 Relevance logic  (or relevant logic) is an attempt to capture the idea that good reasoning requires a genuine condition between premises and conclusions. This should go beyond a mere guarantee of truth preservation. For when a conclusion \(A\) is guaranteed to be true (for example, when it is a logical truth), any argument concluding in \(A\) will preserve truth from premises to conclusions. But those premises may have no genuine connection whatsoever to what \(A\) is about. The same consideration applies when taking a conditional \(A \rightarrow B\) to be valid: there should be a genuine connection between \(A\) and \(B\).
