Famous quotes containing the words current and/or symbols:

“Men perceive that equating love and domestic work is a trap. They fear that to get involved with housework would send them hurtling into the bottomless pit of self-sacrifice that is women’s current caring roles.”
—Debbie Taylor (20th century)

“As usual I finish the day before the sea, sumptuous this evening beneath the moon, which writes Arab symbols with phosphorescent streaks on the slow swells. There is no end to the sky and the waters. How well they accompany sadness!”
—Albert Camus (1913–1960)
