... Fitch's Theorem can be avoided by denying the existence of a complete actual situation. In a given context, the actual situation is the — real or imagined — situation that we refer to. In general, there are good reasons not to suppose this situation to be complete. Fitch's theorem might be taken as ...

... Thus, S ∪ T is the set that contains all the elements in S as well as all the elements in T . We remember, of course, that, the “or” in this definition means that if x ∈ S and also x ∈ T , then it is also included as an element of the union S ∪ T. Notice that, since every element x ∈ S is also inclu ...

Algebraic foundations for the semantic treatment of inquisitive content
... 2005, 2010, among others). In this framework, sets of possibilities–also known as alternatives–are not primarily used to capture inquisitive content, but rather to characterize the semantic contribution of disjunction and existentials in the process of meaning composition. Even though inquisitive an ...

... the contrary, it requires in general a DL theorem proving operation. This may clearly be seen by taking a look at our example: the relation between the precondition of rule (1) and the precondition of rule (3) has been determined by relying on the fact that Bird(x) is derivable from P enguin(x) thro ...

Logic and Proof
... Aristotle observed that the correctness of this inference has nothing to do with the truth or falsity of the individual statements, but, rather, the general pattern: Every A is B. Every B is C. Therefore every A is C. We can substitute various properties for A, B, and C; try substituting the propert ...
