I have a confession to make, I can make no sense of probability as degree of belief. The measure-theoretic definition (due to Kolmogoroff?) suits me and I have never progressed beyond it. I can do naught but beg your forgiveness.
You don't need anyone's forgiveness. But it turns out that quantifying degrees of belief is useful sometimes, and that representing them as numbers from 0 to 1 that behave like probabilities is a good way to do that. (There are theorems that kinda-sorta say it's the only way to do that, if you want various nice-sounding things to be true, but how much you care about those nice-sounding things is up to you.) So you may be missing out on some useful thinking tools.
The idea with the format of this thread was to highlight why a given book was better than another two, so that other people (with different tastes and needs) can make a more informed judgment.
That remind me of what we had in our house. It wasn't used much for cooking, stews maybe that's all I recall.
