From B.H. Liddel Hart's "Why Don't We Learn From History?"
We learn from history that in every age and every clime the majority of people have resented what seems in retrospect to have been purely matter-of-fact comment on their institutions. We learn too that nothing has aided the persistence of falsehood, and the evils resulting from it, more than the unwillingness of good people to admit the truth when it was disturbing to their comfortable assurance. Always the tendency continues to be shocked by natural comment and to hold certain things too “sacred” to think about.
I can conceive of no finer ideal of a man's life than to face life with clear eyes instead of stumbling through it like a blind man, an imbecile, or a drunkard—which, in a thinking sense, is the common preference. How rarely does one meet anyone whose first reaction to anything is to ask “Is it true?” Yet unless that is a man's natural reaction it shows that truth is not uppermost in his mind, and, unless it is, true progress is unlikely.
