The buzzard has nothing to fault himself with. Scruples are alien to the black panther. Piranhas do not doubt the rightness of their actions. The rattlesnake approves of himself without reservations. The self-critical jackal does not exist. The locust, alligator, trichina, horsefly live as they live and are glad of it. The killer-whale’s heart weights one hundred kilos but in other respects it is light. There is nothing more animal-like than a clear conscience on the third planet of the Sun.
