A mathematician who pretended to be creepy

And a person who gave up her entire life to know the answer to the question “What is one?” This is Gottlob Frege, a German mathematician who is alive in the 19th century. “And what, this mathematician doesn’t know, what is this one?” - You might be shocked. Utim, how can you explain what “1” means? Maybe there will be people who will show you one apple or one hand and say: “The axle is one thing.” Utim, the apple and the pen are not the same. And about those, and about others, you can say “one”, but why so?
