Heinlein also writes:
Piling up facts is not science--science is facts-and-theories. Facts alone have limited use and lack meaning; a valid theory organizes them into far greater usefulness. ... A powerful theory not only embraces old facts and new but also discloses unsuspected facts.
It's easy to downplay the importance of facts when the vast majority of people base their conclusions about facts on actual, real world evidence. However, when a not inconsequential number of people are unable to accurately perceive reality or come to accurate conclusions about facts, it's impossible to overstate the importance of facts.
