No there is not. There is a **logical explanation** for many things however there are many more things that defy **logic**. These things are usually constructs of humanity. Animals knowing only a rudimentary set of instructions perform in basic **logical** function because they are all driven by basic **logical** need.

**Why is logic** so **important**? The answer is that **logic** helps us better understand good **arguments**—it helps us differentiate between good and bad reasons to believe something.

## Q. What role should Logic play modern argument?

## Q. How do you tell that an argument is valid using a truth table?

In general, to **determine validity**, go **through** every row of the **truth**–**table** to find a row where ALL the premises are **true** AND the conclusion is false. Can you find such a row? If not, the **argument is valid**. If there is one or more rows, then the **argument** is not **valid**.

## Q. How do you write a truth value?

The **truth value** of a sentence is “true” or “false”. A sentence of the form “If A then B” is true unless A is true and B is false. In this case A is “2 is even” and B is “New York has a large population.” I would evaluate each of these as true, so the compound statement is true.
