I have recently come to the conclusion that there are cognitively functional people with a sound mind that believe that it is not possible to know anything for sure. Like, it’s not possible to know if the scientists are telling the truth. We just have to take their word for it. Why not stick to the thousand year old belief system then? It has better apologists, armed with an experience of hundreds of years of demagogy and dogma regarding fending of criticism of said belief system.
