That's probably how some people felt after they decreed that Earth, Wind, Fire and Water were the elements, now there's the periodic table. They probably felt the same when Newton's Laws became established, then Einstein came along.
Granted there's higher and lower degrees of certainty, but once you believe in an absolute truth, you've forgone the capacity to take on new evidence. That's dogma.
Take the CERN / OPERA experiment where they thought a particle had travelled faster than light. We suspect this yo be impossible thanks to Einstein, but they didnt just say, "we all know that's impossible", they reexamined the evidence and found out someone dropped a nut. If there hadn't been a mistake, that "rule" would have been smashed and a new one formulated.
