Who said “Loneliness is never more cruel than when it is felt in close propinquity with someone…”?

“The surest cure for vanity is loneliness.”

“I was never less alone than when by myself.”

“The eternal quest of the individual human being is to shatter his loneliness.”

“We're all of us sentenced to solitary confinement inside our own skins, for life!”

“What makes loneliness an anguish is not that I have no one to share my burden, but this: I have only my own burden to bear.”

“The management of fertility is one of the most important functions of adulthood.”

“Freedom is fragile and must be protected. To sacrifice it, even as a temporary measure, is to betray it.”

“The surest guide to the correctness of the path that women take is joy in the struggle. Revolution is the festival of the oppressed.”

“The principle of the brotherhood of man is that narcissistic one, for the grounds for that love have always been the assumption that we ought to realize that we are the same the whole world over.”

“The blind conviction that we have to do something about other people's reproductive behavior, and that we may have to do it whether they like it or not, derives from the assumption that the world belongs to us, who have so expertly depleted its resources, rather than to them, who have not.”

“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
