As you gained more knowledge, you formulated more questions. You sought answers which led to more questions. The more questions you answered, the more knowledge you gained which in turned led to more questions. The more you learned, the less you knew.
Or so it seemed.
The reality is that the more you learned, the more you realized that there was more to learn. You began to understand that the more you knew about the subject the easier it was to formulate questions. Those questions allowed you to seek answers and the cycle of learning continued.
“To know, is to know that you know nothing. That is the meaning of true knowledge.” — Socrates
