It's only an analogy. The analogy is meant to be "prove that 91 has prime factors" using infinitistic methods, and "prove that 91's prime factors are 7 and 13" using finitistic ones.


I am aware of that. That's why analogies are usually not very useful.


I have no idea how you learn, but analogies are basically the only way I use of absorbing new concepts.


Interesting. I learn by playing around with the concept until I gain some intuition about it. No analogies required.
