Chatuskoti (Catuskoti - Tetralemma - චතුස්‍‍තෝටිකය) is a logic system that existed in ancient India and Sri Lanka. It can be called the logic of Buddhism. It is more like an extension to the modern Binary logic. You may download the presentation to view the Sinhala text (if you have Sinhala unicode installed).
