The projection problem happens because **presuppositions are not always preserved when embedded in complex sentences**. <br /><br />Here's a breakdown of why:<br /><br />* **Presuppositions:** These are implicit assumptions that are taken for granted in a sentence. For example, in the sentence "The king of France is bald," the presupposition is that there is a king of France.<br />* **Entailments:** These are logical consequences of a sentence. For example, the sentence "The cat is on the mat" entails that there is a cat and there is a mat.<br /><br />**The Projection Problem:**<br /><br />The projection problem arises when a presupposition is embedded within a sentence that negates or modifies the original statement. The question is whether the presupposition still holds true in the new context.<br /><br />**Let's look at your options:**<br /><br />1. **Presuppositions destroy entailments:** This is incorrect. Presuppositions and entailments are distinct concepts. Presuppositions are assumptions, while entailments are logical consequences.<br />2. **The presupposition has less power than the entailment:** This is also incorrect. Presuppositions are not about power; they are about implicit assumptions.<br />3. **The meaning of the presupposition survives to become the meaning of...** This is partially correct. **The projection problem is about whether the presupposition survives in the new context.** <br /><br />**Example:**<br /><br />Consider the sentence: "The king of France is not bald."<br /><br />* **Presupposition:** There is a king of France.<br />* **Entailment:** The king of France is not bald.<br /><br />The projection problem arises because the presupposition (there is a king of France) is still assumed to be true even though the sentence negates the original statement.<br /><br />**In summary:**<br /><br />The projection problem is a complex issue in semantics that explores how presuppositions behave when embedded in different sentence structures. It's not about power or destruction, but rather about the persistence of implicit assumptions in different contexts. <br />
