It economics is a method rather than a doctrine, an apparatus of the mind, a technique of thinking which helps its possessor to draw correct conclusions.

The spectacle of modern investment markets has sometimes moved me towards the conclusion that to make the purchase of an investment permanent and indissoluble, like marriage, except by reason of death or other grave cause, might be a useful remedy for our contemporary evils. For this would force the investor to direct his mind to the long-term prospects and to those only.

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. This is why we have been able to take labour as the sole physical unit which we require in our economic system, apart from units of money and of time.

Markets can remain irrational longer than you can remain solvent.

It's not bringing in the new ideas that's so hard; it's getting rid of the old ones.

The old saying holds. Owe your banker �1000 and you are at his mercy; owe him �1 million and the position is reversed.
