“We are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right.”
"In Front of Your Nose" http://www.orwell.ru/library/articles/nose/english/e_nose, Tribune (22 March 1946)
Context: The point is that we are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality, usually on a battlefield.

“We all not only have better intimations, but are capable of better things than we know.”

Context: We all not only have better intimations, but are capable of better things than we know. The pressure of some great emergency would develop in us powers, beyond the worldly bias of our spirits; and Heaven so deals with us, from time to time, as to call forth those better things. There is hardly a family so selfish in the world, but that, if one in it were doomed to die—one, to be selected by the others,—it would be utterly impossible for its members, parents and children, to choose out that victim; but that each would say, "I will die; but I cannot choose." And in how many, if that dire extremity had come, would not one and another step forth, freed from the vile meshes of ordinary selfishness, and say, like the Roman father and son, "Let the blow fall on me!" There are greater and better things in us all, than the world takes account of, or than we take note of; if we would but find them out.
