“Only then, when you can argue better against yourself than others can, have you done the work to hold an opinion. That is the time you can say, ‘Hey, I can hold this view, because I can’t find anyone else who can argue better against my view.’”
It’s easy to have an opinion, but it’s hard to have a meaningful opinion.
If you don’t do the work, you’re just reciting somebody else’s opinion. But if you do the work, you’re then not only able to form an opinion, but also able to answer the next question.
