Imagine that you are standing in a small clearing in the middle of a vast forest, and that this forest represents your ignorance of the world. The clearing you stand in represents your knowledge. As one gains knowledge, the clearing expands and the forest of ignorance recedes. But as the clearing expands, so does its circumference and so the area of contact between knowledge and ignorance also grows, and our knowledge of the extent of our ignorance grows with it. So, paradoxically, the wiser we become, the less wise we feel. This is the wellspring of intellectual humility, the Socratic realization that the more you know, the more you realize you don’t know, and the more apparent it becomes that your own opinions are susceptible to fallibility.
