‘Roots’ recounts Clive Staples Lewis’s early life in a close-knit Christian family—his parents, Albert and Flora, and his brother, Warren—in County Down, Northern Ireland. His atheism was probably triggered by his mother’s death when he was not quite ten. His early schooling was much improved by his private tutor, William T. Kirkpatrick, who added dialectical precision to the rhetorical and argumentative disposition Lewis inherited from Albert. The impact of George MacDonald’s Phantastes on Lewis is highlighted, along with his service in World War I; his time as an undergraduate at Keble College, Oxford; his election to a fellowship at Magdalen College; his diary writing; and his conversion to Christianity.
