Defining Terms: Law of Non-Contradiction

Law of Non-Contradiction
2 statements are made that contradict each other.  One must be true and the other must be false.  For example: “There is only one God.” and “There are multiple Gods.”  These statements contradict one another and therefore one must be false.

Ravi Zacharias often uses this example:
A husband and wife are going for a walk down the street for a walk together. They meet another couple on their walk and stop to talk to each other.  One of the other people make a statement “”I hear that both of you are pregnant.”   Immediately  together the wife says “yes” and husband says “no.”  The other couple is confused and waiting for an explanation.  Perhaps she is pregnant, and he doesn’t know yet, or perhaps there is a problem in the marriage.  Whatever the reason a woman cannot be both pregnant and not pregnant at the same time.

This law will keep a person honest when it comes to several things in apologetics.  It will also help someone who is hesitant to make a judgment about a position to decide where they stand on it.  For example in future posts we will discuss evidence that the universe had a beginning.  According to the law of non-contradiction  the universe either had a beginning or it did not.  Atheists have motives for not wanting the universe to have a beginning, because ever effect has a cause.  Christians gladly point to God as the first cause.  Even the Big Bang Singularity points to a beginning, even though it is not accepted by many Christians.    That’s why physicists like Stephen Hawking and Roger Penrose are continuing to work on other alternative theories about the origin of the universe.
