Short story of a day

We can live only in relationships. We need each other. A rather crude and cruel experiment was carried out by Emperor Frederick, who ruled the Roman Empire in the thirteenth century. He wanted to know what man's original language was: Hebrew, Greek, or Latin? He decided to isolate a few infants from the sound of the human voice. He reasoned that they would eventually speak the natural tongue of man. Wet nurses who were sworn to absolute silence were obtained, and though it was difficult for them, they abided by the rule. The infants never heard a word -- not a sound from a human voice. Within several months they were all dead.
