The Road to Serfdom I

There is nothing in the basic principles of liberalism to make it a stationary creed, there are no hard-and-fast rules fixed once and for all. The fundamental principle that in the ordering of our affairs we should make as much use as possible of the spontaneous forces of society, and resort as little as possible to coercion, is capable of an infinite variety of applications. There is, in particular, all the difference between deliberately creating a system within which competition will work as beneficially as possible, and passively accepting institutions as they are. Probably nothing has done so much harm to the liberal cause as the wooden insistence of some liberals on certain rough rules of thumb, above all the principle of laissez-faire. Yet in a sense this was necessary and unavoidable. Against the innumerable interests who could show that particular measures would confer immediate and obvious benefits on some, while the harm they caused was much more indirect and difficult to see, nothing short of some hard-and-fast rule would have been effective. And since a strong presumption in favour of industrial liberty had undoubtedly been established, the temptation to present it as a rule which knew no exceptions was too strong always to be resisted.
