When I think back on my past, there have been times when I have been wrong. At the time, I thought I was right, sometimes quite fervently so. But then I got new data, or had new experiences, or heard a convincing argument, and so I changed my mind. My beliefs changed.
Logically, it seems likely that there is something that I believe right now that is wrong, although of course right now I think it is right. That’s true for all of us.
What beliefs do you have that might be wrong?
