The fundamental task of education is not to instill knowledge, but to cultivate the "habit of thinking." In an age of information explosion, teaching children to question and discern is more important than having them memorize facts. "Knowledge" is static, accumulative information, while "the habit of thinking" is a dynamic, generative ability. The former is like goods in a warehouse, and the latter is the tool to navigate those goods; the former can be measured in standardized ways (such as exam scores), while the latter manifests as an individual's mental vitality.
