This thesis is based on the book The Philosophy of Humor and Laughter by John Morreall. In it he starts out by describing the history of the leading theories on humor and laughter which are the superiority theory, relief theory and incongruity theory. Afterwards he gives his own theory. In my thesis I follow the same steps, I dissect the three main theories on humor and laughter, after which I dissect Morreall’s by looking at his reviewers such as Karl Pfeifer. Lastly I attempted to combine everything I learned from the historical theories, Morreall’s theory and his critics’to form my own theory .
