Law of the Possible Ad Hoc

The principle that ad hoc constructions are always possible—there is always some explanation, some solution, some argument that can be devised for the specific case, regardless of whether it generalizes. The law acknowledges human creativity: faced with a novel situation, we can always invent something that addresses it, even if that something has no broader application. This is the source of both human ingenuity (we can solve unprecedented problems) and human folly (we can justify anything). The law of the possible ad hoc reminds us that possibility is not the same as validity—just because we can invent an ad hoc explanation doesn't mean it's true.

Example: "He needed an excuse for missing the deadline and, applying the law of the possible ad hoc, invented one on the spot—a family emergency, a computer crash, a mysterious illness. It was possible, plausible, and completely fabricated. The law said: ad hoc is always possible. His boss said: next time, plan better. Both were right."
