Famous quotes containing the words conversion and/or units:
“The conversion of a savage to Christianity is the conversion of Christianity to savagery.”
—George Bernard Shaw (1856–1950)
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (1873–1947)
