'It is a very great mistake, said Burke, many years before the French Revolution is alleged, and most unreasonably alleged, to have alienated him from liberalism: 'it is a very great mistake to imagine that mankind follow up practically any speculative principle, either of government or of freedom, as far as it will go in argument and logical illation. All government, indeed every human benefit and enjoyment, every virtue, and every prudent act, is founded on compromise and barter. We balance inconveniences; we give and take;--we remit some rights that we may enjoy others.... Man acts from motives relative to his interests; and not on metaphysical speculations.[29] These are the words of wisdom and truth, if we can be sure that men will interpret them in all the fulness of their meaning, and not be content to take only that part of the meaning which falls in with the dictates of their own love of ease. In France such words ought to be printed in capitals on the front of every newspaper, and written up in letters of burnished gold over each faction of the Assembly, and on the door of every bureau in the Administration. In England they need a commentary which shall bring out the very simple truth, that compromise and barter do not mean the undisputed triumph of one set of principles. Nor, on the other hand, do they mean the mutilation of both sets of principles, with a view to producing a _tertium quid_ that shall involve the disadvantages of each, without securing the advantages of either. What Burke means is that we ought never to press our ideas up to their remotest logical issues, without reference to the conditions in which we are applying them. In politics we have an art. Success in politics, as in every other art, obviously before all else implies both knowledge of the material with which we have to deal, and also such concession as is necessary to the qualities of the material. Above all, in politics we have an art in which development depends upon small modifications. That is the true side of the conservative theory. To hurry on after logical perfection is to show one's self ignorant of the material of that social structure with which the politician has to deal. To disdain anything short of an organic change in thought or institution in infatuation. To be willing to make such changes too frequently, even when they are possible, is foolhardiness. That fatal French saying about small reforms being the worst enemies of great reforms is, in the sense in which it is commonly used, a formula of social ruin.
