I'm not worrying about my Irish past. What has my Celtic blood ever done for me but give me a restless and unstable mind that gives me no rest in anything I do? Damn the Shan Van Vocht, and the ancestors that went to Sassenach gallows for her, and damn the Irish and damn the black Milesian blood in my veins that makes me like drift-wood fighting the waves and gives me no peace or rest waking or sleeping or riding or dreaming or traveling or wooing, drunken or sober, with hunger or slumber on me.

From a letter to Harold Preece (1929)
