Translate the premises and conclusion into the symbols of propositional logic. Construct a truth table in which you analyze the argument for validity. You can construct a truth a table by inserting a table into a Microsoft Word document (from the INSERT option in Word, choose “table.” You will then have an opportunity to choose how many rows and columns you would like your table to be.) Is your argument valid or invalid? If valid, say why it is valid; identify the rows in the truth table that make the argument valid. If the argument is invalid, identify a counterexample; point to a row in your truth table that makes the argument invalid.
3. It is morally permissible for extraterrestrials to eat humans on the condition that it is morally permissible for humans to eat animals. But either it is not morally permissible for extraterrestrials to eat humans or human life lacks intrinsic value. Human life has intrinsic value. Therefore it is not morally permissible for humans to eat animals. (E: It is morally permissible for extraterrestrials to eat humans; H: It is morally permissible for humans to eat animals; V: Human life has intrinsic value)
premises are:-
H->E
~E v ~V
V
conclusion is:-
~H
| H | E | V | H->E | ~E | ~V | ~Ev~V | ~H |

This argument is valid.
There are no rows where the premises are all true and the conclusion is false.
The top 4 rows are the rows that make this argument valid.
