According to an African fable, four fingers and a thumb lived together on a hand. They were inseparable friends. One day, they noticed a gold ring lying next to them and conspired to take it. The thumb said it would be wrong to steal the ring, but the four fingers called him a self-righteous coward and refused to be his friend. That was just fine with the thumb; he wanted nothing to do with their mischief. This is why, the legend goes, the thumb still stands separate from the other fingers.
