"I have got a scheme to make a thing in the form of a horse with a steam engine in the inside so cont..." — Ada Lovelace

The ideas which led to the Analytical Engine occurred in a manner wholly independent of any that were connected with the Difference Engine. These ideas are indeed, in their own intrinsic nature, independent of the latter engine and might equally have occurred had it never existed nor even been thought of at all.

I was rather foolish in saying that I did not like arithmetic and to learn figures when I did - I was not thinking quite what I was about. The sums can be done better, if I tried, than they are.

I find that nothing but very close and intense application to subjects of a scientific nature now seems at all to keep my imagination from running wild, or to stop up the void which seems to be left in my mind from a want of excitement.

Those who incline to very strictly utilitarian views may perhaps feel that the peculiar powers of the Analytical Engine bear upon questions of abstract and speculative science rather than upon those involving everyday and ordinary human interests.
