There are plenty of people who believe things that I think are outrageously implausible and un-grounded by evidence who are kind, honourable and ethical. And there are people who have what seems like a more rational view of many things, but still somehow manage to be arseholes about it.
Much like with anything in life really. People like to proclaim and profess but at the end of the day, do they live it?
Spoilers: I think we might have to revisit everything from 'seeing is believing' right up to the uncritical worship of empirical evidence.
Seeing is believing yet, what one sees is unlikely to be the truth and the evidence omits that which is untestable, unobservable and as of yet, unknown which makes it very limited.
