Western "science" has given some people a sense of power over the environment. Some believe that all we need to do is splice a few genes here and there and we can build ourselves a Utopia, free of pests. Medical technology has "progressed" to the point where there are pills and operations for just about every ailment known.
Little homage is given anymore to the notion that all of life is connected, and that whatever we do somewhere has an effect everywhere else. We have so bought into the "religion" of science that we now go to great lengths to suppress alternative views. The idea that most/all "this-ease" is born in the mind and can be cured by changing one's mind is not given any credence. Once upon a time, science meant investigating anomalies, for they are the key to deeper understanding. Now, it means ignoring them as a fluke, bad data, or worse. The Inquisition is still in full force.
Science can't answer questions about value. For example, there is no scientific answer to the questions, "Which of these flowers is prettier?" or "which smells worse, a skunk or a skunk cabbage?" And of course, there's the more obvious example, "Which is more valuable, one ounce of gold or one ounce of steel?" Our culture places value on the element gold, but if what you need is something to build a skyscraper with, gold, a very soft metal, is pretty useless. So there's no way to scientifically determine value.
Science can't answer questions of morality. The problem of deciding good and bad, right and wrong, is outside the determination of science. This is why expert scientific witnesses can never help us solve the dispute over abortion: All a scientist can tell you is what is going on as a fetus develops; the question of whether it is right or wrong to terminate those events is determined by cultural and social rules--in other words, morality. The science can't help here.
The first and most fundamental thing to be remembered is that enlightenment can never have a technology. By its very nature it is impossible. But the west is obsessed with technology, so whatsoever comes into the hands of the west, it starts reducing it into a technology. Technology is an obsession. For the outside world, science is a valid approach, but partial, not total; not the only approach, but only one of the approaches. Poetry is as valid as science.
but there is a code of ethics that is to follow....
As to your idea of change ones mind... No matter how much you change your mind it isn't going to kill that virus cell in your body and cure you. Sorry, ain't going to happen.
