The differences between English common law and our current law (both statutory and common law) is amazing, learning about the development, since the law is an ever growing system, is amazing. But the topic is way to large to discuss in a forum such as this. If you are really interested go to a local Law school book store and pick-up Prosser on Torts (its a hornbook) Prosser is considered the Guru on Negligence/Liability.
