Random trivia time: The start of Gospel by John: "In the beginning was the Word" -- the greek word used there for 'word' is Logos -- which can translate, among other things, to 'cause' and 'reason', from which we get english words like "Logic" or for that matter to "ratio" -- from which we get words like "Logarithm".

So, really: If you were going for a rationalist omake of the Bible, "In the beginning was Reasoning" might have been better, even if it's from a Gospel and not from Genesis.
