The Man-Made World

Let us begin, inoffensively, with sheep. The sheep is a beast with which we are all familiar, being much used in religious imagery; the common stock of painters; a staple article of diet; one of our main sources of clothing; and an everyday symbol of bashfulness and stupidity. In some grazing regions the sheep is an object of terror, destroying grass, bush and forest by omnipresent nibbling; on the great plains, sheep-keeping frequently results in insanity, owing to the loneliness of the shepherd, and the monotonous appearance and behavior of the sheep. By the poet, young sheep are preferred, the lamb gambolling gaily; unless it be in hymns, where "all we like sheep" are repeatedly described, and much stress is laid upon the straying propensities of the animal. To the scientific mind there is special interest in the sequacity of sheep, their habit of following one another with automatic imitation. This instinct, we are told, has been developed by ages of wild crowded racing on narrow ledges, along precipices, chasms, around sudden spurs and corners, only the leader seeing when, where and how to jump. If those behind jumped exactly as he did, they lived. If they stopped to exercise independent judgment, they were pushed off and perished; they and their judgment with them.
