The first thing for a business-like understanding of the matter is to understand its limits, and therefore I think it desirable at once to point out and dispel a confusion between morality and law, which sometimes rises to the height of conscious theory, and more often and indeed constantly is making trouble in detail without reaching the point of consciousness. You can see very plainly that a bad man has as much reason as a good one for wishing to avoid an encounter with the public force, and therefore you can see the practical importance of the distinction between morality and law. A man who cares nothing for an ethical rule which is believed and practised by his neighbors is likely nevertheless to care a good deal to avoid being made to pay money, and will want to keep out of jail if he can.
I take it for granted that no hearer of mine will misinterpret what I have to say as the language of cynicism. The law is the witness and external deposit of our moral life. Its history is the history of the moral development of the race. The practice of it, in spite of popular jests, tends to make good citizens and good men. When I emphasize the difference between law and morals I do so with reference to a single end, that of learning and understanding the law. For that purpose you must definitely master its specific marks, and it is for that that I ask you for the moment to imagine yourselves indifferent to other and greater things.
I do not say that there is not a wider point of view from which the distinction between law and morals becomes of secondary or no importance, as all mathematical distinctions vanish in presence of the infinite. But I do say that that distinction is of the first importance for the object which we are here to consider,—a right study and mastery of the law as a business with well understood limits, a body of dogma enclosed within definite lines. I have just shown the practical reason for saying so. If you want to know the law and nothing else, you must look at it as a bad man, who cares only for the material consequences which such knowledge enables him to predict, not as a good one, who finds his reasons for conduct, whether inside the law or outside of it, in the vaguer sanctions of conscience. The theoretical importance of the distinction is no less, if you would reason on youir subject aright. The law is full of phraseology drawn from morals, and by the mere force of language continually invites us to pass from one domain to the other without perceiving it, as we are sure
