   Logical certainty refers to a state where a conclusion is undeniably   
   true, as it necessarily follows from true premises through valid   
   reasoning, typically in areas like mathematics and formal logic. Such   
   truths, also called absolute truths, are analytic a priori   
   propositions—meaning they can be known independent of sense experience   
   and remain permanent and certain. An example is the logical certainty   
   that "all bachelors are unmarried" because the concept of being an   
   unmarried man is inherent in the definition of a bachelor.

   The base meanings of the terms combined with something you   
   never heard of Frege's Principle of compositionality.

   Unless you use the base meaning of words AS I ALWAYS DO.   
   Logic is most essentially the science of correct reasoning.
