Step-by-step explanation:
Rich Gibson's quote is trying to communicate the idea that life is a journey that moves upward in a spiral pattern, with the past, present, and future all interconnected. The quote suggests that by looking back at the past and understanding the "shadows" or experiences that have shaped our journey, we can more accurately judge the present and make better predictions about the future.
The underlined words "upward in spirals" and "tiny arc up which they climb" refer to the upward movement of life, while the phrase "dim curves of the future above them" suggests that the future is not always clear or easy to predict.
The main theme of the quote is the idea that understanding the past can help us navigate the present and prepare for the future. This theme is connected to the concept of history and the idea that studying the past can give us insight and context for understanding the present and making decisions about the future.
