Ideology refers to the important 'belief systems' adhered to by groups or whole societies - it is our 'world view' or 'mind set' concerning how things are and ought to be. A society is a group of people who share certain key values and ideas. These values and ideas are called that society's ideologies. Texts are created by speakers and writers who share society's beliefs concerning 'what is right' and 'what is wrong' or about 'the way things should be for the best' in society.
