I promise it picks up somewhat, and I'm sure you'll enjoy the later sections on proofs, comparability, infinity, and set theory (cardinals; large ones touched on too).

I warned the beginning was a bit slow, especially if you've read such things before, but it does a great job of describing the various schools of thought at the time.

The arc of math focused on is interesting historically, as it's arguably these foundational questions which pushed more formalism and rigor in late 19th century-present (my opinion based on others' opinions, I'm no expert). Calculus/diff equations were being used all over the place, but the exact understanding of limits and infinitely were shaky until all this stuff came around.
