| Logic: logic is the doctrine of the admissibility or inadmissibility of relations between statements and thus the validity of the compositions of these statements. In particular, the question is whether conclusions can be obtained from certain presuppositions such as premises or antecedents. Logical formulas are not interpreted at first. Only the interpretation, i. e. the insertion of values, e.g. objects instead of the free variables, makes the question of their truth meaningful._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Thomas Nagel on Logic - Dictionary of Arguments
I 61 That "and" has become the word for the conjunction by contingent circumstances has no consequences on the status of the true statement that p is implied by p and q. What a set of sentences means depends on conventions. What follows from a set of premises does not depend on them (formal). >Convention, >Logical constants, >Logical truth, >Meaning/Nagel. I 85 Logic/Nagel: logical judgments are based on our comprehension, but they are not a judgment about our ability of comprehension. >Judgments, >Recognition. I 94 Logical skepticism/NagelVsSkepticism/Nagel: we can never reach a point where there are two possibilities that are compatible with all evidence. I cannot imagine that I am in a similar realization situation where 2 + 2 = 5, but my brain would be confused, because I could not imagine that 2 + 2 = 5. The logical skeptic offers no level of reason. There is no point that allows reviewing the logic without presupposing it. Not everything can be revised. - Something has to be maintained in order to check that the revision is justified._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
