Famous quotes containing the words universal and/or joint:
“The universal social pressure upon women to be all alike, and do all the same things, and to be content with identical restrictions, has resulted not only in terrible suffering in the lives of exceptional women, but also in the loss of unmeasured feminine values in special gifts. The Drama of the Woman of Genius has too often been a tragedy of misshapen and perverted power.”
—Anna Garlin Spencer (1851–1931)
“I learned from the git-go in the joint to get in touch with the soft, nurturing side of myself, the feminine side.”
—Wesley Strick, U.S. screenwriter, and Martin Scorsese. Max Cady (Robert DeNiro)
