Hi TheLastWord, In this case I must defer, for the answer to your question, to William Blake (from "The Marriage of Heaven and Hell") : "As I was walking among the fires of hell, delighted with the enjoyments of Genius; which to Angels look like torment and insanity. I collected some of their Proverbs: thinking that as the sayings used in a nation, mark its character, so the Proverbs of Hell, shew the nature of Infernal wisdom better than any description of buildings or garments. When I came home; on the abyss of the five senses, where a flat sided steep frowns over the present world. I saw a mighty Devil folded in black clouds, hovering on the sides of the rock, with corroding fires he wrote the following sentence now percieved by the minds of men, & read by them on earth. "How do you know but ev'ry Bird that cuts the airy way, Is an immense world of delight, clos'd by your senses five?" best, Bill "Many : not conversant with mathematical studies, imagine that because it [the Analytical Engine] is to give results in numerical notation, its processes must consequently be arithmetical, numerical, rather than algebraical and analytical. This is an error. The engine can arrange and combine numerical quantities as if they were letters or any other general symbols; and it fact it might bring out its results in algebraical notation, were provisions made accordingly."
