Why should they be happy when it is not their life's inclination to be restricted? Life did not give a bird wings in order to stay in a cage. Wings were given as the means to enjoy life, to make a nest where the birds can live, to make the acquaintance of other birds, to enjoy the life of the jungle, and to find water and food for the comfort and ease of their family. It is in this way that they make their being; it is the same with animals and birds as it is with plants. For them also life means to have a being, to move; it is what life demands.
