There are three kinds of people always at work in society: rebels, radicals, and reformers. The rebels are unhappy, angry, and will take any opportunity for mischief and mayhem. The radicals are usually more intelligent and better organized. They may have a social vision that calls for the overthrow of the entire system in order to bring about justice in a certain area. Reformers want to bring needed change to a system with a direction consistent to what the system was originally intended to achieve. Recognize the differences.
