Yes, Keynes was a genius. Yes, some of his ideas were inchoate and would not have lent themselves usefully to diagramming and symbolic manipulation. … - Paul Samuelson

Here is my advice. When in doubt, give my new efforts a hearing. Many feel a calling to break new ground; in the end, few will end upfinding their efforts chosen. But the yea-sayer does do less harm than the naysayer, in that the Darwinian process of adverse testing will in time (most likely?) separate the useful from the useless, the trivial from the profound.

Error is a virus that tends to spread. As I have already hinted, the categories of circulating capital and of the wage fund tended and still tend to get confounded together.

As a theorist I have great advantages. All I need is a pencil (now a ball pen) and an empty pad of paper. There are analysts who sit and look vacantly out the window, but after the age of 20 I was not one of them. I ought to envy the new generation who have grown up with the computer, but I don’t. None of them known to me sits idly at the console, improvising and experimenting in the way that a composer does at the piano. That ought to become increasingly possible. But up to now, in my observation, the computer is largely a black box into which researchers feed raw input and out of from which they draw various summarizing measures and simulations. Not having access to look around in the box, the investigator has less intuitive familiarity with the data than used to be the case in the bad old days.
