"I know that every good and excellent thing in the world stands moment by moment on the razor-edge of danger and must be fought for"

In this quote, Thornton Wilder is highlighting the fragility and vulnerability of all things that are great and excellent worldwide. He suggests that these things are constantly at threat and must be actively secured and protected. Using the expression "razor-edge of threat" communicates a sense of imminent danger and the need for constant watchfulness. Wilder's words serve as a tip that nothing of value comes easily which we should be willing to eliminate for what we believe in and what we love. This quote acts as a call to action, prompting us to actively work towards preserving and promoting the great and outstanding things in our world.
