Help me check: a famous saying by Hegel, a great German philosopher: "Only those who lie in the pit forever and don't look up at the sky will not fall into the pit."

It is said that Thales, an ancient Greek philosopher, saw the stars one night and predicted that it would rain tomorrow, but he accidentally fell into the pit under his feet. When someone saved him, he told the other person the prophecy. Thales' prediction became a joke, and philosophers became synonymous with "only paying attention to the sky and ignoring reality". Two thousand years later, Hegel rehabilitated the philosopher with the words of "looking up at the sky". He even said: "Only those who lie in the pit forever and don't look up at the sky will not fall into the pit."

Hegel said: A nation can only have hope if it has people who care about the sky. If a nation only cares about what is under its feet, it has no future.
