Pray tell Mr Babbage, what if you were to only put into the machine the right questions, would the wrong answers come out?
-Some aristocratic idiot 1869, april 20.
EDIT : I should really provide the source just for fun.
On two occasions I have been asked, — "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
