Throwback: Protagoras

I came across this book on Amazon.com last night.Looking at it after studying Protagoras, its interesting to me that a book exists to teach parents how to teach their children virtues. Protagoras' belief that virtue must be taught in order to compensate for the relativity of justice and value is very present in today's society, as evidenced by this book. Its interesting that not only do we need to teach our children values, but we must first be taught how to teach them. It also got me thinking about the attitude each generation has towards the generations that come after. It seems that as people age, they adopt a "when I was your age" mentality towards those younger than them.Many people seem to view the generations below them as less moral or more resistant to the solid values of the good ol' days. Does this mean we are getting worse at teaching virtue? Are virtues becoming increasingly relative? Or, are virtues changing at a pace that prohibits them from being passed down to subsequent generations?
