Logic & Reasoning

Logic is concerned primarily with (1) validity of arguments and (2) consistency of propositions. A valid argument is one in which, if the premises are true, the conclusion cannot fail to be true. Two propositions (factual assertions) are consistent if they can both be true at the same time. The science of logic seeks to understand what it is that makes arguments valid or invalid and what makes propositions consistent or inconsistent. (source: John M. Frame from “Logic”)

Reason does not stand over the gospel, deciding which map to accept and what to reject. Here Christians and postmoderns agree: reason itself is always already situated. Postmodern philosophy is never “from above.” Christians are therefore entitled to assume the gospel as the ultimate interpretive framework with which to make sense of all other knowledge and experience. To reason Christianly is to negotiate the real world with the aid of biblical maps. Reason here plays a ministerial role. But are we rational in accepting just these maps? I believe that rationality is less a matter of starting points or neutral ground than it is a matter of being willing to put one’s faith commitments to any number of critical, even existential, tests (source: Kevin Vanhoozer Christianity and the Postmodern Turn pg. 86)
