What is marching?

Famous quotes containing the word marching:

“What if there’s nothing up there at the top?
Where are the captains that govern mankind?
What tears down a tree that has nothing within it?
A blast of wind, O a marching wind,
March wind, and any old tune,
March march and how does it run.”
—William Butler Yeats (1865–1939)

“The chief problem is, of course, whether the marching of the general spirit of things is heading consciously or sub- consciously toward an idea of extension of boundaries.”
—Franklin D. Roosevelt (1882–1945)

“A torchlight procession marching down your throat.”
—John Louis O’Sullivan (1813–1895)
