The quote from Miguel de Cervantes Saavedra's "Don Quixote" highlights the different ways people engage with knowledge and experiences at various stages of life. Children are portrayed as being in a phase of discovery, where they interact freely and playfully. Young people are depicted as observers who absorb information through reading, expanding their understanding of the world around them.

As individuals transition into adulthood, they begin to comprehend and analyze the complexities of their experiences, reflecting a deeper understanding of life. Finally, the elderly are shown as those who celebrate and find beauty in their memories and contributions, elevating their past to a revered status. This progression illustrates the evolving relationship individuals have with knowledge and life as they age.
