Metalogic

The study of logic itself—the principles, systems, and assumptions that underlie logical reasoning. Metalogic doesn't use logic to argue about the world; it uses logic to argue about logic. It asks: What makes a logical system consistent? Complete? Decidable? What are the limits of formal systems? (Gödel's incompleteness theorems are metalogical results.) How do different logical systems relate? Metalogic is logic turned reflexive, examining its own foundations, its own tools, its own boundaries. It's the discipline that prevents logic from becoming dogmatic by forcing it to confront its own contingency.

"You're so confident in classical logic. But metalogic asks: is classical logic consistent? Complete? Decidable? Gödel showed that any sufficiently powerful system can't be both consistent and complete. Metalogic doesn't destroy logic—it shows logic what it can and can't do. Without metalogic, logic is just prejudice with notation."

Cognitive Metalogic

An area of metalogic and a subfield within infralogic that studies how human beings—individually and collectively—cognitively process, deploy, and respond to logical structures. Cognitive metalogic asks not just what logic is, but how actual human minds do logic: how we perceive logical relationships, how we generate inferences, how we recognize (or fail to recognize) fallacies, and how social contexts shape our logical judgments. It examines the gap between ideal logic (what perfectly rational agents would do) and real logic (what actual humans actually do), exploring how cognitive biases, social pressures, and psychological factors inflect logical practice. Cognitive metalogic is the psychology of logic—the study of logic as a lived human activity rather than an abstract formal system.

Example: "He couldn't understand why his perfectly valid syllogism convinced no one. Cognitive metalogic explains why: humans don't process logic in isolation—they process it through trust, emotion, and social identity, and his argument failed at all those levels."

Metallicar

A black '67 Chevy Impala driven by Dean Winchester, passed down to him by his father, in the show Supernatural. It is called the 'Metallicar' due to Dean's love for rock music and Metallica particularly. The Metallicar was heavily damaged in the final episode of season 1. It was hit and basicly destroyed by a 18 wheeler driven by a demon possesed driver. Early in season 2 it was totally repaired by Dean, with some help from his brother. The car has been prominently featured on the series otherwise, beginning with the teaser of the pilot. The trunk holds various weaponry to fight the supernatural as well.

The main Impala used has a 427 and skid plates. The car was bought new in 1967 at Mathews Chevrolet in Farmingdale, NJ.

Fan1: "Hey, you got nothing but Motorhead, and '80's rock in your dash-CD player. You got yourself a Metallicar here."

Fan2: "You bet I do, now shutup Sam."
