Notes and Errata for Calendrical Calculations: Third Edition Nachum Dershowitz and Edward M. Reingold Cambridge University Press, 2008 4:00am, July 24, 2013 Do I contradict myself ? Very well then I contradict myself. (I am large, I contain multitudes.) —Walt Whitman: Song of Myself All those complaints that they mutter about. are on account of many places I have corrected. The Creator knows that in most cases I was misled by following. others whom I will spare the embarrassment of mention. But even were I at fault, I do not claim that I reached my ultimate perfection from the outset, nor that I never erred. Just the opposite, I always retract anything the contrary of which becomes clear to me, whether in my writings or my nature. —Maimonides: Letter to his student Joseph ben Yehuda (circa 1190), Iggerot HaRambam, I.
