Famous quotes containing the words advanced and/or research:
“A free-enterprise economy depends only on markets, and according to the most advanced mathematical macroeconomic theory, markets depend only on moods: specifically, the mood of the men in the pinstripes, also known as the Boys on the Street. When the Boys are in a good mood, the market thrives; when they get scared or sullen, it is time for each one of us to look into the retail apple business.”
—Barbara Ehrenreich (b. 1941)
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?””
—Sigmund Freud (1856–1939)
