...it would not be quite right to say that the problem is unsolvable in principle; only so complicated that it is not worth anybody__ time to think about it. So what do we do?In probability theory there is a very clever trick for handling a problem that becomes too difficult. We just solve it anyway by:(1)__making it still harder;(2)__redefining what we mean by __olving_ it, so that it becomes something we can do;(3)__inventing a dignified and technical-sounding word to describe this procedure, which has the psychological effect of concealing the real nature of what we have done, and making it appear respectable.
