The document discusses remembering lessons from the past and how the past influences the present and future. It provides examples of how schools were different in the past compared to now, such as students sharing desks that were bolted to the floor, using oil lanterns for lighting, and dipping quill pens in ink rather than using modern pens and lights. The key lessons are that remembering what was learned in the past is important, the past affects the future, and schools have changed over time.
