What does Ralph Waldo Emerson mean by science not know its debt to imagination?

Ralph Waldo Emerson means that science does not sufficiently acknowledge or recognize its reliance on imagination. He believes that science often presents itself as a purely objective and rational endeavor, but in reality, it is also influenced by creative thinking and intuitive leaps. For Emerson, imagination is essential for the development of scientific knowledge, as it allows scientists to envision new possibilities and make connections between seemingly unrelated phenomena.
