The only kind of authority that I recognize is Toby, and maaaaaaybe the secondary devs, such as Temmie.

And the reason is due to what I said in one of the previous posts. Sometimes, his authority is necessary to streamline our theories.

Speaking of ad hominemns... do NOT cite PragerU or Infowars as your source on r/politics. I've learned that the hard way xD

Cicular reasoning is when you assume that something is true, and then use the conclusion stemming from this to prove that it's true. On it's own, it's ok to assume that something is true, as long as you invert the method of confirmatiaon, that is, instead of using the conclusion to prove the original argument, you aim to disprove it, to create a contradiction.

For example, my favorite proof that uses this is the proof that the square root of 2 is an irrational number.

1) Assume that sqrt(2) is rational. I.e., it can be written as the quotient of two positive coprime integers, P and Q.

2) Rewrite sqrt(2) = P/Q as 2Q^2 = P^2

3) Q is whole, ergo Q^2 is whole, ergo 2Q^2 is even, ergo P^2 is even, ergo P is even, ergo P^2 is divisible by 4, ergo 2Q^2 is divisible by 4, ergo Q^2 is even, ergo Q is even.

4) P and Q cannot be both even at the same time since they are coprime. Conclusion, our initial assumption was incorrect.
