we happen to want, we talk entirely in terms of the process and the embryo. The process itself, divorced from its divine object, becomes doubtful and even morbid; poison enters the embryo of everything; and our politics are rotten eggs. Idealism is only considering everything in its practical essence. Idealism only means that we should consider a poker in reference to poking before we discuss its suitability for wife-beating; that we should ask if an egg is good enough for practical poultry-rearing before we decide that the egg is bad enough for practical politics. But I know that this primary pursuit of the theory (which is but pursuit of the aim) exposes one to the cheap charge of fiddling while Rome is burning. A school, of which Lord Rosebery is representative, has endeavored to substitute for the moral or social ideals which have hitherto been the motive of politics a general coherency or completeness in the social system which has gained the nick-name of “efficiency.” I am not very certain of the secret doctrine of this sect in the matter. But, as far as I can make out, “efficiency” means that we ought to discover everything about a machine except what it is for. There has arisen in our time a most singular fancy: the fancy that when things go very wrong we need a practical man. It would be far truer to say, that when things go very wrong we need an unpractical man. Certainly, at least, we need a theorist. A practical man means a man accustomed to mere daily practice, to the way things commonly work. When things will not work, you must have the thinker, the man who has some doctrine about why they work at all. It is wrong to fiddle while Rome is burning; but it is quite right to study the theory of hydraulics while Rome is burning. It is then necessary to drop one’s daily agnosticism and attempt rerum cognoscere causas. If your aeroplane has a slight indisposition, a handy man may mend it. But, if it is seriously ill, it is all the more likely that some absent-minded old professor with wild white hair will have to be dragged out of a college or laboratory to analyze the evil. The more complicated the smash, the whiter-haired and more absent-minded will be the theorist who is needed to deal with it; and in some extreme cases, no one but the man (probably insane) who invented your flying-ship could possibly say what was the matter with it.
