In nature a trace of wisdom can be found by studying instinct: among birds, the art of making a nest, among fishes the art of swimming, and the science that exists among animals and birds, which know their medicine when they are ill. In the ancient traditions of the East there exists a belief that medicine was first learned by the bear. The reason was that the bear knew, when it was ill, where to go and what herb or remedy to find and to take, in order to bring about a cure.
