Greetings, Moreno
You ask, “How will your system avoid the problem of contradicting religions and other secular moral systems? Won’t it simply be another voice disagreeing (and agreeing where it does)?”
If you had read the Preface to Katz & Harvey - LIVING THE GOOD LIFE, you would have gained insight into the larger vision - which is to make Ethics into a science.
Science is not “just another voice” for when it leads to relevant technologies it produces results, which often turn out to have worthwhile benefits. Sure, the results may have downsides, and we can depend upon Philosophers-of-Ethics to find them, just as now such critics always seek out the exceptions to any general principle one might propose - exceptions that test ‘the rule.’
My impression of the Dalai Lama is that he laughs easily and frequently, and writes books on moral philosophy. I have heard him on panels, on CSpan TV, and he was not that dull to listen to; but I never heard him lecture, and I doubt I would want to suffer through one - but I could say that about many another lecturer too. I have heard a fellow they called Rinpoche speak, but he was very concise, and seemed to be a man of few words. What he did utter was very pointed and appropriate however. I venture to speculate that the Dalai Lama is a motivational speaker for Buddhist monks, as well as for Buddhist disciples here in America; but I will grant he is not that for the rest of us.
I see no reason what a good person has to be boring. Some good people are inspiring. Some are charismatic.
And one can always play the game of “what if” and find “deeper problems” in that mind game, in that hypothetical world. I myself happen to be quite adept at dreaming up worst-case scenarios, but it doesn’t help me to win friends and influence people. I prefer being an Optimist, a thoughtful rational optimist. I want to be mindful. I want to be aware. In that booklet, LIVING THE GOOD LIFE, there is a chapter on the difference between optimists, pessimists and realists. The latter turn out to be part-optimist, as the analysis shows.
This current thread’s o.p. ought to be read in conjunction with earlier threads such as “The Beautiful Simplicity of Ethical Concepts” and/or “Steps to Value Creation.” That procedure would aid in comprehending the big picture.
