Tail-wagging in Animals

Famous quotes containing the word animals:
“Man is head, chest and stomach. Each of these animals operates, more often than not, individually. I eat, I feel, I even, although rarely, think.... This jungle crawls and teems, is hungry, roars, gets angry, devours itself, and its cacophonic concert does not even stop when you are asleep.”
—René Daumal (1908–1944)
