Food for thought
I just finished reading a book called Irreligion by John Allen Paulos. One of the passages near the end caught my attention and I thought I'd quote it here.
"Still, people do often vigorously insist that religious beliefs are necessary to ensure moral behavior. Though the claim is quite clearly false of people in general, there is a sense in which it might be true if one has been brought up in a very religious environment. A classic experiment on the so-called overjustification effect by the psychologists David Greene, Betty Sternberg, and Mark Lepper is relevant. They exposed fourth- and fifth-grade students to a variety of intriguing mathematical games and measured the time the children played them. They found that the children seemed to possess a good deal of intrinsic interest in the games. The games were fun. After a few days, however, the psychologists began to reward the children for playing; those playing them more had a better chance of winning the prizes offered. The prizes did increase the time the children played the games, but when the prizes were stopped, the children lost almost all interest in the games and rarely played them. The extrinsic rewards had undercut the children's intrinsic interest. Likewise, religious injunctions and rewards promised to children for being good might, if repudiated in later life, drastically reduce the time people spend playing the "being good" game. This is another reason not to base ethics on religious teachings."
