You've also given me my working definition for reason now - that is, a definition of reason that works better for how I think of things. I've always known of the certainty part of reason, but never considered the conflicting. In the context of "reasoning through" something, yes. But reason often stands as almost a divine level in discourse: Reason! as if that is all there is to be said about something. No longer though. Conflicting Form of Certainty it is. My mental imagery has Mr. Spock staring down at the black and white squares of a chessboard, trying to decipher the true nature of the line between while simultaneously considering the nature of blackness and whiteness and his own role in it all.
