So it doesn't really go about trying to disprove the existence of evil spirits per se---BUT it has falsified that evil spirits are responsible for occurances in the natural world. For instance, at one time they were blamed for illness, failed crops, still births, visions, mental
illness etc. Science has disproven that evil spirits are behind this by actually finding the causes.
Okay, not that I think evil spirits are floating around causing crops to fail and babies to be still-born... but for argument's sake... having another possibility, even having something else replicate the same results, does not actually falsify something, right? A crop could fail for multiple reasons... one reason does not falsify another. But if someone said that crops fail only because of drought... then that would be falsifiable because crops have been observed to fail because of pests, as well, and whatever else. And if someone said that crops fail because of evil spirits... well, that can't be falsified, so it can't even be a scientific hypothesis until such a time as it can be falsifiable.
I do understand that science is in the business of reporting on what it physically observes... and spirits would not be among such things.
tec, try thinking of it this way: the statement must be falsifi-ABLE. It must be -able- to be falsified.
No, I hear you. Unless there is some way/test/situation that a statement could be proven/observed to be false, then it stays out of the realm of scientific hypothesis and theory.
