AI Thread Summary
The discussion revolves around the complexities of conditional statements and their implications. The initial statement, "If the following statement is true, then the preceding statement is false," raises questions about its truth value and the nature of its conditional structure. Participants explore whether the implication can be considered true or false, highlighting the undefined conditions that arise. The conversation delves into linguistic interpretations, suggesting that the statement may be seen as a single entity rather than two separate statements. A rephrasing introduces a contradiction, leading to a discussion about the paradoxical nature of truth in such statements. The mention of quantum logic implies a deeper philosophical inquiry into the nature of truth and falsehood. Overall, the thread examines the intricacies of logical statements and their interpretations.

What would you make of the following statement:

If the following statement is true, then the preceding statement is false.

Is the implication false? True?

With these conditional statements, there are few levels of undefined conditions.

What if: If the following statement is true happens to be false, then is the preceding statement false or true? So the following statement is defined as an indefined quantity. Otherwise, your conditional statement seems true to me.

In terms of linguisitcs of your statement... it is rather strange.

how should we interpret this sentence as one conditional statement or as two statements?

You said it yourself - this is just one statement. There is no following or preceeding statement here, and if there were, then threre is no problem (in general) that one of them is false and the other true. Now, if you rephrased it somehow, then maybe you'd have a more problematic situation..
 
Just thought of a way to rephrase that:

The following statement is true.
The previous statement is false.

Now you have a contradiction. What's more, neither statement can be true, but also, neiter one can be false. This is problematic... :confused: Quantum logic anyone (true-false superposition)? :wink:

EDIT: A simpler version: This statement is false.

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
