Sorry, but I can't identify the Roger Bacon quotation. 

You didn't ask, but the Babbage quotation comes from his autobiography.
However, he should have known that there are iterative methods that can
improve on lousy guesses. Many Stata users depend on such methods every
time whenever they use -ml-, unknowingly or not.

Roger Bacon (1214-1294) observed that we learn twice: once when we  
observe the general rule, and again when we examine the exceptions.

While I was trying to source this quotation (and I didn't, but I bet  
Nick Cox knows!), I came across this gem:

Babbage, Charles (1792-1871)
"On two occasions I have been asked [by members of Parliament],  
'Pray, Mr. Babbage, if you put into the machine wrong figures, will  
the right answers come out?' I am not able rightly to apprehend the  
kind of confusion of ideas that could provoke such a question."
