What is logic and example?
The definition of logic is a science that studies the principles of correct reasoning. An example of logic is deducing that two truths imply a third truth. An example of logic is the process of coming to the conclusion of who stole a cookie based on who was in the room at the time. noun. 1.
What is logic based on?
