Answer:
In "Maus I" by Art Spiegelman, a quote that emphasizes the theme of the importance of remembering the past to educate the future can be found on page 159. Vladek, the main character, reflects on his experiences during the Holocaust and says, "Friends? Your friends? If you lock them together in a room with no food for a week...then you could see what it is, friends!" This quote underscores the profound impact of the Holocaust on Vladek and the necessity of remembering such events to prevent similar atrocities in the future.
