Phil;

	I think it is great that you've attempted this statement 
though I am not certain how it will be used.

	Maybe I am tired and a bit cranky (after a long week) but I 
think the ladder analogy needs some reworking. Science is more 
represented by a tree or bush like structure with branches (questions 
leading to investigations) going  every which way as one question 
leads to another and taking off in another direction only limited by 
scientists insights and experimental abilities. This is not unlike 
the older diagrams of evolution as a ladder culminating in man. This 
ladder suggests there is one answer when in fact there are a 
multitude.

If you wish to use the ladder analogy then I would suggest it's use 
for one idea eg evolution. Each rung being the answer to a question 
that leads to another question and answer (that is the next rung) and 
so on and on. The broken rung could then represent results that are 
not verifiable. But only for the line of questioning.


Sincerely,

Martin
