methodology of philosophy. It asks students to reflect on philosophical activity rather than simply repeat a memorised definition of a philosopher’s theory.

A strong response identifies the central issue, explains the author’s argument and then shows how philosophical inquiry helps investigate the problem. The candidate may consider what counts as a good reason, how a concept is clarified, what makes a question philosophical and how a claim can be challenged.

This is one reason HL candidates should maintain a record of the philosophical work they do in class: questions they investigated, disagreements they explored, methods they used and how their views changed after considering objections.

The internal assessment: analysing a non-philosophical stimulus

Both SL and HL students complete a philosophical analysis of a non-philosophical stimulus. It contributes 25% at SL and 20% at HL. The written analysis has a maximum of 2,000 words, excluding the bibliography or references and the required copy or description of the stimulus.

A suitable stimulus might be a poem, novel extract, play, film scene, photograph, painting, cartoon, advertisement, newspaper article or online item. The student identifies a philosophical issue raised by the material and analyses it philosophically. The stimulus is not itself a philosophical treatise; the learner must show the philosophical problem within it.

For example, a film scene might depict a person choosing between loyalty to a friend and a duty to tell the truth. The philosophical analysis could examine whether moral duties can conflict, how intention relates to responsibility or whether loyalty is a virtue in that situation. Simply reviewing the film’s plot would not answer the task.

The guide specifies a 1,000-word maximum extract from a novel or play for this purpose, and for television or radio a section of no more than 10 minutes and no more than two scenes. The stimulus must be accurately referenced and included or described as required.

How to choose a stimulus and identify a philosophical issue

Start with material that genuinely raises a question, not a source chosen only because it mentions the word “ethics”. A photograph can raise questions about representation, knowledge or responsibility; an advertisement may raise questions about manipulation, autonomy or desire; a film scene may expose a tension between freedom and social rules.

Write the philosophical issue as a question that can be analysed. “Is this image interesting?” is not enough. “Can a person’s identity be reduced to how others perceive them?” is a more promising philosophical issue if the stimulus gives a clear reason to investigate it.

Then make the link explicit. Explain which details of the stimulus raise the issue and why the issue is philosophical. Develop the argument through concepts, reasons and objections. Do not force a predetermined theory onto the material if the stimulus does not support it.

A student should keep the investigation focused. A 2,000-word limit does not allow an essay to survey every possible branch of philosophy. The best analysis makes one question clear and examines it deeply.

What does philosophical analysis look like?

Philosophical analysis involves clarifying a question, defining important terms, examining assumptions and developing reasons. It distinguishes an assertion from an argument and an example from evidence. The candidate should explain why a view might be reasonable and what makes it vulnerable to criticism.

Imagine the claim: “People should always be free to choose for themselves.” The philosophical work begins by asking what freedom means, whether all choices are equally autonomous, and how a choice may affect another person’s rights. A counterexample might involve coercion, addiction or serious harm. The candidate should not simply say freedom is important; they must examine what the claim means and whether it can be defended.

A clear structure is useful: identify the issue, explain the key concepts, develop one or more arguments, evaluate objections and reach a reasoned conclusion. The conclusion should reflect the analysis, not introduce a new theory at the last moment.

How to avoid common Philosophy mistakes

One frequent mistake is treating a philosophical essay as a personal reflection. Personal experience can illustrate an argument, but it does not replace reasons that another person can examine. Another mistake is name-dropping philosophers without accurately explaining their positions.

Students may also use technical vocabulary without defining it, or assume that a counterargument is defeated simply because they disagree with it. A serious objection needs to be represented fairly before the student responds. The aim is not to win a debate by force of confidence; it is to clarify which position is better supported.

Finally, do not confuse uncertainty with failure. A philosophical conclusion can be qualified. The candidate may explain why one position is more persuasive under certain conditions while acknowledging a limitation. Precise qualification often shows stronger thinking than an absolute claim that ignores complications.

How Philosophy connects to life in Singapore

Singapore provides many questions that can be examined philosophically: fairness in education, public space and freedom, cultural identity, multilingualism, technology and privacy, duties to family, environmental responsibility and the relationship between individual and collective well-being.

A student discussing education fairness should clarify whether fairness means equal resources, equal opportunity, equal outcomes or a system that recognises different needs. These ideas can lead to different policy conclusions. A student discussing data privacy should distinguish consent, control, harm, property and the public interest.

The classroom should create room for disagreement while requiring respectful reasoning. A philosophical argument is not a personal attack, and a student’s cultural or religious background should not be treated as proof that they hold a particular position. Students should learn to examine arguments and listen seriously to others.

How to prepare for Philosophy examinations

Begin with the precise syllabus and the school’s selected optional theme or themes and prescribed text. Build a map of each theme’s central questions, key concepts, arguments and potential objections. Do not spend equal revision time on topics the school has not selected.

Practise short explanations first: define a concept, state an argument, give an example and identify one objection. Then write timed essays using the command term and question focus. For Paper 2, read the prescribed text closely and practise both parts of a question. HL students should additionally practise analysing unseen text and reflecting on the process of philosophical inquiry.

For the internal assessment, agree the stimulus and scope with the teacher early. Keep references and drafts, respond to the teacher’s permitted feedback and ensure the final analysis remains the student’s own work.

Does Philosophy help with Law, Politics or other university courses?

Philosophy develops skills that may be useful in law, public policy, politics, economics, psychology, humanities and many other fields: analysing arguments, clarifying definitions, evaluating evidence, considering objections and communicating conclusions. These are transferable skills, not a professional qualification.

Universities set their own subject and admission requirements. An IB Philosophy result does not automatically replace English, Mathematics or other prerequisites. Students considering Law in Singapore should still check NUS and SMU’s English grades, application ranking, tests and interviews; studying Philosophy may be useful but is not a guarantee of admission.

Choose the subject because the learner is willing to engage with complex questions, read carefully, write precisely and revise their reasoning. That is a stronger foundation than choosing it because someone claims it is an easy source of Diploma points.

Philosophy subject and assessment checklist

  • Confirm the Philosophy course guide first assessed in 2025 and the correct examination session.
  • Ask which optional theme or themes the school will teach.
  • Identify the prescribed text and study its arguments, not merely famous quotations.
  • Practise the Being human core through precise questions about identity, freedom and nature.
  • Prepare Paper 1 stimulus-based analysis and theme essays separately.
  • Practise both parts of Paper 2 using the selected text and a clean permitted copy.
  • For HL, practise unseen-text analysis and reflection on philosophical activity for Paper 3.
  • Choose a genuinely non-philosophical stimulus with a defensible philosophical issue for the IA.
  • Keep the IA within 2,000 words, references and stimulus exclusions, and maintain authentic work.
  • Use discussion to test arguments fairly, including objections that challenge the student’s preferred view.
