The word "facts" is, in some ways, crucial. 
I have spoken with Jesuits and Plymouth Brethren, mathematicians and poets, dogmatic republicans and dear old gentlemen in bird's-eye neckcloths; and each understood the word "facts" in an occult sense of his own... We had each of us some whimsy in the brain, which we believed more than anything else, and which discolored all experience to its own shade. How would you have people agree, when one is deaf and the other blind? R.L.Stevenson.
