Knowledge questions (KQs) form the heart of the TOK course, and provide us with the opportunity to discuss, explore, and sometimes argue about the way in which we acquire, use, and evaluate our knowledge about the world. Good KQs should be about how we know about the world, rather than what we know about the world (in other words, second-order knowledge, rather than first-order knowledge), which is what distinguishes TOK from the other DP courses. Sometimes the difference between these types of knowledge is difficult to distinguish, but you’ll get better at it with practice, as you progress through the course. The KQs below relate to our fourth Big Question for the human sciences, ‘Perspectives’. Note that many of them link to other themes, areas of knowledge, and BQs, so one of the first things you could consider is how they relate to, and impact on, other aspects of the course.
