Appearance, Mark Twain

It's not the size of the dog in the fight, it's the size of the fight in the dog.

Investment, John Hicks

Investment of capital, to yield its fruit in the future, must be based on expectations, of opportunities in the future. When I put this to Hayek, he told me that this was indeed the direction in which he had been thinking. Hayek gave me a copy of a paper on 'intertemporal equilibrium', which he had written some years before his arrival in London; the conditions for a perfect foresight equilibrium were there set out in a very sophisticated manner.

- John Hicks, in Money, Interest and Wages (1982), p. 6
