VIDEOSERIE: Negation and more 🥸📽️
João Marcos: Negation, opposition and contradiction
📍Link: youtube.com/watch?v=MlyG8HT3…
This video guides us through the relation between negation and contradiction, exploring its significance for logic, reasoning, and the philosophy of logic.
It is always a great experience to contribute to @MxLogica!
This is my take on "Negation, opposition and contradiction":

I hope some of you find it enjoyable.

How much confusion in logic comes from treating presentation-dependent properties of connectives, without further analysis, as if they were intrinsic to the connectives themselves?
Eu apostaria que ela ainda não está "pronta" pra isso.

Um atual orientando meu que é aluno do Departamento de Matemática da UFSC foi *proibido* pelo Colegiado da Matemática de escrever seu TCC em inglês. Mais ainda, depois do pedido dele o Colegiado decidiu mudar o regimento para cristalizar a proibição.

"¿Qué diablos es una lógica subestructural?"
Modera: Christian Andrés Romero Rodríguez
I wonder whether this (hermetic?) presentational style is experiencing a resurgence with the rise of proof assistants, whose formal theories rarely prioritize the communication of mathematical intuition. In this context, is communication itself confined to peripheral commentary?

The desiccated "Theorem, Lemma, Proof, Corollary,..." presentational style is staggeringly counterproductive, if one's objective is actually communicating the underlying mathematical intuitions and thought processes behind a result. In reality, the process is more like... (1/4)
