Truth Table Method

  • One way of determining whether or not a set of premises logically entails a possible conclusion is to check the truth table for the logical constants of the language

  • This is called the truth table method and can be formalized as follows:

    • Step 1: Starting with a complete truth table for the propositional constants, iterate through all the premises of the problem, for each premise eliminating any row that does not satisfy the premise

    • Step 2: Do the same for the conclusion

    • Step 3: Finally, compare the two tables; If every row that remains in the premise table, i.e. is not eliminated, also remains in the conclusion table, i.e. is not eliminated, then the premises logically entail the conclusion
