Society, therefore, does not need any care or supervision. If we can acquire a science of society, based on observation of phenomena and study of forces, we may hope to gain some ground slowly toward the elimination of old errors and the re-establishment of a sound and natural social order. Whatever we gain that way will be by growth, never in the world by any reconstruction of society on the plan of some enthusiastic social architect. The latter is only repeating the old error over again, and postponing all our chances of real improvement. Society needs first of all to be freed from these meddlers--that is, to be let alone. Here we are, then, once more back at the old doctrine--_Laissez faire_. Let us translate it into blunt English, and it will read, Mind your own business. It is nothing but the doctrine of liberty. Let every man be happy in his own way. If his sphere of action and interest impinges on that of any other man, there will have to be compromise and adjustment. Wait for the occasion. Do not attempt to generalize those interferences or to plan for them _a priori_. We have a body of laws and institutions which have grown up as occasion has occurred for adjusting rights. Let the same process go on. Practise the utmost reserve possible in your interferences even of this kind, and by no means seize occasion for interfering with natural adjustments. Try first long and patiently whether the natural adjustment will not come about through the play of interests and the voluntary concessions of the parties. I have said that we have an empirical political economy and social science to fit the distortions of our society. The test of empiricism in this matter is the attitude which one takes up toward _laissez faire_. It no doubt wounds the vanity of a philosopher who is just ready with a new solution of the universe to be told to mind his own business. So he goes on to tell us that if we think that we shall, by being let alone, attain a perfect happiness on earth, we are mistaken. The half-way men--the professional socialists--join him. They solemnly shake their heads, and tell us that he is right--that letting us alone will never secure us perfect happiness. Under all this lies the familiar logical fallacy, never expressed, but really the point of the whole, that we _shall_ get perfect happiness if we put ourselves in the hands of the world-reformer. We never supposed that _laissez faire_ would give us perfect happiness. We have left perfect happiness entirely out of our account. If the social doctors will mind their own business, we shall have no troubles but what belong to Nature. Those we will endure or combat as we can. What we desire is, that the friends of humanity should cease to add to them. Our disposition toward the ills which our fellow-man inflicts on us through malice or meddling is quite different from our disposition toward the ills which are inherent in the conditions of human life.
