“The most beautiful experience we can have is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science.”
This quote stems from a short story I’ve read several times called The Power of Mysteries by Alan Lightman (an astrophysicist). The man has also written Einstein’s Dreams and A Sense of the Mysterious: Science and the Human Spirit.
He references the above quote to show that mystery is not all about the unpredictable, supernatural forces, or the unknown. It is meant to show that mystery shows us that there are things larger than us, that we do not have all the answers at this moment. “A sense that we can stand right at the boundary between known and unknown and gaze into that cavern and be exhilarated rather than frightened.”
