An appeal to polysemy, also referred to as an appeal to ambiguity, is a logical fallacy that occurs when someone argues that a proposition is true because it has multiple possible interpretations. This fallacy is based on the assumption that if a proposition has multiple meanings, then it must be true in at least one of those senses. However, this is not necessarily the case. Just because a proposition has multiple possible interpretations does not mean that any of those interpretations are actually true.
The appeal to polysemy is often used to support claims that are vague or ambiguous. For example, someone might argue that the Bible is true because it can be interpreted in many different ways. However, this does not mean that any of the interpretations of the Bible are actually true. It simply means that the Bible is a complex and ambiguous text that can be interpreted in a variety of ways.
