One reason why I think reading great books multiple times is important is that it allows us to gain new insights and perspectives on the text each time we read it. Our understanding of a book can change as we grow and experience new things in life, and rereading a book can help us see it in a new light. For example, a book that might have seemed simplistic or shallow on our first read-through might reveal itself to be a deeply complex and thought-provoking work on a second or third read. Additionally, rereading a book can help us better understand and appreciate the author's intentions and the themes and ideas they were exploring.
