| Logical truth: a statement is logically true if it is true on the basis of its form alone. This finding, however, is not absolute since the logical truth is also influenced by other factors such as e.g. the richness of the object language._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Logic Texts on Logical Truth - Dictionary of Arguments
Read III 67 Logical truth-form: can one really reject a whole range of valid inferences, namely those which, although valid, are not valid because of their form? Yes: The logical truths. For example, "nothing is round and square at the same time". Neither "round" nor "square" are logical expressions, so the form of the statement "nothing is both F and G", which can obviously be made wrong by an appropriate interpretation of F and F. But something must have been overlooked here, because "nothing is both round and square" cannot be wrong! It is a necessary truth! Necessity: the classical criterion of logical deduction does not mention necessity! >Necessity, >Deduction, cf. >Round square._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
