Thank you for giving us the historical perspective we all should have.
Yes, what you write confirms my view that ethics "are catching on." That is what I have long believed. Slavery and child labor are largely today in ill repute. Women are gradually being recognized as equals when it comes to human rights. The same with gays.Volunteerism in the USA is up and increasing every year. We have more nonprofits devoted to furthering the general welfare than ever before.
We have more foundations dedicated to charitable causes than ever. We have daily-updated internet sites focusing on "the good news" and they do not run out of material for their pages. Etc., etc. Moral intuition is gradually becoming moral practice. I can envision an ethical planet Earth (with a minority of exceptions.) Ethics evolving into a scientific discipline will help the process along as it inspires the creation of more ethical technologies the side-effects of which are to help people become more ethical and stay ethical. I see advancements toward this goal occurring also.
Ethics courses are now an established part of the curriculum in most Business Schools and Colleges, as well in most Law Schools. The time will come when the insights discovered in Moral Psychology and in the new Science of Ethics will penetrate the curriculum of most high schools and colleges.
