Kathavatthu (Pali), literally "Points of Controversy", is one of the seven books in the Abhidhamma Pitaka. This work was compiled by the venerable Moggaliputta Tissa, who presided over the Third Council, in order to clarify the points of controversy regarding Dhamma, that have arise between the various Nikaya Buddhism Schools. There are 23 chapters dealing with some 216 controversies in the form of dialogues in a logical method. Each chapter contains questions and answers by means of which the most diverse false views are presented, refuted and rejected.
