For fidelity, devotion, love, many a two-legged animal is below the dog and the horse. Happy would it be for thousands of people if they could stand at last before the Judgment Seat and say 'I have loved as truly and I have lived as decently as my dog.' And yet we call them 'only brutes' Henry Ward Beecher
Energy will do anything that can be done in the world and no talents, no circumstances, no opportunities will make a two-legged animal a man without it. Johann Wolfgang von Goethe
Man is a two-legged animal without feathers. Plato
