The law of negating the negation, exercised unconsciously in nature and in history, and before it is perceived, it also happens involuntarily in our minds as well, – that rule is prominently stated by Hegel for the first time. You can’t spell truth without ruth poster. And if Mr. Ding wanted to follow that rule himself secretly and only the name annoyed him, then he could go ahead and find a better one. But if I don’t want to get rid of the essence of that thing from my thinking, please first of all please take it out of nature and history, and please invent one. in math where – ax – a is not + a2, and in which differential and integral are both prohibited, if anyone does not obey it will be punished.
