Fundamentally, people are expected to treat and be treated with respect. It’s abnormal when they are not.
Why would not thinking there are big questions out there make someone confident?
But, I don’t know. I’m never full sure the molecules of my chair, floor and earth will continue doing what they do and my body won’t just suddenly shoot through to the center of the earth painlessly inbetween bits of matter.
I know it won’t and yet if it happened, I also would be like “well, I guess it was gonna happen one day”.
