Current issues on politics have become so influential in Indonesia that people are divided and become more intolerant of each other. In the age of intolerance it is quite right to rediscover ideas and analyse arguments of the late Gus Dur or KH Abdurrahman Wahid which cement his legacy as an international Islamic figure and a champion of humanity. This paper discusses current theories on arguments and presents practical applications of argumentative devices which are used to analyse Gus Dur’s arguments in his article, Right Islam vs. Wrong Islam which is published in The Wall Street Journal.
