obscure depths with the figures of animals and heroes, or by likening their shining lines of cosmic cloud to a road or highway for the march of beings celestial and terrestrial. Thus, for the speakers of Sanskrit the Milky Way was "The Path of the Gods"; the Lithuanians dubbed it "The Bird Road"; in Low German it is known as "The Way of Cows"; the Cymris associated it with the course of the wind; for Scandinavians it was "The Road of Winter"; the Persians viewed it as the route along which the straw carrier drew his burden; to this day the Winnebagoes call it "The Way of the Chiefs."[F] Science itself is indebted to terms and phrases in which outer realities are assimilated to the circumstances of the life lived by man and by the societies which he forms. Such words as "attraction," "repulsion," "resistance," "nature," "body," "atom," "current," contain obviously anthropomorphic elements. The human origin of the idea conveyed by the term "inertia" may be more or less veiled by unfamiliar Latin elements, yet it is recovered for us again in _Trägheit_, "idleness," the German form of the word. The phrase "natural selection" contains a teleological element which has more than once been used to throw discredit on the process which it describes. And when one observes how persistently such an anthropopathic expression as "affinity" is still applied to chemical reaction, or with what _naïveté_ the term "law" is transferred from the realm of human jurisprudence into the domain of natural processes, one ceases to wonder at the constant confusions of outer with inner in which so much of the psychomorphism of the time has had its origin.
