“What one means by integrity, in the case of the novelist, is the conviction that he gives one that this is the truth. Yes, one feels, I should never have thought that this could be so; I have never known people behaving like that. But you have convinced me that so it is, so it happens. One holds every phrase, every scene to the light as one reads—for Nature seems, very oddly, to have provided us with an inner light by which to judge of the novelist’s integrity or disintegrity. Or perhaps it is rather that Nature, in her most irrational mood, has traced in invisible ink on the walls of the mind a premonition which these great artists confirm; a sketch which only needs to be held to the fire of genius to become visible. When one so exposes it and sees it come to life one exclaims in rapture, But this is what I have always felt and known and desired!”
― Virginia Woolf, A Room of One’s Own

“To make a deliberate falsification for personal gain is the last, worst depth to which either scholar or artist can descend in work or life.

(Letter to Muriel St. Clare Byrne, 8 September 1935)”

“It seems to me a fundamental dishonesty, and a fundamental treachery to intellectual integrity to hold a belief because you think it's useful and not because you think it's true.”
― Bertrand Russell

“Our government, National and State, must be freed from the sinister influence or control of special interests. Exactly as the special interests of cotton and slavery threatened our political integrity before the Civil War, so now the great special business interests too often control and corrupt the men and methods of government for their own profit. We must drive the special interests out of politics.”
― Theodore Roosevelt
