Morality is about the well being of people and societies in my opinion. Today, western societies are healthier and more literate than any in other century. Social mobility is high and lots of people have plenty of opportunities (although there is always room for improvement). We can think what we want without the threat of punishment. Women and men have an equal opportunity (at least legally) at shaping their life as they see fit. The laws, rules and regulations that lead to well-being, such as education for the young, are the most moral. And well-being, as measured by literacy rate, health and happiness is skyhigh. Higher than any other century. Therefore, this century is the most moral.
The Moral Landscape, by Sam Harris, is a good read on this subject.
We cannot think what we want without threat of punishment and thought policing is becoming more and more prevalent with each passing day. People cannot simply shape life as they see fit: aside from laws and scarcity of resources, lack of education and money both inhibit the ability to shape life. If you look at the education statistics, particularly for the poor, racial minorities and inner city youth, the value of education is tenuous and getting worse. Further, upward mobility is eroding as is social cohesion.
Happiness as an objective measure is, in my opinion, faulty. However, my opinion being worth little in my opinion, I have never seen any other statistically valid measure of happiness from other centuries. In fact, I have never seen a poll of happiness from any century prior to the 20th century (and none from the 20th century before the 50s).
It’s curious how one determines increased morality when considering suicide rates; the increase in divorce rates and abnormal parenting situations (not cohabitating with one’s biological parents) and the corresponding increased risk of drug use and poverty and decrease in attainment of higher education; terrorism; increasing income inequality, et. al. The only way I can rationalize the current state of society as being more moral is that morality is now defined as the ability to make choices.
Would it be correct to consider a person intent on committing homicide as being moral for providing potential victims with a choice of how they want to die: strangulation, poison, gun shot, drowning, etc.? While another potential murderer would be considered even more moral for giving a person the additional option of death by blunt percent trauma to the head?
The value of anything published by Sam Harris is dubious. I have seen him made to look like a complete fool by Eben Alexander, Noam Chomsky, Ben Affleck, William Lane Craig and others. I have also seen him duck debates with both Alexander and Craig. The guy is a pretty classic example of the decline in society: he makes specious arguments, ignores rebuttals and then claims victory by virtue of either being “done” with a discussion or simply by virtue of claiming victory himself. Were Harris a boxer he would have his own belt made and declare himself the world champion of all the world champions.
