On Minding One’s Own Business
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 to perfect happiness on earth, we are mistaken. The halfway men—the professorial 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.
To mind one’s own business is a purely negative and unproductive injunction, but, taking social matters as they are just now, it is a sociological principle of the first importance. There might be developed a grand philosophy on the basis of minding one’s own business.
