"...Vellacott's sympathy for the man and for pacifism has not led her to exaggerate the importance of his wartime activities. Nor does she fail to see that these years did not begin or end Russell's emotional and intellectual growth. Yet, for him, the Great War was a watershed; he emerged from it changed in both head and heart. Vellacott demonstrates that Russell's involvement with the pacifists was essential to that metamorphosis."
