That there is a natural order, with certain inhering laws, men readily accept. That this order has the consistency of being developed in one way; that there is a dip to things that must be followed; that there is a clew, in accordance with which things may be worked; that there is a trend, drift, and law of things that must be accepted and followed; all this, men readily assent to. They do not attempt to farm the Sahara Desert, for they know the conditions of harvests are not there. They do not put out orange groves in Minnesota, nor plant cotton in Canada, nor sow rice in British Columbia. They do not expect the soil that spews up the ice to produce watermelons at the same time. They do not pretend to navigate ships over the continents, and to lay their railway lines on the surface of the sea. They fix their telegraph wires to poles by means of little glass contrivances, and never attempt to send electricity through the grape vine. Natural laws they know inhere in the facts of nature, and are not read into earth and rock and river and atmosphere. They know that necessary laws reside in the facts of condition, and that they must study these laws to know the line of practical work they require. In building a house of stone they know it is necessary to defer to the law of gravity, that this law cannot be ignored or set aside, so they carry up the edifice in such conformity to rule and line as that the center of gravity falls in a line inside the base. They might prefer a house built with reference to a different order of things, one in which the center of gravity would fall in a line outside the base. But it is very well understood among men that the law of gravity must be respected. Even anarchists and nihilists, who seem to have irrepressible antipathy for all ancient orders and laws and establishments, do condescend sufficiently to respect the time-honored, even if slightly belated, laws of gravity.
