WebbThe validity of modus ponens in classical two-valued logic can be clearly demonstrated by use of a truth table . In instances of modus ponens we assume as premises that p → q is true and p is true. Only one line of the truth table—the first—satisfies these two conditions ( p and p → q ). On this line, q is also true. Webb1 apr. 2024 · 1. Why do you need a complete truth table to prove that a sentence is a tautology when you can just make a partial truth table starting with labeling the sentence as false and if it's impossible, the sentence must be a tautology? Take ∼D ∨ D for instance. I make a partial truth table and I assume the statement is false.
