Rational belief

[radames]

I think I'll try to come up with an argument as if I were a theist. I think someone stated that it's necessary to have evidence for a query to be tested and proven true. Prior to the development of the microscope and telescope and stethoscope and x-ray, any guess about the possibility of other worlds, the makeup of the human body, the makeup of other inanimate and animate objects, as well as their functions would have been acceptable or popularized based on how agreeable they were to the masses.

Obviously evolution chose to bring about a higher level of intelligence in us (or maybe inventiveness) as a species so that these inventions could have been pondered and created, regardless of the usefulness of increased intellect. Are we to say that there won't be another device to measure, test, and quantitatively examine, say "belief," "faith," "spirit," among other mysteries? Due to the trend of intellectual development and evolution spanning the last couple of centuries, is it rational to predict a rate of intellectual growth that will bring about a device for measuring what is typically regarded as "delusional, mysterious, unknowable" in today's society? Is this why we are so obsessed with energy these days, to power a device that "looks farther," "looks deeper" for the answers to existence that we crave?
