Denning's Law states that "the more you know, the more you realize you don't know." This principle highlights the idea that as individuals gain knowledge in a particular field, they become aware of the vastness of what remains unknown. This realization can lead to a deeper appreciation for the complexity of the subject matter. The law is often associated with the field of education and learning, emphasizing the importance of continuous inquiry and exploration. It encourages a mindset of curiosity, suggesting that true understanding comes from recognizing the limits of one's knowledge and seeking to expand it further.
