Famous quotes containing the words nested and/or radical:
“I was asking for something specific and perfect for my city,
Whereupon lo! upsprang the aboriginal name.
Now I see what there is in a name, a word, liquid, sane, unruly,
musical, self-sufficient,

island sixteen miles long, solid-founded,”
—Walt Whitman (1819–1892)
“A radical is a man with both feet firmly planted in the air. A conservative is a man with two perfectly good legs, who, however, has never learned to walk forward. A reactionary is a somnambulist walking backwards. A liberal is a man who uses his legs and his hands at the behest ... of his head.”
—Franklin D. Roosevelt (1882–1945)
