Walt Whitman by Robert Shetterly, AWTT.org

"This is what you shall do: love the earth and sun and the animals, despise riches, give alms to everyone who asks, stand up for the stupid and crazy, devote your income and labor to others, hate tyrants, argue not concerning God, have patience and indulgence toward the people, take off your hat to nothing known or unknown."

"This self-described "mate and companion of people, all just as immortal and fathomless as myself" (Song of Myself) knew a variety of occupations during his formative years: drifter, printer, teacher, reporter, editor, novelist." Americans Who Tell The Truth

Whitman also served as a volunteer nurse during the Civil War.
