1. I have the same authority as the Pope, but I don’t have as many people believing in it. The implication is that the Pope has many followers and adherents, while my ideas or inventions have no adherents. People will gradually accept and support me.
2. I was asked to remember that I didn’t know something, and my memory was so good that it refused to be tortured and insulted like this.
The situation here may be that the author was insulted, and he used his wisdom to say that he did not understand the curse words and would not remember the curse words.
3. We are born ignorant, but one must work hard to remain ignorant. The meaning is that the harder you study, the richer and more knowledgeable you become, the more you realize how ignorant and stupid you are.
Hope this helps!
