Limited Scope

Description: The theory doesn't explain anything other than the phenomenon it explains (that one thing), and at best, is likely to be incomplete.  This is often done by just redefining a term or phrase rather than explaining it.

Logical Form:

Theory X is proposed to explain Y.
Theory X explains nothing else but Y.

Example #1:

My car broke down because it is no longer working.

Explanation: “It isn’t working” is just another way of saying “broke down”, and fails to explain why it broke down.

Example #2:

People often make hasty decisions because they don’t take enough time to consider their choices.

Explanation: Not taking enough time to consider choices is precisely what a hasty decision is.  Again, no explanation is offered, just a definition in place of an explanation.

Exception: If “because” is replaced with a phrase like, “in other words”, then it is a deliberate clarification and not a fallacy.

Fun Fact: Limited depth and limited scope fallacies are sometimes known as fallacies of explanation.

Eat Meat... Or Don't.

Roughly 95% of Americans don’t appear to have an ethical problem with animals being killed for food, yet all of us would have a serious problem with humans being killed for food. What does an animal lack that a human has that justifies killing the animal for food but not the human?

As you start to list properties that the animal lacks to justify eating them, you begin to realize that some humans also lack those properties, yet we don’t eat those humans. Is this logical proof that killing and eating animals for food is immoral? Don’t put away your steak knife just yet.

In Eat Meat… Or Don’t, we examine the moral arguments for and against eating meat with both philosophical and scientific rigor. This book is not about pushing some ideological agenda; it’s ultimately a book about critical thinking.
