[Coleman] points out that Adam and Eve must have already had some capacity to make good or bad decisions, else the snake's offer would be futile. Sin, then, is the deliberate transgressing of boundaries set for us…As we make the world in our own image with the tools of science, Coleman holds that we have a duty to individually and corporately guard these limits. My summary cannot do justice to his profound argument, so I would recommend this book to anyone who desires to better understand that duty.
