Hi Genesis,
As I said in the OP, I no longer subscribe to “live and let live” with regard to domgatic belief. I completely agree that some dogmas are more dangerous than others, and even that belief in certain dogmas can make people behave well (though this would not constitute evidence that such dogmas any more true). But the problem with dogma in general is that it gives us no way to argue that one is true and another is false since by definition dogmatic beliefs are not based on evidence. People who hold beliefs that are subject to the usual standards of evidence and arguments in the pressure of conversation have some hope of coming to agreement, while those who simply claim that they possess revealed truth have no recourse to dialogue with those who claim to possess a contradictory revealed truth. (They do, as history has shown, have a recourse to violence.)
Consider what it is like when we really understand something? Such knowledge transcends nationalism and religious divisions. there is no Jewish algebra as opposed to Muslim algebra or Christian biochemistry or Hindu physics. Why? Because such knowledge is not thought to be revealed truth but rather truth about what happened throusands of years ago but rather truth that is available to anyone right now and subject to revision as new evidence and arguments become available.
Best,
Leela
Believing something by faith is not the same as believing it for no reason. It’s a mistake to say the usual modes of evidence don’t apply. There are a great many events in human history that we believe happened but which we did not personally witness. We know them by the testimony of people who did witness them and by those who have handed on that witness. The evidence we have is the testimony and we judge it based on the credibility of those testifying to it (and those handing on that testimony through the decades and centuries). The Incarnation, or any other alleged event of divine revelation, is posited as a real event in human history and can be judged and known as such. You believe what you do about the history of religious violence because you trust the people who have testified to this information. For another example, all court cases are judged based on testimony alone–even the physical evidence has to be authenticated by testimony. Jurors never see the event for themselves (even if there is video of it, the video must be authenticated by testimony).
Likewise, even the truths you mention weren’t originally universally known. As you said, there has been erroneous understandings of different natural processes and even different mathematical systems in different cultures. But over time, through human persuasion, those cultures with erroneous beliefs in those areas adopted the true ones. Even algebra was not universally known at one time.
It is no different with religion. Historically we can see this happening as the unreasonable worship of man-made items (stone idols, mythical contingent beings, etc.) being exchanged for worship of a non-contingent Creator almost completely.
However, even to this day, in any sphere of truths, people believe things contrary to reality–by innocent ignorance, by obstinance, for convenience, due to habit, negligence, etc. However, the truth can be known–including the truth about God.
People have resorted to violence (as individuals and as groups and societies) for a great many pretexts. 99% of the time it is over resources (land, money, authority, etc.). People also commit violence against those of a different race. Why? I have no idea (someone else can probably explain this phenomenon better) but skin color can’t be called the cause of the violence just like a set of religious doctrines cannot be called the cause of the violence (unless the doctrine exhorts the follower to violence–and then we can look at the origin of that doctrine, the possible motive of the one claiming its veracity–is it to preserve or gain power, to manufacture peace and order, etc., solely the good of others, etc?–and judge his credibility.).
People will do violence no matter what–they are fallen. Look at homogenous societies (at least as homogenous as possible) and there is still murders, robberies, gang violence, etc. The only solution is the healing of that fallenness. All superficial attempts at peace are bound to fail.
