Famous quotes containing the words function and/or library:
“Morality and its victim, the mother—what a terrible picture! Is there indeed anything more terrible, more criminal, than our glorified sacred function of motherhood?”

Howbeit eluding fallopian diagnosis,
She simpers into the tribal library and reads
That Keats died of tuberculosis . . .”
