I emphasize this because some of my colleagues, for whose academic attainments I have great respect, argue" 'You assume too much; this is not proved; this is not strictly scientific. We disagree with your neurology and your psychiatry is misleading, therefore you must be wrong.' My reply has been, with all humility: 'Yes, of course,' and I have returned to the labor ward to be greeted by happy women with their newborn babies in their arms: 'How right you are, Doctor, it is so much easier that way.' That is what really matters to the clinician. He should use the method that gives the best and safest result from all points of view until something better is discovered.
