Sometimes I wonder how Dr. Seuss' friends greeted him. Did they say "Hey Seuss!" Would god have gotten mad at them for blasphemy?
Sometimes the Big Questions just don't have any answers.
I have have had a long admiration of his work and my biggest like was the story of the tortoise and hare!
Unless there is another tortoise and hare story that I don't know about, I think perhaps you are thinking of Aesop, who was actually one of my favorite childhood authors. We had a set of "The Book of Knowledge" which was old when I was born, scattered through them were Aesop's fables which I loved looking for when I learned to read. Every one had a "moral" but no religion.
Good question! And what about Dr. Scholl, Dr. Dre, or Dr. Pepper?
Don't forget Dr. Octopus, Dr. Strangelove & Dr. Frankenstein!
