In Peter S. Beagle's "The Last Unicorn," the statement reflects a profound philosophical idea about memory and existence. It suggests that forgetting something not only removes it from our consciousness but also implies that it lacked true significance or reality in the first place. This perspective raises questions about the nature of existence and how closely tied our memories are to the realities we perceive.

This quote emphasizes the importance of memory in defining what is meaningful in our lives. If we fail to remember or acknowledge something, it may as well not have existed at all. This insight invites readers to consider how our experiences shape our understanding of reality and the transient nature of existence itself.
