An argument is composed a sequence of multiple 202204281244#. The last sequence of it is the conclusion of the argument. All previous statements are called premises, assumptions or hypotheses. For an argument to be valid, both conclusion and premises must be valid in form and #logically sound.
To test the validity of an argument, follow the procedure below:
- Identify the premises and conclusion of the argument
- Construct a 202205061151# showing all the truth values of them.
- Verify that the truth values for conclusion for every critical row are all true.
Critical row means a row of truth table which all the premises are true. If the conclusion is true in every critical row, then we can say that the argument is valid. However, if it is false in one of the critical rows, then the conclusion is false, which implies the argument is invalid#.
There are various form of arguments that is valid which they are called the rules of inference. They are shown as below:
