Quote by Arthur Conan Doyle
Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.
Summary
This quote emphasizes the finite capacity of the human mind and the concept of forgetting as new knowledge is acquired. It underscores the importance of prioritizing useful information over trivial details. By recognizing that our memory has limitations, we can avoid cluttering our minds with irrelevant facts and focus on retaining and utilizing knowledge that is truly valuable and beneficial.
