Abstract
In this article, I begin by saying something about what metacognition is and why it is desirable within education. I then outline how Plato anticipates this concept in his dialogue Meno. This is not just a historical point; by dividing the cognitive self into a three-in-one—a ‘learner’, a ‘teacher’ and an ‘evaluator’—Plato affords us a neat metaphorical framework for understanding metacognition that, I contend, is valuable today. In addition to aiding our understanding of this concept, Plato’s model of metacognition not only provides us with a practical, pedagogical method for developing a metacognitive attitude, but also for doing so through doing philosophy. I conclude by making a case for philosophy’s inclusion in our school systems by appeal to those aspects of philosophy that are metacognitive or that are conducive to developing metacognition, as revealed by the insights afforded us by Plato’s Meno and Theaetetus.
