WebDeduction Theorem justifies the technique known as the Rule of Conditional Proof (CP). To prove that q ⇒ r in a line of proof, we temporarily introduce the premise q and if now we can prove r, then by the Deduction Theorem we have proved q ⇒ r and the assumption q may be discharged from further use in the remaining portion of the proof.
