 All information technologies record (store), transmit (communicate), organize and/or synthesize information. For example, a book is a record of information, a telephone is used to communicate information, and the Dewey decimal system organizes information. Many information technologies can accomplish more than one of the above functions and, most notably, the computer can accomplish all of them since it can be described as a universal machine (see the entry on  computability and complexity),  so it can be programmed to emulate any form of information technology. In  section 2  we will look at some specific example technologies and applications from each of the three types of information technology listed above and track the moral challenges that arise out of the use and design of these particular technologies. In addition to the above we will need to address the growing use of information environments such as massive multiplayer games, which are environments completely composed of information where people can develop alternate lives filled with various forms of social activities (see  section 3.3).  Finally we will look at not only how information technology impacts our moral intuitions but also how it might be changing the very nature of moral reasoning. In  section 4,  we will look at information as a technology of morality and how we might program applications and robots to interact with us in a more morally acceptable manner.
