Back when I was in college, I took some philosophy classes just for fun. I discovered when I took Symbolic Logic that while everyone else was struggling with the class, I was finding it pretty easy, because chaining together a proof in symbolic logic felt just like programming. It was the same mental steps: you have the starting conditions, there's an endpoint you want to reach, and you need to chain together these fundamental operations in order to get there. (And sometimes you needed to see how to break them apart: if you need to prove P AND Q, then proving P separately and proving Q separately were usually easier steps, and then once you've proved P and you've proved Q then you've proved P AND Q. Which felt a lot like refactoring a large function that did two things into two separate, smaller functions that do one thing each).
Looking through the sample chapter, I'm reminded of my experience with symbolic logic class. It looks like it'll be much the same thing, but flipped on its head: instead of knowing programming and using that knowledge to make symbolic logic easier, this looks like it'll be about knowing symbolic logic and using that knowledge to make programming easier. Seems pretty useful; I'll give the sample chapters a more in-depth read soon.
