Summary
This quote implies that when someone is young, they are full of potential, dreams, and aspirations. They have many theories about life and the world. However, as they grow older and gain more experience, they become more grounded in reality. At that point, they are seen as a fact, as their theories have been tested and their actions have shaped their identity. It signifies the transformation that occurs as one matures, from a theoretical perspective to a more established and concrete existence.
