UFOs and the Western Mind | Dr. John E. Mack [1]

the one unforgivable sin to the western mind is when something that should be in the spirit world, transgresses and shows up in the physical world. That traffic is the cardinal sin for the western mind. So it has great power to shatter the belief structure of the western mind when that occurs. And that's precisely what's occurring (with the UFO phenomenon)."
