John Maynard Keynes

We have involved ourselves in a colossal muddle, having blundered in the control of a delicate machine, the working of which we do not understand. (from 'The Great Slump of 1930') - John Maynard Keynes

In the long run, we are all dead. - John Maynard Keynes

If we consistently act on the optimistic hypothesis, this hypothesis will tend to be realised; whilst by acting on the pessimistic hypothesis we can keep ourselves for ever in the pit of want. (from 'Essays in Persuasion') - John Maynard Keynes
