George Santayana (1863-1952), Scepticism and Animal Faith
(New York: Charles Scribner's Sons, 1923), p. 77:
There is some danger in pointing out the obvious.
Quick wits, perceiving at once how obvious the obvious
is (though they may never have noticed it before), will
say it is futile and silly to dwell upon it. Pugnacious
people will assume that you mean more than you say,
and are attempting to smuggle in some objectionable
dogma under your truisms. Finally, docile minds,
pleased to think you are delivering an oracle for their
edification, will bow before your plain words as before
some sacred mystery.
