    We’ll move onto Natural Deduction in the next chapter, and that’s a continuation of propositional logic. I’ll have a lot more to say about logic in general, its usefulness, and its value at the end of Chapter 7. If you won’t be studying natural deduction, please do go and read sections 7.5 and 7.6 as I think they are important things to think about after learning a bit of deductive logic. For now, let me just congratulate you! You’ve learned how to take English sentences, symbolize them into formulas in propositional logic as a means of symbolizing the logical form of those sentences, and then you learned how to use those symbols to learn things about the original sentences you were symbolizing. You can now test for the validity of inferences and the consistency of sets of propositions, among many other things. I mention these two because I think they’re probably the most useful of the set of analyses you can now run on an argument or set of statements. That’s all for now!
