This long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.

One blames politicians, not for inconsistency but for obstinacy. They are the interpreters, not the masters, of our fate. It is their job, in fact, to register the fact accompli.

The book, as it stands, seems to me to be one of the most frightful muddles I have ever read, with scarcely a sound proposition in it beginning with page 45 [Hayek provided historical background up to page 45; after that came his theoretical model], and yet it remains a book of some interest, which is likely to leave its mark on the mind of the reader. It is an extraordinary example of how, starting with a mistake, a remorseless logician can end up in bedlam.

It is preferable to regard labour, including, of course, the personal services of the entrepreneur, and his assistants, as the sole factor of production, operating in a given environment of technique, natural resources, capital equipment and effective demand.

If you owe your bank a hundred pounds, you have a problem. But if you owe a million, it has.

Ideas shape the course of history.
