The article author speculates whether the number of ideas is finite. A 1994 International Bioethics Survey asked nearly 6000 people in 10 countries 150 questions on bioethics dilemmas. From its results, the author had proposed that the number of human ideas is finite. The evidence continues to suggest that the number of ideas is finite, and thus countable. The project aims to compare mental maps and idea diversity between individuals and species in order to develop descriptive bioethics into a common framework for comparative ethics. The map will aid policy making that respects diversity of people within a culture and globally. Guidelines should be culturally sensitive regarding ethical, social, and legal aspects.
