Justice

I'm reading a book named "Justice" written by Michael Sandel. This book was written from basis  of lecture of Harvard. What is right thing to do? This is conundrum. But this complex problem was thought by many people on our history. Aristoteles, J.S. Mil, Bentham... and, us. Sandel said, to think about this conundrum is reason of citizen being. We have to, and are able to think this problem in our everyday life. This is live wisdom as same as other wisdom.
