A quote
If I am hungry, I must eat. Nature does not care whether the bread is the coarse kind or the finest wheat; she does not desire the stomach to be entertained, but to be filled. And if I am thirsty, Nature does not care whether I drink water from the nearest reservoir, or whether I freeze it artificially by sinking it in large quantities of snow. Nature orders only that the thirst be quenched; and it does not matter whether it be a golden, or crystal, or murrine goblet, or a cup from Tibur, or the hollow hand.
