What we know depends on our point in history and our place in a particular society and culture. Showing that you can consider and explore different perspectives and viewpoints to knowledge questions is a requirement in TOK assessment tasks.
Thinking about a knowledge question from different cultural perspectives is one way of showing that your own viewpoint is one of many. An alternative approach is to consider the view of a different point in history. You might explore the contribution of key thinkers and the impact they have had on knowledge and knowing.
