But the _fixedness_ belonging to various orders of law, subsisting in a state of interdependence, and involving subordination of lower to higher, needs some more exact interpretation. The fixedness of law, physical, intellectual, moral, and spiritual, in no case involves fixedness of result, but _varying results according to diversity of conditions_. There is fixedness of physical law, but withal there is diversity of weather, and seasons, and harvests, and that because a variety of conditions are harmonized under fixed law. There is fixedness of intellectual law in accordance with which accuracy of thought is determined, but diversity of result according to the materials with which we deal. And so it is with moral and spiritual law, providing for the regulation of our higher life. What then needs to be pondered by way of reaching an ampler interpretation of the formula of "fixed law" is that it does not in any case imply an iron rigidity of result, an undeviating uniformity of occurrence. There is no region in which perpetual change can be more accurately postulated than in the physical world. But there is order and system in these changes, admirably illustrated in the weather forecasts of the present advanced stage of physical science, which are attainable only by continual watching of shifting conditions with application of fixed law to the appearance of wind and cloud and rain. But there are no forecasts without these two things, fixed laws and varying conditions for their application. With the wider generalization which admits of recognition of fixed law, there is always the narrower, concerned with variable conditions to which the wider is to be applied. So it is under moral law, and so under spiritual. So also does it hold when our observation is directed on interdependence of two orders of law, such as the moral and physical. This combination we have in human life, as it is subjected to both. Physical law reigns in human history as illustrated by the laws of health, which are fixed irrespective of moral law, so that sewerage gas will be prejudicial to health, apart from the moral character of a man. Moral law reigns in human life, and truthfulness in utterance, or justice in action, will maintain a harmony of the inner life, whether outwardly there be poverty or wealth. These two orders of law are independent, yet interwoven in their application to the complex life of man. Immorality will find its accompaniment in physical disorder; the repentance which has healing power within the mind will not heal the body, yet may there be advance in moral life by reason of the weakness and suffering which repentance can not remove. Such is at once the independence and the interdependence of physical and moral law, in accordance with the fixedness of law in each case, and the harmony of both under one government, by means of subordination of the physical to the moral.
