Truth Table of Buddism/Four fold logic? One thing that I find Buddhism fascinating is the &quot;true contradictions&quot;, which says that there are statements that can be both true and false.
I was googling and found Dialetheism and Catuṣkoṭi on Wikipedia, but I have not found a truth table that represents this idea.
Do anyone know if there are web pages talk about this idea more clearly, and if we can also do a truth table about this idea, compared with the standard mathematical Truth table?

Catuṣkoṭi or tretralemma is mostly made up by  intellectuals who commented on what they thought was the dhamma, and they tried to push their sloppy reasoning as the dhamma too, like Nagarjuna, so it is mostly in Mahayana. None of that stuff is strongly buddhist. The intellectual works like the Upanishads use it too, with their neti neti, and the jains also, to support exactly the same claim like Nagarjuna, ie ''you can't talk about reality'', ie the absolute truth cannot be said with conventional language. Buddhist intellectuals are not really rigorous logicians, even more so when compared to today logicians.
Plenty of people have tried to formalize the tretralemma like here https://arxiv.org/pdf/1405.7744.pdf

Hence the interpretation of this modified catus.kot.i is: If somebody
denies all these alternatives, then he/she intends to mean by
abbreviation using the representatives that he/she declares that the
ultimate truth or the reality can- not be described by any formula of
any propositional calculus in which A is a generic formula.
Particularly any propositional calculus for which A is a sentence
letter doesn’t work to describe the reality.

In the sutras, the tetralemma is just rejecting a claim and also rejecting the negation of the claim. This is from the claim being ill-defined, completely out of topic. But intellectuals prefer to view it has a deep thing about reality.
