Sir Dominic J. Corrigan once stated that the trouble with doctors was not that they did not know enough but that they did not see enough. It is surprising that, as an eminent cardiologist, he did not include the auditory sense in his declaration, but the point is well made. There is still no substitute for accurate observation in clinical medicine and a physician obviously must recognize and specify a problem before he can logically consider a solution. The diagnosis of cardiovascular disease usually requires meticulous attention to phenomena that may appear to many physicians as trivia, and it might seem easier to obtain so-called objective laboratory data. In this context R. C. Cabot was (and still is) right when he implied that such data were not easily transferable like coin without loss of value.
Much of what has been stated has been implied by the authors of the book
