The Dawn of Civilization.

Here's a tale of wisdom. (via European Tribune)

The rabbi put this question to his students: “How can we determine the hour of dawn, when the night ends and the day begins?”
“When from a distance you can distinguish between a dog and a sheep,“ suggested one.
“No,” answered the rabbi.
“When you can distinguish between a fig tree and a grapevine,” offered another. “No.”
“Tell us,” the students said.
The teacher answered, “When you look into the face of a human being and have enough light to recognize in him your brother. Up until then it is night, and darkness is still with us.”
