Do Logical Truths Carry Information?
The paper deals with the question whether logical truth carry information. On the one hand it seems that we gain new information by drawing inferences or arriving at some theorems.

متن کاملA Defense of Contingent Logical Truths∗
A formula is a contingent logical truth when it is true in every model M but, for some model M , false at some world of M . We argue that there are such truths, given the logic of actuality.

We argue that this extension is the philosophically pro...
