From the NYT article Masters of the Form

The Liberal Imaginiation “The job of criticism would seem to be, then, to recall liberalism to its first essential imagination of variousness and possibility, which implies the awareness of complexity and difficulty. To the carrying out of the job of criticizing the liberal imagination, literature has a unique relevance, not merely because so much of modern literature has explicitly directed itself upon politics, but more importantly because literature is the human activity that takes the fullest and most precise account of variousness, possibility, complexity and difficulty.” — LIONEL TRILLING 1950
