Famous quotes containing the words unique and/or visitor:
“When the object is perceived as particular and unique and not merely the member of a family, when it appears independent of any general notion and detached from the sanity of a cause, isolated and inexplicable in the light of ignorance, then and only then may it be a source of enchantment.”
—Samuel Beckett (1906–1989)
“In verity ... we are the poor. This humanity we would claim for ourselves is the legacy, not only of the Enlightenment, but of the thousands and thousands of European peasants and poor townspeople who came here bringing their humanity and their sufferings with them. It is the absence of a stable upper class that is responsible for much of the vulgarity of the American scene. Should we blush before the visitor for this deficiency?”
—Mary McCarthy (1912–1989)
