This is what Hegel said.

It is said that the ancient Greek philosopher Thales saw the sky full of stars one night and predicted that it would rain tomorrow, but he accidentally fell into a pit at his feet. When someone rescued him, he told the other person this prediction. Thales' prediction became a joke, and philosophers became synonymous with "only focusing on the sky and ignoring reality." Two thousand years later, Hegel used those words of "looking up at the sky" to vindicate the name of philosophers. He even said: "Only those who lie in the pit forever and never look up to the sky will not fall into the pit. ”

Hegel said: A nation can only have hope if it has those people who pay attention to the sky. If a nation only cares about what is happening right now, this nation will have no future.
