A Dog Is a Dog Not a Duck: The Law of Identity

Seems obvious, right? Well, for most of history it was. The Law of Identity, which holds that a thing can be identified by its characteristics, has long been considered foundational to how we think and reason. These days, however, we can no longer assume people accept this to be a true and necessary presupposition for validating truth-claims, let alone for living life.

A well-known Christian pastor and blogger recently tweeted that before we can do preevangelism, we may need to convince people of the law of non-contradiction. While I certainly agree, I would suggest that before we can even do that, we may need to first convince them that a dog is a dog and not a duck.
