Famous quotes containing the word challenges:
“The approval of the public is to be avoided like the plague. It is absolutely essential to keep the public from entering if one wishes to avoid confusion. I must add that the public must be kept panting in expectation at the gate by a system of challenges and provocations.”
—André Breton (1896–1966)
“A powerful idea communicates some of its strength to him who challenges it.”
—Marcel Proust (1871–1922)
