The International Baccalaureate (IB) Theory of Knowledge essay is a 1200–1600 word essay on prescribed topics or titles created by the IB. As the name suggests, your Theory of Knowledge (TOK) essay should focus on knowledge issues (what is knowledge? why and how do we know things?) and link to other areas of knowledge as well. About two-thirds of your final TOK grade is determined by your score on your TOK essay.

Choosing Your Essay Title

• Mathematics
• Natural sciences
• Human sciences
• Religious knowledge systems
• Indigenous knowledge systems

• “Compare the roles played by reason and imagination in at least two Areas of Knowledge.”
• “When mathematicians, historians and scientists say that they have explained something, are they using the word ‘explain’ in the same way?”

• Do you understand the keywords or concepts in the title? You may not be clear on what a title is asking you to do. Go through the title and highlight any words or concepts you are unsure about. Some titles will use keywords from TOK courses, such as “belief”, “knowledge” “truth”. You may want to check back on your class notes and consider what these words mean in the context of the title.
• Do you have a strong interest in the title? The title should play to your interests and you should feel you can write about the title with care and diligence. For example, if you are skilled or interested in the arts, you may choose a title like “Compare the roles played by reason and imagination in at least two Areas of Knowledge” and pick the arts as one area of knowledge. Keep in mind, however, you should balance your passion for the title with an objective perspective.
• Do you have something relevant to say about the title? It’s important that you relate the question to the ideas you have covered in your TOK course, as well as the topics you have studied in class, and your own personal experiences or thoughts. The essay should have an objective tone, but you will still need to inject it with personality, passion, and clarity.

• For example, in a title like: “When mathematicians, historians and scientists say that they have explained something, are they using the word ‘explain’ in the same way?”, you may rephrase it into two sentences. The title refers to three AOK: mathematics, history, and science. It is then asking you to compare and contrast the way these three AOK use explanation as a way of knowing about a topic or issue.
• By breaking down the title into short sentences, you now have a clearer picture of what the title is asking you to do and how you might go about answering the title sufficiently.

Structuring the Essay

• Understanding the knowledge issues: your essay must be focused on the knowledge issues, link and compare at least two knowledge issues, show relevancy between at least two knowledge issues, and demonstrate a sophisticated understanding of the knowledge issues.
• Knower’s perspective: your essay must demonstrate independent thinking, self-awareness, at least two different perspectives, and several supporting examples.
• Analysis of the knowledge issues: your essay must show insight and depth, justify your main points, present arguments and counter-arguments, and explore any assumptions and implications of your topic.
• Organization of ideas: your essay must be well structured, explain key concepts, be factually accurate, and cite references where applicable.

• You may also be asked “to what extent” or “in what way” a statement is justified. You will then need to present for and against arguments for the statement.
• If you are asked a direct question, your essay should address to what extent or in what ways you are for and against an argument or position.

• Start by doing a general, open brainstorm. Write down everything that comes to mind when you think about the title without passing judgement on any of the ideas, or stopping to read over your brainstorm.
• After five minutes of brainstorming, read over your notes. Identify ideas that relate to each other or that contradict each other. If you are evaluating or assessing a claim in the essay title, create a for column and an against column. Group your brainstorming ideas into either column. Create a third column for grey area ideas, or ambiguities, and place ideas in that column.
• Note any examples of the ideas that you wrote down. For example, you may be addressing a title like: “When mathematicians, historians and scientists say that they have explained something, are they using the word ‘explain’ in the same way?” You may create a brainstorm for each area of knowledge (mathematics, history, science) in relation to the idea of explaining something. You may then use examples of “something” that can be explained in each AOK: a mathematical equation, a historical moment in a battle or a trial, and a scientific theory.

• You should also identify the areas of knowledge you will be discussing in your essay. For example, for a title like: “Compare the roles played by reason and imagination in at least two Areas of Knowledge” you may choose two AOK: the arts and science. You may then compare and contrast the function of “reason” and “imagination” in the arts and in science.

• Paragraph 1: Introduction. You would provide an explanation and interpretation of the title and identify the key terms in the title. You would also state your thesis and explain or identify a knowledge issue related to the title.
• Paragraph 2: First Area of Knowledge. For example, the arts. Discuss how the arts answers the title and provide supporting examples. You should also note any counter-arguments against the title or any limitations of the supporting examples.
• Paragraph 3: Second Area of Knowledge. For example, mathematics. Note how mathematics answers the title and provide supporting examples. You should also note any counter-arguments against the title or any limitations of the supporting examples.
• Paragraph 4: Third Area of Knowledge (if applicable)
• Paragraph 5: Conclusion. Summarize your main ideas and restate your thesis. Conclude by answering the title fully, taking into account the counter arguments and limitations of the areas of knowledge.
• You may also decide to structure your essay based on a main argument and a main counter-argument. Your outline may contain four paragraphs total:
• Paragraph 1: Introduction and explanation of the knowledge issue.
• Paragraph 2: Main argument, with justification and one to two supporting examples.
• Paragraph 3: Main counter-argument, with justification and one to two supporting examples.
• Paragraph 4: Conclusion.

• Some students find it useful to draft their thesis statement once they have finished writing a first draft of the essay. By this point, you will likely have a better sense of the main arguments in the essay and be able to write a clear, concise thesis statement.
• For example, you may need to create a thesis statement for this title: “Compare the roles played by reason and imagination in at least two Areas of Knowledge.” You have chosen two AOK: the arts and mathematics. Consider how reason and imagination function in the arts and in mathematics, as well as the different ways they function in each AOK. Your thesis may be: “Through reason and imagination play an important role in both mathematics and the arts, the imaginative thoughts of mathematicians must be provable, while the imaginative thoughts of artists need only be reasonable.” [5] X Research source

Writing the Essay

• You may want to also refer back to your brainstorming notes to identify the supporting examples for your two areas of knowledge, or your main argument and your main counter-argument.

• For example, you may be discussing the use of reason and imagination in the arts. Rather than discuss a familiar artist, like Picasso, or a familiar example of imaginative thinking, like the Sistine Chapel, use supporting examples that feel original and insightful. Though the essay should be objective in nature, it should also feel reflective and personal. Using a supporting example that you feel passionate about, like Pollack’s kinetic movement paintings, or Rodin’s sculptures, will show you have taken the time to explore unique examples.

• Reference surprising or little known claims, but not well known facts or commonly held opinions. For example: “The sun is the center of the solar system” is a well known fact you will not need to cite. But “Rodin was a traditionally-schooled artist and had a craftsman-like approach to his work” will require a citation as it is maybe a little known fact.
• Reference any sentences or sections where you are closely following someone else’s train of thought or argument, even in your own words.
• Reference exact quotes, and use quotation marks.
• Be consistent with your citations and the way you reference certain sources.

• As you read your essay out loud, make sure there are no vague or abstract sentences or terms. You want to ensure you use your 1600 word count in a clear and concise way. Every word will count in your TOK essay.
• Confirm you have addressed knowledge issues in your essay. Your essay should answer the question “How do you know?” and assess the strengths and weaknesses of knowledge claims in at least two areas of knowledge. You should also use arguments and counter-arguments to support your thesis statement, as well as strong supporting examples.
