I cannot leave this subject as though its just treatment wholly depended either on our own pledges or economic facts. The policy of reducing Germany … - John Maynard Keynes

The policy of reducing Germany to servitude for a generation, of degrading the lives of millions of human beings, and of depriving a whole nation of happiness should be abhorrent and detestable, — abhorrent and detestable, even if it were possible, even if it enriched ourselves, even if it did not sow the decay of the whole civilized life of Europe.

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

In writing thus I do not necessarily disparage the practices of that generation. In the unconscious recesses of its being Society knew what it was about. The cake was really very small in proportion to the appetites of consumption, and no one, if it were shared all round, would be much the better off by the cutting of it. Society was working not for the small pleasures of today but for the future security and improvement of the race,—in fact for "progress." If only the cake were not cut but was allowed to grow in the geometrical proportion predicted by Malthus of population, but not less true of compound interest, perhaps a day might come when there would be at last be enough to go round, and when posterity could enter into the enjoyment of our labors.

The duty of "saving" became nine-tenths of virtue and the growth of the cake the object of true religion.
