Essential Thinkers

Here’s a (far from comprehensive) list of TOK thinkers who could play a starring role in the course. Although many of the names will be familiar, there are some less well known figures as well. But as the description of each person’s key idea or ideas should make clear, everyone on the list can provide the basis for at least one effective TOK lesson - and most for significantly more than that.

Note that there are many other thinkers who could have made the list; we’ve included these thinkers because considered together they help students to understand a wide range of ideas, from the natural sciences to the arts; from technology to religion; from history to mathematics.
