Famous quotes containing the words large and/or systems:
“Every society consists of men in the process of developing from children into parents. To assure continuity of tradition, society must early prepare for parenthood in its children; and it must take care of the unavoidable remnants of infantility in its adults. This is a large order, especially since a society needs many beings who can follow, a few who can lead, and some who can do both, alternately or in different areas of life.”
—Erik H. Erikson (1904–1994)
“In all systems of theology the devil figures as a male person.... Yes, it is women who keep the church going.”
—Don Marquis (1878–1937)
