In Ian McEwan's novel "Solar," the protagonist reflects on the cyclical nature of life and the lessons learned from prior experiences. He recognizes that past events have often indicated that time can resolve issues and bring clarity to difficult situations. This realization highlights a sense of hopefulness towards the future, suggesting that one can find solutions in the progression of time.

The quote emphasizes an important philosophical perspective: the idea that while challenges and uncertainties may arise, they can be addressed as time unfolds. It serves as a reminder that the path ahead is shaped by previous experiences, and trust in the future can lead to personal growth and understanding.
