rhetorical techniques to reform society
Social commentary is the act of using rhetorical means to provide commentary on issues in a society. This is often done with the idea of implementing or promoting change by informing the general populace about a given problem and appealing to people's sense of justice. Social commentary can be practiced through all forms of communication, from printed form, to conversations to computerized communication.
Two examples of strong and bitter social commentary are the writings of Jonathan Swift and Martin Luther. Swift exposed and decried the appalling poverty in Ireland at the time, which was viewed as the fault of the British government. Martin Luther decried corruption in the Catholic Church, including what today would be termed pedophilia. Examples of social commentators from the lower social strata are Charles Dickens and Will Rogers.
