One example will help define the discussion. Take the case of a street railway conductor, whose union has ordered a strike. What determines the law of his conduct under the circumstances? Evidently the existing ethical institutions of which he is a member, so far as he is conscious of their needs. To determine what he should do, he does not hunt up some law of an 'ought' apart from what is; if he should hunt for and should find such a law he would not know what to do with it. Just because it is apart from his concrete circumstances it is no guide, no law for his conduct at all. He has to act not in view of some abstract principle, but in view of a concrete situation. He considers his present wage, its relation to its needs and abilities; his capacity and taste for this and for that work; the reasons for the strike; the conditions of labor at present with reference to winning the strike, and as to the chance of getting other work. He considers his family, their needs and developing powers; the demand that they should live decently; that his children should be fairly educated and get a fair start in the world; he considers his relationships to his fellow members in the union, etc. These considerations, and such as these, give the law to his decision in so far as he acts morally and not instinctively. Where in this law-giving is there any separation from facts? On the contrary, the more right the act (the nearer it comes to its proper law), the more it will simply express and reflect the actual concrete facts. The law, in other words, of action, is the law of actual social forces in their onward movement, in so far as these demand some response in the way of conduct from the individual. We may restate from this point of view, what we have already learned: A moral law is thoroughly individualized. It cannot be duplicated; it cannot be for one act just what it is for another. The ethical world is too rich in capacity and circumstance to permit of monotony; it is too swift in its movement to allow of bare repetition. It will not hold still; it moves on, and moral law is the law of action required from individuals by this movement. The consideration of specific institutions, as the family, industrial society, civil society, the nation, etc., with their respective rights and laws, belongs rather to political philosophy than to the general theory of ethics.
