: What about Binyan Av? Tzad Hashavah?

Are these analogies? I believe they describe forms of inductive
reasoning; ie ways to build a kelal from instances.

: Why not fundamentally refuse to see electricity as "fire"?

I didn't say "refuse", I said "afraid of". Analogies have their role,
but they have to be handled with suspicion.

: Or how about the Rosh applying purchasing s'forim as a qiyyum of mitzvas
: k'sivas Sefer Torah?

That's an analogy? It's deduction from first principles. The mitzvah is
defined in terms of a function, which the Rif then says is fulfilled by
other sefarim.

Tir'u baTov!
