Famous quotes containing the word seesaw:
“Perhaps if the future existed, concretely and individually, as something that could be discerned by a better brain, the past would not be so seductive: its demands would be balanced by those of the future. Persons might then straddle the middle stretch of the seesaw when considering this or that object. It might be fun.”
—Vladimir Nabokov (1899–1977)
