Pat11i Concepts. in an 19. Ifp v q is a tautology for two statements p and g, then p. q must be a self-contradiction. 20,--Every argument with a tautology for a conclusion is deductively valid. 21. If a valid argument has a self-contradiction as its only premise, then the conclusion must also be a self-contradiction. 22.1fp . q is a tautology, then so is p v q. 23. 24. A statement of the form p q will always have the same truth value as q p. If p and q are each contingent statements, then p v q must also turn out to be contingent.
