Murder is illegal in this country.
But I couldn’t tell you where it says that in the statute-books without doing a bit of research. I can’t cite the exact law off the top of my head, or provide the precise codified wording which strictly speaking makes it illegal to murder another person.
But it’s definitely illegal. I could look all that up if I wanted to. But even if I don’t want to, I’m still justified in believing that murder is illegal. My indirect observations have led me to place a very high probability of truth on that statement, and I don’t think that’s an indicator of poor calibration.
This is relevant to yesterday’s discussion of how homeopathy doesn’t work.
