We need to be careful about staking the important ethical decisions in our lives on bumper sticker catch phrases. The problem is that the ideas expressed in these bite-sized pronouncements have broader implications.
While the ethical aspect that is explicit in the bumper sticker may look good at first glance, other ideas that follow from it may not be so attractive. Most of us have heard or used the cliché “When in Rome, do as the Romans do,” and it can sound like worthwhile advice. But what if the standard practices of the “Romans” stand in direct conflict with your moral or religious convictions? The is why we need to get behind the cliché’ itself.
Before we commit ourselves to any bumper sticker, we want to make certain that we can accept all that is implied in the slogan.
