I previously instigated and participated in the following three discussions.
1. "All Propositions Are True," http://www.debate.org...
2. "All Propositions Are True," http://www.debate.org...
3. "All Propositions Are True," http://www.debate.org...

The next paragraph is verbatim an argument I used in my opening arguments for the three aforementioned discussions.

Consider the proposition p = "A rectangle is a square." Since some rectangles are squares, a rectangle is a square. Thus, p is true. Since some rectangles are not squares, a rectangle is not a square. Thus, p is not true. So by Conjunction Introduction, p is true and p is not true. But that is a contradiction. Since every proposition follows from a contradiction by the Principle of Explosion, the proposition "all propositions are true" is true. Therefore, all propositions are true.

If all propositions are true, then the proposition "Not all propositions are true" is true. This implies that the aforementions premise is not universally true.

However, the proposition "Some propositions are true" is both true and is not self-defeating, as my opponent's proposition ensues.

Another argument:

Not all squares are rectangles. All rectangles are squares. Since all squares can be both rectangles and also be said of a larger genus, namely that of shapes, it cannot be said that it is necessarily or sufficiently true that all propositions are true. Therefore, my opponents argument is refuted.

Another argument, from nebular displacement math:

Propositions = 2
True = 1
False = 0
All = 7

7^1-n*(sk^(2*0*1))*sin(7n) = 0

Therefore, it is not true that all propositions are true.

From the last paragraph of my opening argument, all propositions are true. Since "not all propositions are true" is a proposition, the proposition is true. Thus, not all propositions are true. So by Conjunction Introduction, all propositions are true and not all propositions are true.

As the form and content of the argument that is the last paragraph of my opening argument suggest, the proposition "all propositions are true" is universally true in the sense that it is necessarily true.

I agree that the proposition "Some propositions are true" is true, but regarding the issue of whether all propositions are true, I don't see where its truth leads to.

I disagree with your premise that not all squares are rectangles. I also disagree with your premise that all rectangles are squares. That argument of yours is not sound.

I'm not familiar with nebular displacement math. Your argument allegedly involving it appears to be nonsense. An Internet search(1) and its apparent lack of results regarding nebular displacement math support my position.

Your argument for round 2 is the same poor argument you provided for round 1.

Yes it is not true that all propositions are true. If all propositions are true, then the proposition "Not all propositions are true" is true. This implies that the aforementions premise is not universally true. Not all squares are rectangles. All rectangles are squares. Since all squares can be both rectangles and also be said of a larger genus, namely that of shapes, it cannot be said that it is necessarily or sufficiently true that all propositions are true https://www.reecoupons.com... . Therefore, my opponent"s argument is refuted.
