Ditto, absolute certainty is not something I subscribe to. Just because I'm psychologically convinced that something is true/bullshit or am logically certain doesn't mean I acknowledge such to be a certainty in epistemological terms. There is always room for error, no matter how ridiculously large or small that margin may be.
