Famous quotes containing the words water and/or quality:

    I respect the ways of old folks, but the blood of a rooster or a goat cannot turn the seasons, change the course of the clouds and fill them up with water like bladders. The other night, at the ceremony for Legba, I danced and sang my fill: I am a black man, no? and I enjoyed it like a true Negro should. When the drums beat, I feel it in the pit of my stomach, I feel the itch in my hips and up and down my legs, I have got to join the party. But that is all.
    Jacques Roumain (1907–1945)

    The courage of a soldier is found to be the cheapest and most common quality of human nature.
    Edward Gibbon (1737–1794)
