What does that mean?

I have heard several origins for the phrase "Que sais-je?" but all roads seem to lead to the medieval French philosopher Michel de Montaigne. The phrase can be translated as "What do I know?" It reflects my feeling that the farther along I move on the path of academic enlightenment, the greater the chasm between me and understanding. So I choose to adopt it as my motto. Hell, it's better than my Logie ancestors' motto: "Tam marte ovum arte" (which roughly translates as "brawn over brains" and is shared with the Royal Troon golf club).
