Sometimes I believe, and sometimes I don't.
Sometimes I don't believe, but pretend that I do, and sometimes I do believe, but pretend I don't.
Sometimes I don't know what I believe, but think about what it would be like to believe either way.
And after all, who really does know what to believe? The idea is inherently contradictory, as belief has at its core a lack of concrete knowledge; faith in the presence of facts is not faith but reason.
