De Lubac's book is a masterpiece of intellectual
erudition and sophisticated apologetics that argues that the
deepest human longings for unity — longings that made communism so alluring to many idealistic people in the first half of the twentieth century — are fulfilled in the Church's supernatural mission.
Yet for all his learning and
erudition, Motherwell's greatest works have an astounding visual potency, a harnessing of spontaneity and introspection, that enabled him to engage with his
deepest, innermost feelings.
