Three Laws of Logic,  Answers

    1. The first law of logic is The Law of Identity.  The Law of Identity states that A is A, that if something exist it has a nature, a single nature.  Something is what it is.



       
  2. What is the second law of logic?
    1. The second law of logic is The Law of Non-contradiction.  The Law of Non-contradiction states that A cannot be both A and not A at the same time and in the same sense. Truth is not self-contradictory.  In other words, something cannot be true if it contradicts itself.  If I said that I went shopping yesterday and then later said I did not go shopping yesterday, both statements cannot be true.

    1. The third law of logic is The Law of Excluded Middle.   The Law of Excluded Middle states that a statement is either true or false.   This means that there is no middle ground as to the truth of a statement.  "It is raining outside"is either true or false.
