byd.1 Second-Order logic
... In short, second-order logic is much more expressive than first-order logic. That’s the good news; now for the bad. We have already mentioned that there is no effective proof system that is complete for the full second-order semantics. For better or for worse, many of the properties of first-order l ...

Knowledge Representation: Logic
... Example: Natural language when used to define first order logic. Let us consider the sentence: The sentence „It is true that John is tall” means the same as „John is tall” Quotation marks indicate the use of metalanguage, the word „true” as well. Thus, whole the utterance belongs to the metametalang ...

... is true not only of resolution, but also for many other calculi. Of the calculi for automated deduction, resolution plays an exceptional role. Thus we wish to work a bit more closely with it. In contrast to other calculi, resolution has only two inference rules, and it works with formulas in conjunc ...
