Skepticism can imprison you. You start questioning truth and the meaningfulness of anything and everything. Actually, if you take that kind of a route, you can't prove anything. I could take the route of hard doubt and dispute every claim of yours. You will be hard put to prove that you had lunch yesterday, that you have passed high school, or that you have money in the bank. Pliny the Elder said in Historia Naturalis, "The only thing that is certain is that nothing is certain." If that is true then statement is false; if it is false, it is false any way. You can't say nothing is certain. Skepticism can become a prison, because it does not give you anything to believe. Skepticism tends to and turns to slow suicide. Everything becomes relative. There is an answer for the skeptics among you .
