Logical analysis is an instrument of interpretation to shift the interpretive focus from the purely exegetical approach towards a given text to the systematic reconstruction of a theory that concerns the issues that are discussed. In this way, novel questions can be presented.
Logical reasoning is a mental activity that aims to arrive at a conclusion in a rigorous way. It happens in the form of inferences or arguments by starting from a set of premises and reasoning to a conclusion supported by these premises.

Another influential philosopher, Pavel Tichý initiated Transparent Intensional Logic, an original theory of the logical analysis of natural languages—the theory is devoted to the problem of saying exactly what it is that we learn, know, and can communicate when we come to understand what a sentence means.
Logical, rational or general grammar was the dominant approach to language until it was supplanted by romanticism. [3] Since then, there have been attempts to revive logical grammar. The idea is today at least partially represented by categorial grammar , formal semantics , and transcendental phenomenology ,
Extended logics introduce even more logical constants, like possibility and necessity in modal logic. [21] [36] A sentence is true in virtue of the logical constants alone if all non-logical terms can be freely replaced by other terms of the appropriate type without affecting any change in the truth value of the sentence.
Logic studies valid forms of inference like modus ponens.. Logic is the study of correct reasoning.It includes both formal and informal logic.Formal logic is the study of deductively valid inferences or logical truths.
Aristotle was the first logician to attempt a systematic analysis of logical syntax, of noun (or term), and of verb. He was the first formal logician , in that he demonstrated the principles of reasoning by employing variables to show the underlying logical form of an argument. [ 46 ]
