I'm afraid I have to disagree on both counts. I think the metaphysical systems of the Great Traditions speak for themselves in that regard. They don't need me to champion them.
The great diversity of the claims world wide systems of Great traditions do in fact speak for themselves in great diversity and contradictions.
As I said, I regard the essence of religion as transcending time and place, although obviously are expressed in time and place ... the art is to see through the veils.
The problem is the 'art to see through the veils' remains to variable with a huge diversity of claims and anecdotal, to stand the more objective unbiased claims of the huge diversity and contradictory claims.
Here I go again 'Yes, love and compassion as well as the Golden Rule are universal, and remain at the heart of the spiritual human nature.'
Oh, they are. I could direct you to ancient texts that do just that. Indeed, Paul Ricoeur offers a commentary on man – his Time and Narrative – that is founded in and on Aristotle and Augustine. I'm sure the same insights are there in the commentaries of the Great Traditions.
I agree that there are 'some' insights in the commentaries of the Great Traditions of ALL the religions of the world, but I could not take the views of Aristotle and Augustine as remotely definitive and exceptional above the diverse others in the different traditions of ALL the religions.
Where there is fault, it's man, not the religion. Faced with the current migrant crisis in Europe, I see precious little evidence of a humanity becoming one. I think this stands to be a chimera of the late 20thC. The leading nations have shown no inclination to regard the world as one ...
The unfortunate fallible human view of the rejection of the inherent unity of humanity is indeed a human view, and not the spiritual teaching from God. Humans are the ones that make up religions.
What the 20thC demonstrates is a propensity to violence that has nothing to do with religious affiliation, therefore religion in itself is not the source of the problem.
The evidence is clear that much of the violence in history and today is due to religion. The current violence and wars in the Middle East is definitely a religious conflict going back thousands of years.
I do put them in their cultural context, but I can also see their universal aspects. Also that there is nothing 'new' that cannot be found to be in the Great Traditions' texts and commentaries.
(I tend to think the 'spiritual evolution of humanity' is a 20th century invention, largely syncretic, largely artificial, and fundamentally political – it's a linear reading of history which is increasingly being shown by science to be not quite accurate.)
I can't think of any spiritual doctrine that is not present in the ancient traditions. Rather, most if not all contemporary spiritual teachings take from the ancient traditions.
It is anecdotal to claim 'most' or even 'some' if not all contemporary spiritual teachings take from ancient traditions is inadequate to define what is true and what is not. Again considering the religions of the world as a whole it remains that the claims are too diverse, anecdotal and contradictory to make definitive judgments to claim the validity of one religon or belief system over another.
Illusive anecdotal theist claims are not subject to proofs that are not circular.
To clarify:
My use of the word 'scientism' refers to those who erroneously believe that science will explain away religion. The contrary is those who evidence the worst cases of religious intolerance, bigotry etc,. as if that invalidates religion. This is a nonsense, but it's one of the most-often deployed arguments by atheists today. I get it all the time.
What you 'claim to get all the time,' and the
philosophical claims of atheists, is not science. It is the philosophical assertions and claims of some scientists, and popular media. Your rant does not make it clear you understand the difference between real 'Methodological Naturalism,' which are the methods of all scientists, including atheists, and their philosophical views. It would be difficult for you to falsify or find fault with the actual peer reviewed published scientific work of the most radical atheists, like Dawkins nor other atheist/agnostic scientists like Einstein, who make anecdotal philosophical claims of atheism/agnosticism.
Good science of course does no such thing. It stays within its stated axioms. My 'unfortunate view' is not at all related to ancient world views, but to the ill-informed or assumptive arguments I hear on a regular basis. They're as evident today as ever they were. I am not against science, as long as it recognises its sphere of activity. Indeed, as there are some outstanding scientists who hold religious beliefs, so the whole science v religion thing is a nonsense. 'Scientism' is equivalent to religious fundamentalism.
You have failed to define nor adequately describe what you consider as 'good science,' since your claims of 'Scientism,' is not really science at all, but philosophical claims by some scientists. You use of 'scientism' remains a vague anecdotal concept, and your real objection is to the philosophical beliefs of Ontological Naturalism and not science at all.
Please be more specific as to how you define and/or describe good science.
