Famous quotes containing the word boundaries:
“Women’s art, though created in solitude, wells up out of community. There is, clearly, both enormous hunger for the work thus being diffused, and an explosion of creative energy, bursting through the coercive choicelessness of the system on whose boundaries we are working.”
—Adrienne Rich (b. 1929)
“We love to overlook the boundaries which we do not wish to pass.”
—Samuel Johnson (1709–1784)
“The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?”
—Edgar Allan Poe (1809–1845)
