assumptions, which they themselves 

 are scarcely aware of simply because 

 they are opposed to dragging "spec- 

 ulation" into the open. Thus they may 

 be finally led into the worst blunders 

 of all. Let us, then, frankly admit 

 the uncertainty of many of the pos- 

 sibilities we have dealt with, using 

 them as a spur to the real work.
