Nothing mattered except states of mind, chiefly our own. - John Maynard Keynes

When the facts change, I change my mind. What do you do, sir?

Money is only important for what it will procure. Thus a change in the monetary unit, which is uniform in its operation and affects all transactions equally, has no consequences. If, by a change in the established standard of value, a man received and owned twice as much money as he did before in payment for all rights and for all efforts, and if he also paid out twice as much money for all acquisitions and for all satisfactions, he would be wholly unaffected.

I seek only to point out that the principle of accumulation based on inequality was a vital part of the pre-war order of Society and of progress as we then understood it, and to emphasize that this principle depended on unstable psychological conditions, which it may be impossible to recreate. It was not natural for a population, of whom so few enjoyed the comforts of life, to accumulate so hugely. The war has disclosed the possibility of consumption to all and the vanity of abstinence to many. Thus the bluff is discovered; the labouring classes may be no longer willing to forgo so largely, and the capitalist classes, no longer confident of the future, may seek to enjoy more fully their liberties of consumption so long as they last, and thus precipitate the hour of their confiscation.
