What exactly does the word “thesis” mean in this sentence?

Johnny, God bless you, bud. It's been a long time since I was in college, but it looks like the typical task assigned to provoke analytical reading.I’m not sure what you're reading, but the author’s “thesis” is the central proposal, the core idea, the hypothesis that the author of a piece is trying to put forth and prove. If you could sit down with the author, share a drink, look her in the eye, and say, “In one clear sentence, tell me this: what the hell are you trying to say in this piece?” Then her answer would be her “"thesis.” That's what a thesis is. It's the central idea that the author is slaving to communicate.The purpose may be something different and, perhaps, larger. The purpose is not the central idea that she is trying to communicate. The purpose is the answer to this question: “Okay, so now that I understand what you’re trying to say, then the next question is this: why the hell are you saying it? What do you hope this statement will accomplish? The noise you’re making is good, but why are you making it?” The answer to that question would be your “purpose.”To recap, the thesis is what the author is trying to say, expressed in a single sentence. The purpose is what she hopes to accomplish by saying it.Does that make sense?
