Bishop Gerald Kennedy tells this story:

The late Bishop Francis J. McConnell was once president of DePauw University. He always liked to be on the land, and after retirement he lived on a farm in Ohio. When he was at DePauw he had a small acreage where he raised chickens. He said that everything went all right except in the middle of the night the rooster would start to crow and wake everybody up. He could not understand the behavior, so he stayed up one night to find out the trouble. He said that along about two o'clock in the morning, the interurban train coming out from Indianapolis would swing around a curve, and the headlight would shine into the chicken house. The rooster, thinking it was the sun, would begin to crow. And the bishop said, "It is not only roosters that mistake headlights for dawns."

Indeed it is not! If men can sometimes bring the darkness, so sometimes in their pride and in their limited knowledge they can promise dawns which never come, and bring disillusionment.
