Diversity and Morality

What is Morality?



Is the definition of good and evil something arbitrarily determined by someone?

Does morality vary along with areas, cultures, and eras?

Does morality, after all, have any common principle?

Do studies of morality, such as moral philosophy and ethics, end up in mere descriptions of different, miscellaneous moral systems?

If your child questions like "Can homicide be condoned in capital punishment?", can you provide a proper and sufficient answer as a parent?



Ung-il Chung, M.D., Ph.D., Professor of Department of Bioengineering at University of Tokyo Graduate Schools of Engineering and Medicine, offers the solutions with scientific and logical way as follows :



1. Presentation of Problems: Analyzing the Current Status of Morality

2. Previous Studies: Studying Prior Moral Thoughts

3. Construction of Models: Modeling the Basic Principles of Morality

4. Development of Applications 1: Do Animals Have "Morality"?

5. Development of Applications 2: Relationship between Morality and Language

6. Simulations and Prediction: How Should We Live?

Professor, Department of Bioengineering, Graduate Schools of Engineering and Medicine, The University of Tokyo, Tokyo, Japan



Dr. Chung graduated from University of Tokyo School of Medicine to obtain M.D. in 1989. After working as a Resident and Clinical Fellow in Internal Medicine at University of Tokyo Hospital, he entered and graduated from University of Tokyo Graduate School of Medicine to obtain Ph.D. in 1997. In 1998, he was appointed Instructor in Medicine, Harvard Medical School, and then in 2001 Assistant Professor of Medicine. In 2002, he came back to his alma mater, worked at Graduate Schools of Medicine and Engineering. Since 2007, he is holding his current position. He attempts to clarify the mechanism and origin of morality and to create devices to measure and visualize morality levels using voice recognition system. He also tries to install the morality engine on artificial intelligence and robots.
