On thinking versus doing..............

 . . . the twentieth century saw concerted efforts to separate thinking from doing.  Those efforts achieved a good deal of success in ordering our economic life, and it is this success that perhaps explains the plausibility the distinction now enjoys.  Yet to call this "success" is deeply perverse, for wherever the separation of thinking from doing has been achieved, it has been responsible for the degradation of work.
